STMicroelectronics Demonstration Board for VNI8200XP for High Side Driver

The STEVAL-IFP022V1 demonstration board is based on VNI8200XP high-side driver. It was developed as an instrument to test device functionality in terms of power management and digital interface. The board’s isolated interface between the IPS and host controller were implemented using high-speed opto-couplers for IPS driving, and low-speed opto-couplers to receive device status information. The connection is achieved through a 30-pin connector. To provide a user-friendly way to test VNI8200XP device functionality, a GUI interface was developed. To use the GUI it is necessary to connect the STEVAL-IFP022V1 demonstration board to a PC by using a communication board. Thermal performance is improved thanks to a four-layer structure which makes it possible to design a copper area distributed in all the layers for more effective heat dissipation.
