DRV8872DDARQ1

Overview

The DRV8872DDARQ1 is an automotive-grade, fully integrated half-bridge motor driver manufactured by Texas Instruments. Designed for brushed DC motor applications, it supports a supply voltage range of 6.8 V to 45 V and delivers a continuous output current of 3.6 A. The device features an SO-PowerPad-8 surface-mount package with an exposed thermal pad for efficient heat dissipation. It operates within a junction temperature range of -40°C to +150°C and holds AEC-Q100 qualification. The driver integrates control logic and power stages, utilizing PWM interface technology for precise motor management.

Feature Summary

• Fully integrated half-bridge architecture combining control logic and NMOS power stages
• Automotive qualification compliant with AEC-Q100 standards for reliability
• Integrated fault reporting mechanism for system diagnostics
• High thermal efficiency via SO-PowerPad-8 package design

Applications

• Brushed DC motor control in automotive systems
• General industrial motion control applications
• Ignition controller circuits

Procurement Notes

Verify the Q1 suffix confirms automotive grade status and AEC-Q100 compliance. Confirm the DDAR suffix indicates the specific SO-PowerPad-8 package variant. Ensure compatibility with 6.8V minimum supply requirements. Check datasheet for thermal derating curves at high ambient temperatures. Validate that the component meets specific vehicle manufacturer quality standards.

Selection Notes

Select this component for designs requiring robust automotive reliability and high current handling. The integrated fault reporting simplifies diagnostic implementation compared to discrete solutions. Consider the SO-PowerPad-8 package for optimal thermal performance in space-constrained layouts. Verify input voltage ranges align with the 6.8V to 45V operational window. Evaluate PCB layout guidelines for thermal pad connection to ensure adequate heat sinking.

Part Context

This part belongs to the DRV8872 family of single H-bridge drivers from Texas Instruments. It serves as the automotive-qualified counterpart to commercial variants like the DRV8872DDAR. The series focuses on providing a compact, cost-effective solution for driving medium-power brushed DC motors in demanding environments where standard consumer components may not suffice.

Replacement Considerations

The DRV8872DDAR is a commercial equivalent with identical electrical specifications but lacks automotive qualification. Verify if the application strictly requires AEC-Q100 certification before substituting.
