 Hello, and welcome to this presentation on ST's Slim Nano Series of Intelligent Power Modules. Slim stands for Small Low-Loss Intelligent Molded Module, and it is a trademark of ST Microelectronics. In this presentation, we will discover ST's Slim Nano Series. These high-performance intelligent power modules are designed to provide the highest level of efficiency in three phase inverters used for motor drives and home appliances in general. We'll take a close look at the features and benefits of the Slim Nano Series and see what makes these IPMs so interesting, including the different package options. We will also talk about how these IPMs cover a wide power range and discuss different approaches to developing applications. Then we will study some benchmarks to verify the power and thermal performance of the second series of Slim Nano Devices, and finally, an overview of tools and software dedicated to our intelligent power modules. Today, ST offers a very complete power product portfolio from discreet to power modules for different power ranges and applications. We offer IGBT and MOSFET discreet products for a typical range from 10 to 5 kilowatts. We also offer Slim Intelligent Power Modules for a typical range from 20 watts to 3 kilowatts. And finally, we have the new AISPAC power modules for a typical range from 3 to 30 kilowatts. ST's Slim Nano Series of Intelligent Power Modules are ideal solutions for industrial and robotic drives, home appliances, welding, pumps, fans and blowers, and air conditioning. In many applications, such as converters and motor control application, the integration of passive and active components is a fundamental requirement to reduce size and weight. The main purpose of IPMs is to introduce a plug-and-play solution with the power stage and driving stage embedded in the same package. High power density, lower losses, and EMI noise, reduced design time, improved reliability, manufacturability and PCB routing are the main benefits that this approach can provide. Now let's talk about the Slim Nano Series. Targeting a power range from 20 to 500 watts, it's an ideal solution for home appliance applications. With the technology and flexibility to address market needs, it is 100% controlled by ST for silicon. Current capability up to 8 amps, package compactness and thermal performance are the main advantages of this series of Intelligent Power Modules. The first series of Slim Nano devices is available in either surface-mounted, SMD, or through-hole TH package solutions, while the second series only has through-hole TH devices. In both cases, it is also possible to monitor their temperature thanks to an embedded NTC thermistor. These features ensure very high reliability, robustness, and package compactness as well as thermal performance and protection, offering customers a large range of PCB solutions. All these benefits make the Slim Nano Series the ideal solution for any three-phase inverter system up to 500 watts. As an inverter configuration-based product, Slim Nano devices combine six switches in a half-bridge topology, which are driven by three high-voltage gate drivers and with an optimized voltage drop-in conduction. Modules are available with current capability up to 8 amps and in two voltage classes, 500 volts in ultra-fast MOSFET technology, and 600 volts in planar or trench-gate field-stop IGBT and super-junction MOSFET technologies. This IPM series also includes a comparator for fault protection, op-amp and open emitters for current sensing, and internal bootstrap diodes as well as interlocking and undervoltage lockout functions. These devices are available in either surface-mounted, SMD, or through-hole TH packages, with mounted slots package options and with either inline or zigzag leads. The basic version has a common pin for NTC and shutdown functions as well as three pins for the op-amp. A custom version is available with the NTC pin separate from the SD pin and without op-amps. All these features make it the ideal solution for a three-phase inverter for motor drives and small fans, roller shutters, dishwashers, pumps, refrigerators, and washing machines. In order to boost the power capability, we introduced the Slim Nano-Second series with an expanded line up to 5 amps in super-conjunction MOSFET technology and 8 amps for trench-gate field-stop IGBT technology to improve the efficiency and isolation voltage, rating up to 1.5 kV RMS per minute. Other upgrades include a higher package thickness for UL certification, a double standoff option, and slots for easy heat sink screwing. With these improvements, the Slim Nano-Second series is able to reach 500 watts which is also very useful for applications such as washing machines and dishwashers. To save space and energy-efficient motor drives up to 100 watts, we developed IPMs in an SMD package. They are IGBT and MOSFET-based, 600 and 500 volts respectively, with current capability up to 3 amps, an optimized voltage drop in conduction, and low electromagnetic interference. On the other hand, these features provide benefits such as high energy efficiency and excellent reliability, space-saving, heat sink-free design, safety isolation, and low noise. We can say for sure that this is the right choice for low-power applications such as roller shutters, small fans, small compressors, and so on. This compact and thermally efficient package enhances reliability and enables heat sink-free designs while the increased creepage and clearance ensures safety isolation. The SMD package is ideal for all application boards where the reflow and wave soldering process are mandatory. It is especially designed for low-power motor drives working in hard switching circuitries up to 20 kHz and up to 100 watts. The nomenclature is very easy and simple to memorize. The letter G refers to the IGBT-based technology. This means that in MOSFET-based IPMs, this letter disappears. IP stands for Intelligent Power Module. X refers to the package type, N for through-hole first series, and S for SMD version, Q for through-hole second series. The next digit refers to the continuous current at 25 degrees Celsius. Y identifies the technology series, H for planar IGBT, HD for planar IGBT with low dead time, C for TFS IGBT, M for MOSFET, but be careful not to confuse between MOSFET and SJ MOSFET. In fact, in this case, the discriminant is the breakdown voltage, 500 volts for MOSFET and 600 volts for SJ MOSFET. The following digit refers to the breakdown voltage divided by 10. TH refers to special features, A for basic features, T means NTC on board, minus H, standard input low side driving, SDT means SD and NTC separated. The last digit refers to the finish options for the leads, L for inline, Z for zigzag, S without standoff. As mentioned, the Slim Nano series is suitable for a power range from 10 up to 500 watts. The various products in the portfolio are classified by package type, switch type, voltage class, continuous current, saturation voltage or on resistance according to the switch type and dead time. A very important thing to note is the lower VSAT thanks to the TFS IGBT technology and the lower RDS on for the super junction MOSFET. As mentioned before, today integration is a fundamental requirement. In this example application for a refrigerator compressor, a more exhaustive comparison between the two discrete and IPM approaches is highlighted. On the discrete side, at least six additional power switches and drivers are needed. On the IPM side, only one component replacing all the previous components is required. This not only reduces the bill of materials, BOM, but also the design time, reducing the number of components to be handled. To verify the performance of the Slim Nano series, we have carried out some benchmarking to compare our IPM solutions with those of a competitor. In a simulation of a fan application, at a peak current of 1.13 amps, the result shows that ST devices offer the best performance over the entire frequency range, with 12% less power loss per switch at 20 kHz. In a different simulation for a washing machine application, at a peak current of around 5 amps, once again, our IPM performs better than the competitor, reducing power losses by at least 6.5% over the entire frequency range. These results confirm that ST's IPMs guarantee better efficiency and a lower junction temperature compared to the competition over the entire frequency range. The Slim Nano II series is available with either IGBT or Super Junction MOSFET technology, but how to choose one instead of the other? Simple. In IGBT technology, the power losses are linear to the emitter current, while in MOSFET technology, the power losses are exponential to the drain current. Due to different power losses on current dependents, we obtain this graph. For low load conditions, MOSFET technology is better than IGBT, while for full load conditions, IGBT technology performs better. In a real refrigerator application, different customers can use different ambient temperature ranges. In order to address the different customer needs, we compared an IGBT-based IPM, A in the figure, with the Super Junction MOSFET-based IPM, called B, with the same current capability of 3 amps, identifying what, for us, is the best case and the worst case. In the best case, on the left side, corresponding to a very low ambient temperature of 25 degrees Celsius, the Super Junction MOSFET-based IPM shows a lower delta temperature over the whole range of input power, which means it offers the best efficiency. In the worst case, corresponding to an ambient temperature of 70 degrees Celsius, the Super Junction MOSFET-based IPM continues to ensure the best efficiency up to 80 watts. What if the customer needs to achieve higher input power? This is possible with the 5 amp IPM, which, thanks to a 37.5% lower RDS on than previous series, is able to guarantee the best efficiency up to 100 watts. Therefore, ST always has the right product to satisfy customer's needs. In order to help our customers design their application and become familiar with our products, ST offers a very complete and easy-to-use evaluation board for low-to-medium power motors. This board is very complete because it includes interface circuits, bootstrap capacitors, snubber capacitors, temperature monitoring, single or three shunt resistors, filters, and so on. With a minimal BOM, T ensures high efficiency and protection against overvoltage, overload, and over-temperature conditions. To ensure customers get the support they need, we have released our dynamic electrothermal simulation software dedicated to power devices. The ST Power Studio, free of charge tool by ST, is a powerful simulator that allows you to both simulate our products and to have immediate access to all the info about the performance of our intelligent power modules. Using this easy-to-use tool, you can set up a mission profile with static or dynamic loads, define the thermal characteristics, and also record all the results in a final report.
