The DRV8711DCP is a stepper motor Gate Driver with on-chip 1/256 micro-stepping indexer and stall detect that uses external N-channel MOSFETs to drive a bipolar stepper motor or two brushed DC motors. A microstepping indexer is integrated, which is capable of step modes from full step to 1/256-step. An ultra-smooth motion profile can be achieved using adaptive blanking time and various current decay modes, including an auto-mixed decay mode. Motor stall is reported with an optional back-EMF output. A simple step/direction or PWM interface allows easy interfacing to controller circuits. A SPI serial interface is used to program the device operation. Output current, step mode, decay mode and stall detection functions are all programmable through a SPI serial interface. Internal shutdown functions are provided for over-current protection, short-circuit protection, under-voltage lockout and over-temperature.
