Texas Instruments DRV8804 2.0A Unipolar Stepper Motor or 1A Quad Solenoid/Relay Driver (Serial Ctrl) DRV8804PWP

The DRV8804PWP is a quad low-side driver IC designed for driving unipolar stepper motors, solenoids, and relays. It features four N-channel MOSFETs with integrated overcurrent protection and inductive clamp diodes, making it suitable for handling inductive loads. The device operates within a supply voltage range of 8.2V to 60V and can deliver a maximum continuous output current of 2A per channel when one channel is active, or 1A per channel when all four channels are active, provided proper PCB heatsinking is applied. The DRV8804PWP includes a serial interface for control, allowing multiple devices to be daisy-chained. It also incorporates internal shutdown functions for overcurrent, short-circuit, undervoltage lockout, and overtemperature protection, with fault conditions indicated by a dedicated output pin. The package is a thermally-enhanced HTSSOP, which aids in heat dissipation during operation. This product is suitable for applications requiring reliable control of motors and solenoids in various electronic systems.
