The DRV8805PWP is a unipolar stepper motor driver IC designed for driving unipolar stepper motors with an integrated indexer for simplified control. It features four low-side NMOS FET drivers with overcurrent protection and built-in inductive clamp diodes to manage turn-off transients. The device supports a supply voltage range of 8.2 V to 60 V and can deliver a maximum continuous output current of 2 A per channel when one channel is active, or 1 A per channel when all four channels are active, provided proper PCB heatsinking is implemented. The DRV8805PWP offers three stepping modes: 2-phase full-step, 1-2-phase half-step, and 1-phase wave drive, allowing for flexible motor control. It is housed in a thermally enhanced 16-pin HTSSOP package, which includes an exposed PowerPAD for improved thermal management. The device also incorporates internal shutdown features for overcurrent, short-circuit, under-voltage lockout, and overtemperature conditions, with fault status indicated via a dedicated output pin. This product is suitable for applications such as gaming machines and general unipolar stepper motor driving tasks.
