DRV8873 H-Bridge Motor Driver

1 Features

3 Description

The DRV8873 device is an integrated driver IC for

driving a brushed DC motor in industrial applications.

Two logic inputs control the H-bridge driver, which

consists of four N-channel MOSFETs that drive

motors bi-directionally with up to 10-A peak current.

The device operates from a single power supply and

supports a wide input supply range from 4.5 V to 38

Drives One DC Motor, One Winding of a

Stepper Motor, or Solenoid Loads

•

4.5-V to 38-V Operating Voltage Range

10-A Peak Current Drive

Low HS + LS R_DS(ON)

–

150 mΩ at T_J= 25°C, 13.5 V

250 mΩ at T_J= 150°C, 13.5 V

A PH/EN or PWM interface allows simple interfacing

to controller circuits. Alternatively, independent half-

bridge control is available to drive two solenoid loads.

•

Current Mirror for Output Current Sensing

Configurable Control Interface

A current mirror allows the controller to monitor the

load current. This mirror approximates the current

through the high-side FETs, and does not require a

high-power resistor for sensing the current.

PH/EN

PWM (IN1/IN2)

Independent Half-Bridge Control

A low-power sleep mode is provided to achieve very-

low quiescent current draw by shutting down much of

the internal circuitry. Internal protection functions are

provided for undervoltage lockout, charge pump

faults, overcurrent protection, short-circuit protection,

open-load detection, and overtemperature. Fault

conditions are indicated on an nFAULT pin and

through the SPI registers.
