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.

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.

The STEVAL-IFP022V1 demonstration board

meets EFT standard requirements IEC 61000-4-

2, IEC 61000-4-4, IEC 61000-4-5.
