DRV8802PWPR

Overview

The DRV8802PWPR is an automotive-grade dual half-bridge brushed DC motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 8 V to 45 V and delivers up to 1.6 A output current per channel. The device integrates power MOSFETs in a 28-pin HTSSOP package with exposed thermal pad for efficient heat dissipation. It meets AEC-Q100 Grade 1 qualification standards, ensuring reliability in harsh environments. The operational junction temperature range extends from -40°C to +150°C, supporting demanding industrial and automotive applications.

Feature Summary

• Integrated dual half-bridge architecture with built-in power MOSFETs for compact design
• Automotive qualification compliant with AEC-Q100 standards for enhanced durability
• Wide operating voltage range accommodating various system power supplies
• High thermal performance capability with extended junction temperature rating

Applications

• Automotive seat adjustment actuators
• Power window and sunroof drive systems
• Electronic parking brake mechanisms
• Thermal management fan control in vehicles

Procurement Notes

Verify the specific suffix PWPR corresponds to the HTSSOP-28 package and reel packaging configuration required for your assembly process. Confirm that the Q1 designation indicates AEC-Q100 automotive grade compliance suitable for your vehicle's environmental specifications. Ensure input voltage levels remain within the 8 V to 45 V operational limits during all system states.

Selection Notes

Select this component when dual independent brushed DC motor control is required in space-constrained automotive designs. The integrated MOSFET structure reduces external component count compared to discrete solutions. Consider the thermal requirements of the HTSSOP package if driving currents approach the maximum rated limit continuously.

Part Context

This part belongs to the DRV8802 family of dual half-bridge drivers designed specifically for automotive markets. It serves as a robust solution for controlling multiple low-power brushed motors in vehicle subsystems. The integration of control logic and power stages simplifies PCB layout and improves system reliability compared to multi-component approaches.

Replacement Considerations

Check for direct pin-compatible alternatives within the DRV88xx series that may offer different current ratings or package options. Verify functional equivalence regarding control interface signals and protection features before substitution.
