The Texas Instruments DRV8711DCPR is a stepper motor controller IC that pairs with external N-channel MOSFETs to drive a bipolar stepper or two brushed DC motors. It offers a built-in microstepping indexer resolving down to 1/256 step, SPI-programmable torque and decay modes, plus BEMF-based stall detection. The 38-pin HTSSOP device operates over an 8 V to 52 V supply.

FAQ
What microstepping resolution does the DRV8711DCPR provide?
Its built-in indexer supports up to 1/256 microstepping, selectable over the SPI interface for smoother and quieter motor motion.
Can the DRV8711DCPR drive DC motors as well as steppers?
Yes, by using PWM control mode the same device can drive two brushed DC motors in addition to a bipolar stepper motor.
