The DRV8823DCA is a 4-bridge serial interface Motor Driver for printers and other office automation equipment applications. The motor driver circuit includes four H-bridge drivers. Each of the motor driver blocks employ N-channel power MOSFETs configured as an H-bridge to drive the motor windings. A simple serial interface allows control of all functions of the motor driver with only a few digital signals. The device also provides a low-power sleep function. The motor drivers provide PWM current control capability. The current is programmable, based on an externally supplied reference voltage and an external current sense resistor. In addition, eight current levels (set through the serial interface) allow microstepping with bipolar stepper motors. Internal shutdown functions are provided for overcurrent protection (OCP), short-circuit protection, under-voltage lockout and over-temperature.
