DRV8701 - Brushed DC Motor Full-Bridge Gate Driver

Description

The DRV8701 is a single H-bridge gate driver that uses four external N-channel MOSFETs targeted to drive a 12-V to 24-V bidirectional brushed DC motor.

A PH/EN (DRV8701E) or PWM (DRV8701P) interface allows simple interfacing to controller circuits.

Features

  • 1 Single H-Bridge Gate Driver.
  • Drives Four External N-Channel MOSFETs.
  • Supports 100% PWM Duty Cycle.
  • 5.9-V to 45-V Operating Supply Voltage Range.
  • Two Control Interface Options.
  • PH/EN (DRV8701E).
  • PWM (DRV8701P).
  • Adjustable Gate Drive (5 Levels).
  • 6-mA to 150-mA Source Current.
  • 12.5-mA to 300-mA Sink Current.
  • Supports 1.8-V, 3.3-V, and 5-V Logic Inputs.
  • Current Shunt Amplifier (20 V/V).
