Product Introduction

Overview

The DRV3245AQPHPRQ1 is a three-phase automotive gate driver unit developed by Texas Instruments. This device is designed for three-phase motor-drive applications and complies with the applicable requirements of ISO 26262 for functional safety, making it suitable for applications up to ASIL D. It features three half-bridge drivers capable of driving high-side and low-side N-channel MOSFETs, along with sophisticated protection and monitoring mechanisms. The device includes a charge-pump driver that supports 100% duty cycle and operates efficiently during low battery voltages, such as during cold-crank conditions.

The DRV3245AQPHPRQ1 integrates current-sense amplifiers, phase comparators, and SPI-based configuration, which reduces the bill of materials (BOM) and the space required on the printed circuit board (PCB). It also includes various protection features and diagnostic capabilities, making it a robust solution for automotive motor control systems.
