DRV8242HQRHLRQ1

Overview

The DRV8242HQRHLRQ1 is an automotive-grade H-bridge driver from Texas Instruments, designed for high-current applications. It supports a supply voltage up to 40 V and delivers a continuous output current of 6 A per channel. The device integrates smart gate drive technology with optimized switching characteristics to minimize electromagnetic interference (EMI). Key electrical parameters include a maximum operating temperature of +150 °C and a minimum operating temperature of -40 °C. It features integrated protection mechanisms such as overcurrent protection, thermal shutdown, and undervoltage lockout to ensure reliable operation in harsh automotive environments.

Feature Summary

• Integrates smart gate drive technology with optimized switching characteristics to minimize electromagnetic interference.
• Provides robust protection against overcurrent conditions, excessive temperatures, and low supply voltages.
• Supports high-temperature operation suitable for demanding automotive under-hood environments.

Applications

• Automotive seat actuators
• Automotive window lifters
• Automotive mirror adjustment systems

Procurement Notes

Verify the specific suffix 'HQRHLRQ1' against the manufacturer's official datasheet to confirm package type, tape-and-reel specifications, and automotive qualification status. Ensure that the ordering information matches the exact component marking and pinout requirements for your design. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when designing motor control circuits requiring a single H-bridge capable of driving loads up to 6 A at 40 V. Consider its integrated EMI reduction features if strict electromagnetic compatibility standards must be met without external filtering components. Evaluate the thermal performance and heat dissipation requirements based on the expected duty cycle and ambient temperature conditions in the target application.

Part Context

This part belongs to the DRV824x family of automotive H-bridge drivers from Texas Instruments. The family is characterized by high current capability and integrated protection features tailored for automotive reliability. The DRV8242 variant specifically offers 6 A per channel, distinguishing it from lower or higher current counterparts within the same product line.

Replacement Considerations

Consult the official datasheet for direct cross-reference recommendations. Potential substitutes may include other models within the DRV824x series or compatible H-bridge drivers from the same manufacturer, provided they meet the voltage, current, and interface requirements.
