Product Introduction

Overview

The DRV8701PRGER, produced by Texas Instruments, is a single H-bridge gate driver designed to efficiently drive bidirectional brushed DC motors within a 12-V to 24-V range. This device uses four external N-channel MOSFETs and offers flexible control options through either PH/EN or PWM interfaces, making it suitable for integration with various controller circuits. The DRV8701PRGER includes an internal sense amplifier for adjustable current control and employs fixed off-time PWM current chopping to regulate the winding current, ensuring smooth motor operation.
