1 Introduction

DRV3901-Q1
WARNING: The evaluation module (EVM) has a fuse rated for 20 A. Please confirm that the maximum current draw of the battery voltage supply is always less than 20 A to prevent the fuse from activating.

The DRV3901-Q1 is a fully integrated device for driving a pyro-fuse initiator in a 12-V automotive system. The DRV3901-Q1 has multiple-diagnostic and protection features (over-current protection, over-temperature shutdown, under voltage, and more) that protect the IC and check the availability of the deployment function.
