DRV8873HPWPR

DRV8873HPWPR Description

The DRV8873HPWPR from Texas Instruments is a high-performance NMOS-based brushed DC motor driver designed for industrial applications. This 24-pin HTSSOP-packaged IC integrates a dual half-bridge (2x Half Bridge) output configuration, supporting load voltages from 4.5V to 38V and delivering up to 10A continuous output current. With a wide supply voltage range (0V to 5.5V), it offers robust control for brushed DC and unipolar stepper motors. The device features hardware-based interface control, ensuring deterministic operation without firmware dependencies. Its REACH unaffected and ROHS3-compliant construction aligns with environmental standards, while the MSL 3 (168-hour) moisture sensitivity rating ensures reliability in industrial environments.
