DRV3201-Q1
SLVSBD6D – MAY 2012 – REVISED AUGUST 2015
7.1 Overview
The DRV3201-Q1 is designed to control 3 phase brushless DC motors in automotive applications using pulse
width modulation. Three high-side and three low-side gate-drivers can be switched individually with low
propagation delay. The input logic prevents simultaneous activation of high and low-side driver of the same
channel. A configuration and status register can be accessed through the SPI communication interface.
