DRV8243HQDGQRQ1

Overview

The DRV8243HQDGQRQ1 is an automotive-grade half-bridge driver from Texas Instruments, designed for high-current applications. It features a supply voltage range of 4.5 V to 35 V and delivers up to 12 A output current. The device operates within a temperature range of -40°C to +150°C and utilizes an HVSSOP package. It supports SMD/SMT mounting and includes humidity sensitivity classification.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Integrated full control and power stage architecture
• High thermal performance supporting extended operating temperatures

Applications

• Automotive motor control systems
• Brushed DC motor driving
• General industrial motion control

Procurement Notes

Verify the specific suffix DGQRQ1 to confirm the HVSSOP package and reel packaging configuration. Ensure compatibility with automotive environmental requirements by checking the AEC-Q100 certification status. Confirm that the 12A current rating aligns with the thermal management design of the target application board.

Selection Notes

Select this component when a robust, automotive-certified solution is required for driving brushed DC motors or similar loads. The integrated design simplifies circuit complexity by combining control logic with power stages. Consider the HVSSOP package constraints for PCB layout and thermal dissipation strategies in space-constrained automotive environments.

Part Context
