Product Introduction
The DRV8873-Q1 device is an integrated driver IC for driving brushed DC motors in automotive applications. Two logic inputs control the H-bridge driver, which includes four N-channel MOSFETs capable of bidirectionally driving the motor with a peak current of up to 10A. The device is powered by a single supply and supports a wide input power supply range from 4.5V to 38V. The device can be easily connected to the controller circuit through a PH/EN or PWM interface. Alternatively, independent half-bridge control can be used to drive two solenoid loads. The controller can utilize a current mirror to monitor the load current. This current mirror approximates the current flowing through the high-side FET and does not require the use of high-power resistors for current detection. A low-power sleep mode is provided to achieve extremely low quiescent current consumption by shutting down a large amount of internal circuitry. Internal protection features for undervoltage lockout, charge pump fault, overcurrent protection, short-circuit protection, open-load detection, and overheat are also provided. Fault conditions can be indicated via the nFAULT pin and the SPI register.
