DRV8805PWP

DRIVER, MOTOR, 4 CH, 1A/2A, 16HTSSOP.

The DRV8805PWP is a 2A unipolar stepper Motor Driver with on-chip indexer. It includes four low side drivers with over-current protection and provides built-in diodes to clamp turn-off transients generated by the motor windings. Indexer logic to control a unipolar stepper motor using a simple step/direction interface is also integrated. The DRV8805 can supply up to 2A (one channel on) continuous output current per channel, at 25°C with proper PCB heat-sinking. Internal shutdown functions are provided for over-current protection, short-circuit protection, under-voltage lockout and over-temperature and faults are indicated by a fault output pin.
