Overview
The DRV8711DCP from Texas Instruments is a sophisticated stepper motor controller designed to drive bipolar stepper motors or two brushed DC motors. This device integrates a 1/256 microstepping indexer, enabling smooth motion profiles with various current decay modes, including an automatic mixed decay mode. It operates within an 8-V to 52-V supply voltage range and features a highly configurable SPI serial interface for programming device operations. The DRV8711DCP also includes protection and diagnostic features such as overcurrent protection, overtemperature shutdown, undervoltage lockout, and individual fault condition indication bits.
