Product Introduction

Overview

The DRV8701ERGET from Texas Instruments is a single H-bridge gate driver designed to drive 12-V to 24-V bidirectional brushed DC motors using four external N-channel MOSFETs. This device offers a simple interface to controller circuits through either a PH/EN (DRV8701E) or PWM (DRV8701P) control interface. It includes an internal sense amplifier for adjustable current control and uses fixed off-time PWM current chopping to regulate the winding current. The DRV8701ERGET also features low-power sleep mode, integrated protection functions, and two LDO voltage regulators to power external components.
