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 devices also provides a low-power sleep function. The motor drivers provide PWM current control capability. The current is programmable, based on an externally suppli...
