DRV3901-Q1EVM User's Guide

This document is the user's manual for the DRV3901-Q1 evaluation module (EVM) and the GUI to control the

EVM. The DRV3901 is a fully integrated device for driving a pyro-fuse initiator in a 12V automotive system. The

EVM showcases two DRV3901-Q1 devices for flexibility in testing parallel or redundant systems. The device

supports an input voltage up to 28V and runs on a logic supply voltage of 5.0V.
