Overview
The DRV8143HQRXYRQ1 is an automotive-grade half-bridge driver from Texas Instruments, designed for high-current motor and ignition applications. It features a single output capable of delivering up to 20 A of continuous current. The device operates within a supply voltage range of 4.5 V to 40 V and supports switching frequencies up to 125 kHz. It is housed in a compact VQFN-14 surface-mount package and is qualified for operation across an extended temperature range from -40°C to +125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
- High-current half-bridge architecture supporting demanding motor drive loads
- Integrated protection mechanisms including overcurrent and thermal shutdown
Applications
- Automotive fuel injection systems
- Solenoid control circuits
- General automotive motor actuation
Procurement Notes
Verify the specific suffix 'HQRXYR' against the official datasheet to confirm pinout, thermal pad configuration, and tape-and-reel specifications. Ensure the component meets the required AEC-Q100 grade for your target automotive application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single high-current channel is required for automotive loads. Compare against the DRV8143SQRXYRQ1 if different packaging or minor parameter variations are needed. Consider the DRV8243 series for lower current requirements or H-bridge configurations. Evaluate thermal management solutions based on the 20 A output capability and VQFN-14 package constraints.
Part Context
This part belongs to the DRV8143 family of automotive half-bridge drivers. It shares functional similarities with other members like the DRV8143SQRXYRQ1 but differs in specific package or ordering details. The family targets robust control of inductive loads in harsh automotive environments, providing a standardized interface for engine management and chassis systems.
Replacement Considerations
The DRV8143SQRXYRQ1 is a related variant within the same product family. Verify pin compatibility and electrical specifications before substitution. No other direct cross-model replacements are confirmed in the provided documentation.
