Overview
The DRV8243SQRXYRQ1 is an automotive-grade H-bridge driver from Texas Instruments, designed for robust motor control applications. It features a 40-V supply voltage range and delivers a continuous output current of 12 A. The device integrates high-side and low-side N-channel power MOSFETs with integrated current sensing and feedback capabilities. Operating within a temperature range of -40°C to +125°C, it utilizes a 14-pin VQFN-HR package (3x4.5 mm) suitable for surface mount installation. The component supports PWM and SPI interfaces for precise control.
Feature Summary
- Integrated current sensing and feedback mechanism for accurate load monitoring
- Automotive qualification ensuring reliability in harsh operating environments
- Compact VQFN-HR package design facilitating efficient thermal management
Applications
- Automotive seat adjustment motors
- Power window and sunroof actuators
- Throttle body control systems
Procurement Notes
Verify the specific suffix 'SQRXYR' against the official Texas Instruments datasheet to confirm pinout, packaging variant, and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the ordering part number with TI's official distribution channels to avoid counterfeit components. Confirm that the automotive grade designation meets your system's functional safety standards.
Selection Notes
Select this component when a single H-bridge configuration with integrated current sense is required for automotive loads up to 12 A. It is suitable for applications needing compact footprints and high thermal performance. Consider alternative DRV824x-Q1 variants if different current ratings or interface options are needed. Evaluate thermal dissipation needs based on the VQFN-HR package limitations under continuous load conditions.
Part Context
This part belongs to the DRV824x-Q1 family of fully integrated H-bridge drivers intended for wide-ranging automotive applications. The family shares common architectural features but varies in current ratings and packaging. The DRV8243-Q1 specifically targets mid-power motor control tasks, offering a balance between performance and integration level compared to higher-current counterparts in the same series.
Replacement Considerations
Direct substitutes within the DRV824x-Q1 family include DRV8243HQRXYRQ1 and DRV8243PQDGQRQ1, provided pinouts and electrical characteristics match the design requirements. Verify package dimensions and thermal properties before substitution.
