DRV401AIRGWR

Sensor And Detector Interfaces Overview

The DRV401AIRGWR is a Texas Instruments sensor interface integrated circuit designed for magnetic current sensing applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features an internal 2.5 V reference voltage. The device utilizes a 4-wire SPI serial interface for communication. It is housed in a 20-pin VQFN package with dimensions suitable for surface-mount technology. The component supports an operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments. It functions as an analog front-end (AFE) specifically optimized for conditioning signals from magnetic sensors.

Sensor And Detector Interfaces Feature Summary

• Integrated analog front-end architecture tailored for magnetic current sensing signal conditioning
• Digital output capability via standard 4-wire serial peripheral interface (SPI)
• High-temperature operational stability supporting industrial and automotive thermal profiles

Sensor And Detector Interfaces Applications

• Magnetic current sensing systems requiring isolated or non-contact measurement
• Industrial motor control circuits utilizing Hall-effect or magnetoresistive sensors
• Automotive power management and monitoring subsystems

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'GWR' corresponds to the VQFN-20 package and reel packaging configuration when sourcing. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure design compatibility with the required 4.5 V to 5.5 V supply rails and SPI protocol timing specifications.

Sensor And Detector Interfaces Selection Notes

Select this component when a dedicated analog front-end for magnetic sensors is required alongside digital connectivity. Compare against the DRV401AIDWPR if a HSOP-20 package is preferred instead of the VQFN form factor. Consider the broader DRV401 family variants if different pinouts or additional driver capabilities are needed for the specific application topology.

Sensor And Detector Interfaces Part Context

This part belongs to the DRV401 series of sensor signal conditioners manufactured by Texas Instruments. The series focuses on providing precise signal conditioning for magnetic current sensing applications. The AIRGWR variant specifically denotes the automotive-grade qualification and the VQFN-20 surface-mount package type within this product line.

Sensor And Detector Interfaces Replacement Considerations

The DRV401AIRGWTG4 is listed as a discontinued version of this component. The DRV401AIRGWR serves as the recommended manufacturer replacement for the older G4 suffix variant. Verify pinout compatibility and package dimensions before substituting.
