DRV8873HPWPR

Overview

The DRV8873HPWPR is a fully integrated H-bridge motor driver IC manufactured by Texas Instruments, designed for driving brushed DC motors, stepper motor windings, and solenoid loads in industrial applications. It features two half-bridges controlled by logic inputs, utilizing four N-channel MOSFETs to deliver up to 10A peak current. The device operates on a single supply voltage ranging from 4.5V to 38V, with a control supply range of 0V to 5.5V. It supports PH/EN or PWM interfaces and includes an internal current mirror for load monitoring without external sense resistors. Packaged in a 24-HTSSOP PowerPAD™, it offers comprehensive protection including overcurrent, short-circuit, and thermal shutdown.

Feature Summary

• Integrated H-bridge architecture with four N-channel MOSFETs enabling bidirectional drive for motors and solenoids.
• Internal current mirror allows precise load current monitoring without requiring high-power external sense resistors.
• Configurable control interface supporting PH/EN, PWM, or independent half-bridge modes for flexible system integration.
• Comprehensive protection suite including UVLO, OCP, short-circuit detection, open-load detection, and thermal shutdown.

Applications

• Electronic throttle control systems
• Industrial automation and robotics actuators
• Solenoid and valve control in manufacturing equipment

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the industrial temperature grade (-40°C to +125°C) aligns with the operational environment specifications. Ensure compatibility with the intended controller logic levels (1.8V, 3.3V, or 5V) before finalizing component selection.

Selection Notes

Select this component when a robust, high-current solution is needed for brushed DC motors or solenoids in industrial settings. The integrated current sensing simplifies design by eliminating external shunt resistors. Consider the 24-pin HTSSOP package constraints for thermal management and PCB layout. This part is suitable for applications requiring reliable protection features against electrical faults and overheating.

Part Context

The DRV8873HPWPR belongs to the DRV8873 family of H-bridge motor drivers from Texas Instruments. It is specifically the industrial-grade variant packaged in a 24-HTSSOP with a PowerPAD for enhanced thermal dissipation. Unlike automotive-qualified versions (DRV8873-Q1), this part is optimized for general industrial applications while maintaining high performance and reliability standards for demanding electromechanical control tasks.

Replacement Considerations

Direct pin-to-pin replacements within the same family include DRV8873SPWPR for standard performance variants. For automotive applications, consider DRV8873HPWPRQ1 if AEC-Q100 qualification is required. Verify that any substitute maintains the 10A peak current capability and compatible control interface options.
