DRV8243PQDGQRQ1

Overview

The DRV8243PQDGQRQ1 is an automotive-grade H-bridge motor driver manufactured by Texas Instruments. It supports a supply voltage range of 4.5 V to 35 V and delivers a continuous output current of 12 A per channel. The device operates within a temperature range of -40°C to +125°C and utilizes an HVSSOP-28 package. It features a 25 kHz operating frequency and draws a typical quiescent current of 10 mA. Designed for robust performance, it meets AEC-Q100 standards for automotive applications.

Feature Summary

• Integrated full H-bridge configuration with built-in control and power stages
• Automotive qualification compliant with AEC-Q100 standards
• Supports operation in harsh environments up to 125°C junction temperature

Applications

• Automotive seat adjustment systems
• Power window actuators
• Sunroof and convertible top drives
• Electronic parking brake mechanisms

Procurement Notes

Verify the complete part number including the PQDGQRQ1 suffix to ensure correct packaging and automotive grade specification. Confirm that the design accounts for the specified thermal requirements given the 12 A current capability. Ensure compatibility with the 4.5 V to 35 V supply rail before integration. Check for moisture sensitivity level handling during assembly.

Selection Notes

Select this component when a single-chip solution for bidirectional motor control is required in space-constrained automotive designs. The HVSSOP-28 package offers a balance between thermal dissipation and board area. Consider the 12 A rating against peak load demands to avoid derating issues. Verify interface compatibility if additional logic control is needed beyond basic drive signals.

Part Context

This device belongs to the DRV8243-Q1 family of high-current H-bridge drivers designed specifically for automotive markets. It integrates gate drivers and power MOSFETs into a single compact package. The series targets applications requiring reliable motor actuation under varying electrical and thermal conditions typical in modern vehicles.

Replacement Considerations

The DRV8243HQDGQRQ1 is listed as a parameter-equivalent alternative from Texas Instruments. Verify pinout and thermal characteristics match before substitution.
