DRV8825 is a bipolar stepper motor driver with on-chip microstepping indexer

This post sponsored by Texas Instruments.

The DRV8825 provides an integrated motor driver solution for printers, scanners, and other automated equipment applications.  

The device has two H-bridge drivers and a microstepping indexer, and is intended to drive a bipolar stepper motor. The output driver block consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings. The DRV8825 is capable of driving up to 2.5 A of current from each output (with proper heat sinking). A simple STEP/DIR interface allows easy interfacing to controller circuits. Mode pins allow for configuration of the motor in full-step up to 1/32-step modes. Decay mode is configurable so that slow decay, fast decay, or mixed decay can be used. A low-power sleep mode is provided, which shuts down internal circuitry to achieve very low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin. Internal shutdown functions are provided for overcurrent, short circuit, under voltage lockout and over temperature. Fault conditions are indicated via the nFAULT pin. Applications: automatic teller machines, money handling machines, video security cameras, printers, scanners, office automation machines, gaming machines, robotics, etc.
