The DRV8711 device is a stepper motor controller 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
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 (torque), step mode,
decay mode, and stall detection functions are all programmable through a SPI serial
Internal shutdown functions are provided for overcurrent protection, short-circuit
protection, undervoltage lockout, and overtemperature. Fault conditions are indicated through a
FAULTn pin, and each fault condition is reported through a dedicated bit through SPI.
The DRV8711 is packaged in a PowerPAD™
38-pin HTSSOP package with thermal pad (Eco-friendly: RoHS and no Sb/Br).
