 Hello everybody, my name is Nikolas Hafner and today I'm going to show you ST's low voltage motor control portfolio for analog and power. So, let's jump into it. So here we see a quite standard block diagram of a motor control application. But at first, when we talk in ST about low voltage motor control, we talk about DC bus below 100 volts. This is our definition of low voltage. So, looking at the diagram starting from left to right, we see on the left side the power supply. This can be, for example, a lithium-ion battery or a industrial battery in the range of 20 up to 30 volts or a DC bus. Then in the middle in the gray block, we see the microcontroller. This will not be part of this presentation. Then on the right side in the dark blue block, we see the inverter section with the driver and the MOSFET. Then we have also a DC-DC converter or a switching regulator or LDO which bus regulates the voltage to 3.3 volts to supply the microcontroller or to supply the driving section. And then maybe to close the loop, we have also a signal conditioning for current sensing. So to which application can this diagram applies a lot in the industrial segment. For example, in industrial optimization, for applications for robotic arms, moving belts or big equipment, and also in the segment of home optimization. There we have, for example, a roller shutter, cleaning robots, which are battery-powered. Then we have also the consumer market that can apply, for example, for drones, for deep renders, e-bikes, scooters, and also for some small toys. So what else can ST offer? We have also a longevity program. And what this is, I will show you on the next slide. So here you see what I mean when I talk about longevity program. It means that ST ensures a special lifetime of every product from 7, 10, up to 15 years, depending on the product line, to ensure that you can easily reuse the same product for different designs again and again and not have to worry about that it may be vanished in a couple of years. The lifetime of every product or till when it's valid, you can find it on our homepage. For every product, you find a little icon if you search for it on our webpage. There you see till which date is valid. This should make it easier to fit with the requirements of the industrial world. We have also some specific actions on application level. On application level, we ensure an easy testing and valuation for a product. Application specific products are leveraged on the XNUCLEO system. Each product comes with its own XNUCLEO board. It's equipped with our firmware and graphic interface that ensure an easy validation. And if you like it and if you want to design it in, you can easily start to use it for your own product without designing a dedicated hardware for that. This reduces the validation time and the time to market. Empower management is needed in case you need to regulate your bus voltage or the DC voltage to supply a microcontroller or the drivers. And because ST is offering a quite big portfolio, so it's not so easy to select the right one. So how to select the right one? Here are some suggestions, not a complete portfolio overview. But in case, for example, you need efficiency because you have, for example, a battery in front of your motor, then you could go with the L698X family because they're perfect for efficiency applications thanks to the synchronous rectification and the quiescent current. Another example in case you need a solution for a high voltage bus, then the family L798X could be the perfect choice for you for thanks to the asynchronous rectification that can really bring a big benefit for you thanks to a very small duty cycle conversation. Or another example, if you just need a very simple solution and a minimal bill of material, then you should choose, for example, the ST1S. All these products come with a wide package variety from QFM to SO to HSOP up to HTSSOP packages. And in case these suggestions are not fitting to your needs, then ST is offering our tool to help you. So the tool is called eDesignSuit. The link to the tool you find in the very last slide. And here, for example, you see the picture, how it looks like on a website. So you see there's the eDesignSuit. You see a power management design center on the left side. You have also the possibility for a thermal electrical simulation, for a component for signal conditioning design tool, and NFC and RFID calculators and much more. And the tool is very simple. You just put the input voltage and the output voltage in the tool or the need of current, and then the tool gives you the best 3 up to 4 solutions STs offering depending on your needs. Next product family for power management in motor control application are the linear regulators or short LDOs. And there are needed in case that you need a clean voltage rail, for example, for signal conditioning or for the microcontroller. But how to choose the right one? This is always depending on your needs and on the requirements of the application. On the right side here, you can see some suggestions were made. So, for example, if you are interested in a high system efficiency and a minimum power dissipation, you could go with our ultra low drop out LD39X family. Or if you maybe need reverse current protection, then you could go with our LDL112 family. In case you just need a simple and cost effective solution, you could go with our LDK or with our LDL family. ST is also offering a wide package variety. So, as you can see, we are offering, for example, SOA package, PPAK package or SOT package. And all the package have their own advantage. But how to choose the right one? So, to make this easier for you, ST is offering a mobile app, which is available on our web page. And it's called ST Voltage Redulator Finder. And it's quite easy to use. You just enter the electrical parameters. And the device gives you some suggestions which product could fit the best for your application. You also get the latest data sheets there. You have visibility on the stock of this future. And you also get a price indication for every product. In motor control, this means mainly current sensing. But it's quite often overlooked. And to take you some time and take a deeper look, the right choice can bring a lot of benefits. So, you can always go with a standard OPAM, so like our LM290X family. But if you want to have more precision, for example, our TSZ family, enable you to have a much better signal-to-noise result, which allows you to use smaller chance and minimize your overall system losses. Another specific case where the right choice can bring advantage is when you want to track high slow rate signals. Here, for example, our TSZ family could be a good option for you. Or if you want to do some overcurrent detection for overcurrent protection, our TSZ family could be the best choice for you. Because ST have a lot of products, and the high number could for some of you be overwhelming, ST is offering a tool. It's a tool which is called OPAM Finder. And it's available for smartphone. So it's available on the App Store and on the Google Play Store. And it's working quite similar to the other tools. So you just input your electrical parameters and the tool will give you a suggestion of three, four products which could fit best to the application. So let's go on to the core of the application. Now we come to the core of the application, the low voltage motor control section, the inverter section. More or less, it's the same schematic we already saw some slides before. In magenta, we see the products we already discussed, the DC-DC converter and the power sensor. We split the inverter section into two blocks. One is a control logic with a driver. The other one is the power stage for the MOSFETs. We also explore the concept of motor, which is a standard one, a generic one into three different kind of motors. So we have DC motors, we have stepper motors, and we have BODC motors. Each requires a dedicated solution and increase the complexity of the application. Each can use a standalone block or combined with other ones in a kind of labor approach. This brings a big variety and we will go to all the solution one by one to see which is the best and when it's the best. Here we see the different solution ST is offering. For the highest level of flexibility, ST is offering three different solutions. This allows motor control designers to select the best fitting for their project. The first solution is the discrete one, the second one is the interval. Let's start with the discrete approach. What does the discrete approach mean? It means we have a separate microcontroller, a separate gate driver, and a separate power stage. This approach allows us really to choose the microcontroller or the gate driver or the MOSFET we want to use, which fits the best to our projects and is suitable for our requirements. Another big advantage of this approach is a better terminal performance, thanks to a better heat dissipation due to the distance of the interval devices to each other. First product we're going to review for our discrete solution is the gate driver. This one is the SD drive 101, so this is the first block of the schematic we saw in the slides before, so we have the control logic with the driving section. The driver is a 75 volt triple half bridge gate driver with integrated bootstrap direct for every high side and a 12 volt LDO, which applies to control logic and the driving section. It comes with a lot of features like VDS monitoring for each power MOSFET, a standby mode for lower consumption, and two flexible driving modes. One was adjustable dead time, the other one the direct driving with interlocking function. It has a current capability up to 600 milliamps and also a lot of features like an undervoltage lockout, an overcome protection, and a thermal shutdown. All these failures can report it to the MicroSync to our ball pin. For higher voltage or other motors like stepper motors, we have also half bridge gate drivers in our control unit like the L638 or L639 or the more performant L649 product family. All infos are available on our website to the power stage part, the MOSFETs. So here you see our strip fed F7 and the new strip fed F8. Both product families are complementing each other, as you can see in the chart on the lower right side. Come with a wide variety of voltages, so they are scalable from 30 volts up to 100 volts. But why do we recommend these products for motor control? So that's basically thanks to this great EMI behavior and the high efficiency of the product. As you can see in the lower middle, the chart with the system efficiency, the F8 is best in class compared to competition, and this is what's key for motor control. Because of this, almost all of our evaluation boards are equipped with these MOSFETs. The target key applications can might be different, so they can be from power tools to e-bikes, palms and pants, and can even go up to forklifts. Let's come to our integrated solutions, the solution two and solution three. Let's have a closer look at it. If we go to integration, we must differentiate the product by power level. Because if we having device with MOSFET inside, we limit the power of the product in terms of current and voltage. Here you see a kind of ranking. As you can see the different power levels, the products are covering. We have several monolithic products. What is a monolithic product? A monolithic product is One Die, which embeds the control logic, driver and the MOSFET. The power level can be from 10 watts up to 50 watts and more. For sure, this is depending on the motor we want to use. And if we want to go higher in power, we have to go with a controller or a system and package. As we have seen, we can rank the different products by power, but this is not enough. We need an ISA classification to make a distinction between the different product families. And this is an example. In the railways, you see a different type of motors. So you see a DC motor, the BLDC motor and the stepper motor. In the column, you see a different product families. If you want to find a commonality, all our monolithic product families are able to support different products, all kinds of motors. The monolithic product families are those in the big blocks. In the small blocks, you see the system package or controller, which are dedicated for a specific type of motor. Now we will see all these families one by one to understand when to use and which are the key parameters to select the right product. And now we come to our integrated power approach, where we combine a gate driver with a MOSFET. This can be in a monolithic or in a system packet way. The big advantage of this approach is that we save a lot of space on the PCB to have a higher power density and have also easier layout. We can also freely choose the microcontroller we want to use. Okay, let's have a look at a product we have with this approach. Here we have our SD-SPIN 200 motor driver series. It's ideal for battery powered applications and contains five part numbers. As I told you before, this is a monolithic approach, so this covers all types of motors from stepper to BLDC and brushed DC motors. The operating voltage is from 1.8 up to 10 volts. It has a current output up to 1.3 amps rms and also a standby mode, which is best in class with less than 80 nano amps. This is fully protected with undervoltage lockout, over current protection and thermal shutdown, and all these comes in a really small 3x3 millimeter qfm package. We have a dedicated part number from F4 stepper motor, so you see the SD-SPIN 220, which supports up to 256 microsteps. We have two part numbers. Here we have our SD-SPIN 800 motor driver series. It integrates in a small 4x4 millimeter qfm package, the control logic, driver and the low RDS on power stage. It can be forced into a low consumption state, and all the devices or office are a complete set of protection like undervoltage lockout, over current protection and thermal shutdown. The voltage range is from 7 up to 45 volts, and we have an output current up to 1.5 amp rms. The 800 series offers a solution for every type of motor, so we have a solution for stepper BLDC and DC motors. Stepper motor driver has a PWM current control with fixed off time and up to 256 microsteps. The BLDC driver is ready for FLC and can be driven into two different driving modes. It supports single and three-stunt solution architectures. The brushed motor is able to drive two motors bi-directional at the same time, or one motor bi-directional with higher power up to three amps. This makes the 800 family a bulletproof solution for your industrial application. Typical application for this product is medical and health care, stage lightning, wending machines, 3d printers, and much more. Higher in power, here we have our best-selling family, the L6-2X family. It's the most fully integrated motor driver with non-dissipative overcurrent protection of the high-side power MOSFET and has a thermal shutdown. It's realized in the BCD multi-power technology, which combines isolated Demos power transistors with CMOS and B-Polar circuits on the same chip. The family offers a solution for DC motors, for BLDC motors, for stepper motors, with different current output and argues on from 2.8 up to 5.6 amps RMS, and it's available in different packages like PowerSO, SO, PowerDIP, and QFM, to fit perfectly to the customer needs. It's really scalable, so we have a basic power stage, which is only driver plus MOSFETs, and then we can have all the different options added one by one. You can see here on the table on the right side, and we have also solution for BLDC and for stepper with unique features matching to the requirements of them. We have our latest motor driver family, the ST Spin 900 family. The ST Spin 900 family is a multi-half bridge driver family, basically for brushed DC motors or for B-Polar stepper motors. Here we have two versions, the ST Spin 948 with four half-bridges and the 958 with two half-bridges. The voltage range is from 5 up to 58 volts, and we have a current output up to 5 amp RMS. The power stage is designed for high dynamic performance, allowing to achieve high frequency PWM control with precise duty cycle. The devices are offering a current limiter with adjustable thresholds and off time with slow or mixed decayed selection. The amplifier amplifiers with fixed implication factors available for current sensing by using an external shunt resistor. The devices also offer an adjustable slew rate, so here we have four fixed values from 0.3 up to 2 volts per nanosecond to guarantee the best trade-off between performance and EMI. The devices also offer a complete set of protections, including over current protection, over temperature and under voltage lockout. The devices also are stand by mode for lower consumption, and all this comes in a 7 by 7 millimeter QFM package for the 958 and in a 5 by 5 millimeter QFM package for the 958. The target application for these products, for example, stage lighting, antenna control, robotics, home appliances, factory optimization, and many more. Here we have our highly integrated stepper motor drivers. So we have two different types here. We have the L647 family, which is a motor driver, where we combine the driving section with a MOSFET. Here we have a voltage range from 8 volts up to 45 volts. It comes in a power SO36 or in a HTSSOAP28 package. Then we have a controller, which is the L648 family. Here we have two part numbers. Here we just have the driving section with a lot of features and functionality embedded, and here we have a higher voltage range. So we can go from 7.5 up to 85 volts. The big advantage of this high integrated stepper motor driver is that we can easily drive multiple drivers by just one microcontroller. Thanks to the integrated intelligence and the stepper sequencer, for example, the microcontroller needs less computing power to control the drivers. Here we also offer different solutions of the driving modes, for example, in a slow, fast or mixed decay. And we have a quite high accurate of the positioning up to 128 microsteps. Thanks to this, we have a smooth and very sudden motion, especially if we work in the voltage mode, which is patented by ST. His modes allowed us to drive stepper motors almost equal to a BLDC motor. At one point, the integration can reach a limit beyond which it's no longer more convenient to go with a monolithic approach. Otherwise, the silicone would become too large and the number of required part numbers would become far too large to cover all the needs of the customers. However, since the need for more and more integration in the market is there, we decided to take a different approach, the system in package approach. Here we combine several pieces of silicone instead of just using one. This allows us a higher power density and we can also use products which are already existing in the portfolio of ST. So we can choose the best devices for the target application and put them together in one package. As you can see here, for example, we have the approach driver as power stage, and this allows us to reach higher power and more integration in one package. Let us see the product behind it. Highest and with multi-driver, the power step one. It's a system package, so the approach you saw before. We combine a gate driver with MOSFETs. So this device integrates 8n channel 60 mA MOSFETs for stepper applications up to 85 volt with an SPI programmable controller providing a full digital control of the motion through a speed profile generation and a positioning calculation. It integrates dual low RDS on for which was embedded programmable non-dissipative over current protection. The device can operate in two different modes. One mode is the voltage mode. The other one is the advanced current control mode to fit different applications need. The digital control core can generate a user-defined motion profile with acceleration, deceleration, speed or target position easily programmed through a dedicated capacitor set. The output of the device is up to 10 mA. It has adjustable output slew rate and can work up to 128 microsteps. It has a sensorless stall detection and an integrated voltage regulator. It has a SPI interface and an over-temperature protection. It has also a charge pump for all the high sites and ADC. All this comes in an 11 by 40 millimeter QFM package and saves up to 67 percent of space on the PCB compared with a discrete approach. You can see the discrete approach on the upper side of the slide and below you see the approach with our power step. Okay, let's see the next system and package approach we have at ST. The next system and package approach we have is the approach where we combine a gate driver with a microcontroller and one package. As you can see below that we have our STM32 combined with a gate driver. This allows us to integrate more intelligent in our drivers. We already discussed the solution one with a discrete approach and the solution two with integrated power come now to the solution three with integrated intelligent. This is what we call in ST our ST SPIN32 family. There we combine a microcontroller with a gate driver and use external MOSFETs to reach higher power. So here we see the integrated intelligence approach. The big advantage of this approach is thanks to the combination of microcontroller and gate driver and a system package. We can reach a high level of integration but we are not limited in power like in the integrated power approach thanks to the use of external MOSFETs and the better heat dissipation. This approach is perfect for applications where space is really rare and the performance should be high. Let's have a closer look at the family which is behind this approach. As I already mentioned before the approach where we combine a microcontroller and a gate driver and a system and package is called ST SPIN32. So here you see an overview about our ST SPIN32 family. It's a highly integrated system package and we have two different lines. We have the F0 and the G4 line. The F0 users are M0 cortex and the G4 user M4 cortex. So let's have a closer look at both of the products. Here we have our ST SPIN32 F0 series. It's a system and package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes. It embeds a triple half-bridge gate driver able to drive power MOSFETs with a current capability of 6 mA single source and ST SPIN32 F0 core. It has also integrated power management so we have a DC-DC back converter which provides 3.3 volt to supply the microcontroller and if you want also to supply external components. Then we have an internal LCO regulator which provides the supply voltage to the gate driver. The integrated operation amplifiers are available for single conditioning and current sensing across the shunt resistors. A comparator with a programmable threshold is integrated to perform the overcurrent protection and we have also our undervoltage lockout in terms of too low supply voltage and the over-temperature protection for the gate driving section. We have also on board a 12-bit ADC and a flash memory of 32 kilobyte. The voltage range of this family is from 6.6 or 8 depending on the version we are using up to 45 volt. Here we have three different versions. We have the standard one then we have the A version and the B version. The A version and the B version is working from 6.6 up to 45 and the standard version is working from 8 up to 45. Depending on the version we have also a different amount of O pumps and because of this also a different amount of GPIOs. All this comes in our compact 7 by 7 millimeter QFN. Key applications of this product family are fans, power tools, drones, robots, battery-powered home applications, industrial optimization. So here we have our ST Spin 32 G4. It's the bigger brother of the ST Spin F0 and it's superior to it in terms of computing power and on driving as well. So the voltage range of this product is from 5.5 up to 75 volts and it's also dedicated for BLDC motors. But here we have instead of an M0 core or M4 core which is so performant that we are able to drive two BLDC motors at the same time with this device. Here we also have a changed power management so we use here a programmable bug regulator with four fixed values to supply the driving section and we have a 3.3 volt LDO which supplies the microcontroller. We have also an embedded standby regulator which supplies the microcontroller in the case that we force the device into a low consumption mode. The signal conditioning here comes with a microcontroller and thanks to the superior microcontroller we have more comparators and more opums on board for better signal conditioning and better current sensing. We have here also VDS MOSFET monitoring on boards so that we can check every status of every power MOSFET we are driving. With this device we can drive BLDC motors in 6-step or FOC and we have all the protections on board we saw on the F-Zero family. The key applications of this product are mainly robotics, garden and power tools, e-box and e-scooter and many more. And all this comes in a 9x9mm QF-M package. So why to choose ST? Basically there are two main reasons. One is product specific because ST is offering a lot of power and analog IC solution which fits to every type of motor and application. We have application specific product with a high scalability in different packages and for different voltage range and then we also offer power management, signal conditioning and MOSFETs. On top of this we didn't mention it because it was not the main topic of this session but all the products can be combined with our microcontrollers and sensors to have a full coverage for the application. Then we have also our ST longevity program across all the product families and the second point is that we provide you with a core end and comprehensive and A-LIM ecosystem. For application specific applications we leverage on the XNuclear system and we can provide you with boards, with libraries and graphical user interface. Then we also offer a lot of support tools like the e-design suite and a lot of other product selectors for smartphones to choose the best O-palm voltage regulator or MOSFET. More information you find in the links you can see below. That's all from my side and thank you for joining the session about power and analog ICs in a motor control application. I invite you to check out on www.st.com for more information.
