DRV8805 Description
The DRV8805 provides an integrated solution for driving unipolar stepper motors. It includes four lowside drivers with overcurrent protection and provides built-in diodes to clamp turnoff transients generated by the motor windings. Indexer logic to control a unipolar stepper motor using a simple step/direction interface is also integrated.
