描述

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 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.

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.

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.
