Description

The DRV8873device is an integrated driver IC for driving a brushed DC motor in industrial applications. Two logicinputs control the H-bridge driver, which consists of four N-channel MOSFETs that drive motorsbi-directionally with up to 10-A peak current. The device operates from a single power supply andsupports 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 mirrorapproximates the current through the high-side FETs, and does not require a high-power resistor forsensing the current.

A low-power sleep mode is provided to achieve very-low quiescent current draw by shuttingdown much of the internal circuitry. Internal protection functions are provided for undervoltagelockout, charge pump faults, overcurrent protection, short-circuit protection, open-load detection,and overtemperature. Fault conditions are indicated on an nFAULT pin and through the SPIregisters.
