DRV8873HPWPT

Overview

The DRV8873HPWPT is a half-bridge motor driver manufactured by Texas Instruments, designed for driving brushed DC motors in industrial applications. It features an integrated H-bridge with four N-channel MOSFETs, supporting a supply voltage range of 4.5V to 38V and delivering up to 10A peak current. The device operates within a temperature range of -40°C to +125°C and utilizes a 24-pin HTSSOP PowerPAD package. Control interfaces include PH/EN or PWM modes, allowing flexible integration with controller circuits.

Feature Summary

• Integrates a full H-bridge driver with control and power stages using N-channel MOSFETs
• Provides current mirror capability for load current monitoring without high-power resistors
• Includes comprehensive protection mechanisms such as overcurrent, short circuit, and thermal shutdown
• Supports low-power sleep mode for reduced static current consumption

Applications

• Industrial brushed DC motor control
• Electronic throttle control systems
• Exhaust gas recirculation actuators
• Side mirror tilt mechanisms

Procurement Notes

Verify the specific suffix HPWPT against the official datasheet to confirm the package type and tape/reel specifications. Confirm component status as active or obsolete through authorized channels. Ensure compatibility with required logic voltage levels and thermal management solutions for the target application environment.

Selection Notes

Select this component for applications requiring bidirectional drive of brushed DC motors or single windings of stepper motors. It is suitable where space constraints favor the compact 24-HTSSOP package. Consider the integrated protection features and current sensing capabilities when designing systems that require robust fault handling and monitoring without external discrete components.

Part Context

This part belongs to the DRV8873 family of half-bridge motor drivers from Texas Instruments. The family includes automotive-grade variants like the DRV8873-Q1, which meets AEC-Q100 standards. The DRV8873 series is designed to replace discrete MOSFET solutions, offering a simplified design process for motor control applications in both industrial and automotive sectors.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the DRV8873 family. Verify if automotive-grade versions like DRV8873-Q1 are required for specific environmental certifications. Check for updated revisions or end-of-life notices before finalizing procurement decisions.
