DRV8711 Description

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. The motor stall is reported with an optional back-EMF output. The DRV8711 is packaged in a PowerPAD? 38-pin HTSSOP package with a thermal pad (Eco-friendly: RoHS and no Sb/Br).
