DRV8873SPWPRQ1

Overview

The DRV8873SPWPRQ1 is an automotive-grade half-bridge motor driver designed for brushed DC motors. It features a fully integrated H-bridge with four N-channel MOSFETs, delivering up to 10A peak current. The device operates on a single supply voltage ranging from 4.5V to 38V and supports logic inputs of 1.8V, 3.3V, or 5V. It offers configurable control interfaces including PH/EN, PWM, independent half-bridge control, and SPI communication. Integrated protection mechanisms include UVLO, OCP, short-circuit protection, open-load detection, and thermal shutdown.

Feature Summary

• Configurable control interface supporting PH/EN, PWM, independent half-bridge, and SPI modes
• Integrated current mirror for load current monitoring without high-power resistors
• Comprehensive protection suite including overcurrent, short-circuit, and thermal shutdown
• Low power consumption with dedicated sleep mode for minimal static current draw

Applications

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

Procurement Notes

Verify the specific suffix 'SPWPR' to confirm the package type and interface configuration (SPI) against your schematic requirements. Ensure the component meets AEC-Q100 Grade 1 standards for your target automotive temperature range. Cross-reference the manufacturer part number with official Texas Instruments documentation to validate authenticity and revision status before integration into production designs.

Selection Notes

Select this component when designing automotive brushed DC motor drives requiring SPI-based control or precise current monitoring capabilities. It is suitable for applications needing bidirectional drive and robust fault protection within a compact 24-HTSSOP PowerPAD package. Consider alternative variants if hardware-only control or different packaging constraints are required for the specific system architecture.

Part Context

This part belongs to the DRV8873 family of half-bridge motor drivers from Texas Instruments. The 'Q1' suffix indicates automotive qualification compliant with AEC-Q100 standards. The 'S' in the model number typically denotes specific interface or package variations within the series, distinguishing it from standard industrial versions like the DRV8873HPWPR.
