STEVAL-IFP022V1

STEVAL-IFP022V1 Eight-channel high-side driver based on the VNI8200XP Data brief As required by industrial standards, 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 (part number STEVAL-PCC009V2). 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. Features • Operating voltage: from 10.5 to 33 V • Operating current: 0.7 A for each channel • Reverse polarity protection • High-speed opto-isolation for SPI and parallel communication The STEVAL-IFP022V1 demonstration board meets EFT standard requirements IEC 61000-42, IEC 61000-4-4, IEC 61000-4-5. • Low-speed opto-isolation for device fault signaling • Step-down converter for 3.3 V or 5 V • Digital supply voltage • LED matrix for channel status signaling • Microcontroller interface • Designed to meet EMC standard requirements: IEC 61000-4-2, IEC 61000-4-4, IEC 61000-4-5 • RoHS compliant Description 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.
