DRV8243HQRXYRQ1

Overview

The DRV8243HQRXYRQ1 is an automotive-grade, fully integrated H-bridge motor driver manufactured by Texas Instruments. It supports bipolar stepper and brushed DC motors with a supply voltage range of 4.5 V to 35 V and delivers up to 12 A output current per half-bridge. The device utilizes Bi-CMOS technology and features a hardwired interface for control. It operates within a temperature range of -40°C to +125°C and is housed in a compact 14-VQFN-HR (3x4.5 mm) package with wettable flanks. The component holds AEC-Q100 qualification for automotive reliability.

Feature Summary

• Fully integrated design combining control logic and power stage for simplified implementation
• Hardwired interface enables direct connection to microcontrollers without complex communication protocols
• Wettable flank packaging facilitates visual inspection of solder joints for enhanced quality assurance

Applications

• Automotive active grille shutters
• Automotive fuel pumps
• Automotive valve actuators

Procurement Notes

Verify the specific suffix 'RXYR' confirms the 14-VQFN-HR package variant when sourcing. Ensure the component meets AEC-Q100 Grade 1 requirements for your target application environment. Confirm RoHS3 compliance status through official manufacturer documentation prior to integration into production lines.

Selection Notes

Select this model for applications requiring high current drive in a small footprint. The hardwired interface suits designs where SPI or PWM complexity is unnecessary. Compare against the DRV8243PQDGQRQ1 if a larger HVSSOP-28 package is preferred for thermal management or ease of assembly.

Part Context

This part belongs to the DRV8243-Q1 family of automotive H-bridge drivers. It shares functional similarities with other members like the DRV8243SQDGQRQ1 but differs in package type and interface. The family targets various motor control needs in vehicles, offering options for different current ratings and form factors to suit diverse mechanical constraints.

Replacement Considerations

The DRV8243HQDGQRQ1 is listed as a parameter-equivalent substitute. Verify pinout compatibility and package dimensions before substitution.
