 Hello and welcome to this presentation on VA Power Technology for H-Bridges. I am Luigi Guarazzi and I started working at ST in 2000. I am currently Technical Marketing Manager in EMEA Region for VA Power Smart Feds for Automotive Applications. During my long experience at ST I have helped our product portfolio evolve, which while still performing same function and maintaining an unsurpassed robustness, have reduced their PCB footprints of five times less. The technology evolution of smartfeds was triggered mainly by the automotive market, which is undergoing an increasing electrification of vehicle functions, sustained by a demanding requirements in terms of safety and power optimization, as well as luxury and comfort features. The number of different functions in the vehicle which require motorization, often by brush DC motors, are constantly growing. In addition to traditional applications such as doors, electric mirrors, seats and windows, there is an increasing number of new and appealing applications, such as power trunk lift, electric sliding doors, electric vehicle lock charger and folding cameras. But what is a smart H-Bridge? A VA Power H-Bridge represents a fully integrated solution that is not only to simply power, but also to control and protect any bi-directional loads. In particular, they are ideal for brush DC motors in the harsh automotive environment. So the differentiating factor is smart driving. The M07 H-Bridge's family belongs to the latest state-of-the-art generation of VA Power H-Bridges, and it is designed around four main pillars, argumented reliability, smart and soft motion, miniaturization, argumented safety by embedded protection and diagnostic. Let's see the first pillar, argumented reliability. The VA Power M07 H-Bridges are increasingly used to replace electromechanical relays for controlling DC motors. The main advantages of relay replacement are 10 times longer operating life, weight and space savings, reduced number of external components required for diagnostic and protection. Second pillar, smart and soft motion enabled by PWM. Pulse with modulation at 20 kW is benchmark on the DC motor control arena today. It offers several benefits. A precise and smooth control of motor speed that ensures a high quality feeling, for example a noiseless smooth activation of a trunk lift or a side mirror. Control of motor torque makes it easier to implement sophisticated functions such as pinch reaction on the final race of a window lift. A reduction of transmitted power so that cabling in the vehicle is not oversized. Third pillar is miniaturization. The M07 H-Bridges are housed in the tiny SU-16 and power SU-36 packages. The advantages in adopting these small packages include the smallest full prints on the market for SU-16 narrow, the best thermal performance on the market for power SSU 36 triple pad packages, a full integration of power MOS and relevant driving circuitry in addition to analog current sense and thermal protection, everything in one single package. Fourth pillar, augmented safety by protection and diagnostics. VA Power M07 H-Bridges feature full silicon embedded thermal protections and diagnostic. There is a fast cut-off and warning diagnostic flag on every kind of short circuit. Here we can see an example on a motor driven by our H-Bridge located remotely in the ECU and suddenly a short circuit appears and the VNH7040 wants the microcontroller of a diagnostic flag. The microcontroller wants immediately the car dashboard and the driver is aware that he has to go to the next service station. Other important features of the augmented safety pillar include high precision motor current readings, non-dissipative current sensing, which means that an external shunt is no longer necessary, thermal protection acting on each MOS of the H-Bridge, detection of missing loads during motor operation as well as during idle states. STS VA Power M07 H-Bridges are the ideal set of devices for driving and protecting brush DC motors used by the previously mentioned loads and applications. The family has a unique set of features that beats the competition by combining tiny power SO-36 triple pad and SO-16 narrow power packages with a wide selection of MOS channel resistance, allowing automotive design engineers to find the best in class solution that covers a wide range of loads from just a few watts up to 200 watts. The bridges offer several competitive advantages, a broad range of on resistances from 8 up to 100 mA per branch. Simple to drive and with diagnostic, only a single pin is required to monitor the motors current, the device case temperature, the battery voltage and the fault flags. The possibility for usage in full H-Bridge, half H-Bridge and cascaded topologies, diagnostic in on and off state. A full and easy to use set of developer resources are available to engineers who can take advantage of many development resources and tools to become more familiar with VA Power M07 H-Bridges. Twister Sim is an electric thermal simulator for VA power products and is available for free of charge. There is a wide variety of evaluation boards that makes it easy for you to test your design by just connecting the load, power supply and microcontroller without any additional effort required for external component design. A sample kit is also available so you can have all our M07 H-Bridges in a single kit. Our solution evaluation kit includes the SPC5 adapter which can be combined with SPC560 discovery board along with the H-Bridge evaluation board for helping you to find the best design for a complete system solution. Let's see the Twister Sim, the electric thermal simulator. This tool helps hardware engineers to match the correct H-Bridge to its application at the very beginning of its development phase. The Twister Sim includes a VA power interactive selector which displays the best device for a given set of inputs like type of device, load and PCB characteristic in just few clicks. And there is also the electric thermal simulator which displays very precise plots of several signals describing the behavior of the device versus a given load. Let's see an example of electric thermal simulator. So I start with load block settings and then I check the motors parameter like armature resistance, inductance as well as its mechanical parameters. So then I go to the device, the selected H-Bridges which in this case is a VNH7040 AY. I go through the parameters and for example I check here the PCB characteristics. And finally I can start my simulation. So I check the plot and I wait just a few seconds so that the simulation is already in progress. And then I wait until the curves are plotted. I change the color of the load current curve to make it more visible. And as the fault you can see the values of the current and on the top you can see four junction temperatures of the power MOS inside. This is a typical display of a motor starting with the typical air rush phase which lasts several milliseconds. You can see that I get a time-based range of several hundreds of milliseconds. These of course can be fine-tuned until we do not see a steady state condition. The Twister Sync can be downloaded for free on www.st.com. Developers will also appreciate these tools, the two application nodes, on the standard H-Bridges, on the VNHD7 series, a comprehensive brochure and finally the VA power finder. This is a brand new mobile app available for Android and iOS that lets you explore the STVA power product portfolio on your smartphone or tablet. It has many useful features like smart, parametric search, access to main product specifications, on and offline consulting, add to favourites on the selected products and data sheets and ability to share technical documentation via social media or email. Thank you all very much for your attention. I invite you exploring our wide range of H-Bridges on www.st.com. See you soon!
