Product Introduction

Overview

The DRV8323SRTAR is a three-phase smart gate driver designed by Texas Instruments for high-performance applications, particularly in driving brushless DC (BLDC) motors and other three-phase systems. This device integrates three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. It features an advanced smart gate drive architecture with adjustable slew rate control, integrated gate driver power supplies, and optional integrated buck regulators and current sense amplifiers.
