DRV8873SPWPT

Overview

The DRV8873SPWPT is a half-bridge motor driver from Texas Instruments, packaged in a 24-pin HTSSOP PowerPAD. It supports a supply voltage range of 4.5 V to 38 V and delivers up to 10 A peak current. The device operates within a temperature range of -40°C to +125°C. It features an SPI interface for configuration and monitoring, alongside hardware control options. The component includes integrated protection mechanisms such as overcurrent, short-circuit, and thermal shutdown.

Feature Summary

• Integrates four N-channel MOSFETs to drive brushed DC motors or solenoid loads bidirectionally
• Provides current mirror output for load current monitoring without external high-power resistors
• Supports configurable control interfaces including PH/EN, PWM, and independent half-bridge modes
• Includes comprehensive protection features like UVLO, OCP, and open-load detection

Applications

• Electronic throttle control systems
• Exhaust gas recirculation actuators
• Side mirror tilt mechanisms
• Electronic shifter applications
• Airflow diverter valve control

Procurement Notes

Verify the specific suffix 'PWP' confirms the HTSSOP-24 package variant. Confirm end-of-life status with the manufacturer prior to design finalization. Ensure compatibility with existing PCB footprints and reflow profiles. Validate that the discontinued status does not impact long-term production requirements.

Selection Notes

Select this component for applications requiring integrated current sensing and robust protection in a compact form factor. Consider the SPI interface for advanced diagnostic capabilities. Evaluate the 10 A peak capability against steady-state load requirements. Verify logic input voltage compatibility with the host controller.

Part Context

This part belongs to the DRV8873 family of half-bridge motor drivers designed for industrial and automotive environments. It serves as an integrated solution for controlling single-phase loads. The device simplifies system design by combining power stages with control logic and protection circuits in a single IC.

Replacement Considerations

DRV8873SPWPR is a parameter-equivalent alternative within the same product line.
