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 DRV8824 is capable of driving up to 1.6 A of current from each output (with proper heatsinking, at 24 V and 25°C). A simple STEP/DIR interface allows easy interfacing to controller circuits.
