TI DRV8873SPWPR

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.
