Overview
The DRV8143HQDGQRQ1 is an automotive-grade half-bridge driver from Texas Instruments, designed for high-current motor and ignition applications. It features a wide supply voltage range of 4.5 V to 40 V and delivers a continuous output current of 20 A. The device operates reliably within an extended temperature range from -40°C to +125°C. Packaged in a compact HVSSOP format, it integrates protection mechanisms suitable for harsh automotive environments.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability
- High current capability supporting demanding motor drive loads
- Integrated protection against overcurrent and thermal stress conditions
Applications
- Automotive fuel injection systems
- Solenoid control circuits
- High-power valve actuation
Procurement Notes
Verify the specific suffix 'HQDGQRQ1' to ensure correct package type and automotive grade alignment. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications and manufacturing processes.
Selection Notes
Select this component when a single half-bridge configuration with 20 A capacity is required. Ensure the system voltage does not exceed 40 V. Consider the HVSSOP package constraints for thermal management and PCB layout. Verify that the operating temperature range meets the specific environmental demands of the target application.
Part Context
This part belongs to the DRV8143 family of automotive half-bridge drivers. It shares functional similarities with other members like DRV8143HQRXYRQ1 but differs in package and specific pinout configurations. The series is optimized for robust performance in electric and hybrid vehicle powertrains.
Replacement Considerations
DRV8143HQRXYRQ1 offers similar electrical characteristics but utilizes a VQFN package instead of HVSSOP. Verify pin-to-pin compatibility and thermal dissipation requirements before substitution.
