EV-VNH90xxAQ motor driver
Introduction
This document describes the specifications for the EV-VNH90xxAQ easy board, which can be connected to the EV-SPC582B to
create a full bridge motor driver evaluation tool intended for a wide range of automotive applications. To simplify the evaluation
of VNH90xxAQ devices, a GUI has been developed to facilitate the management of VNH90xxAQ inputs, monitor H-Bridge
status, and provide current sensing and fault diagnostic feedback. Collectively, this solution provides a powerful and flexible tool
for managing motor operations.
