The DRV8849 is a dual stepper motor driver for industrial and consumer applications. The device is fully integrated with four N-channel power MOSFET H-bridge drivers, one microstepping indexer for each stepper, and integrated current sensing. The DRV8849 is capable of driving up to 1.5-A (limited by board design). The DRV8849 uses STEP/DIR interface to control the direction and step rate of the stepper motor.

Protection features are provided for supply undervoltage, charge pump faults, overcurrent, short circuits, and overtemperature.
