INA284AQDGKRQ1

Current Regulation/Management Overview

The INA284AQDGKRQ1 is an automotive-grade bidirectional current shunt monitor manufactured by Texas Instruments. It features a wide common-mode voltage range of -14V to 80V, allowing for high-side or low-side sensing applications. The device offers a typical accuracy of ±0.4% and operates within an extended temperature range of -40°C to 125°C. Packaged in an 8-VSSOP surface-mount case, it is AEC-Q100 qualified for robust performance in demanding automotive environments.

Current Regulation/Management Feature Summary

• Bidirectional current sensing capability supporting both high-side and low-side configurations
• High precision with ±0.4% accuracy for reliable measurement
• Wide common-mode voltage range from -14V to 80V
• Automotive qualification under AEC-Q100 standards

Current Regulation/Management Applications

• Automotive battery management systems
• Electric vehicle charging infrastructure monitoring
• Motor control current sensing
• General automotive power distribution monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix 'RQ1' confirms the reel packaging and automotive grade status. Ensure compatibility with the 8-VSSOP footprint during PCB layout. Confirm that the -14V to 80V common-mode range aligns with the target circuit's voltage levels. Check for RoHS3 compliance requirements if applicable to the final assembly process.

Current Regulation/Management Selection Notes

Select this component when bidirectional sensing is required alongside high accuracy in automotive settings. The ±0.4% error margin suits precise energy metering tasks. Consider the 8-VSSOP package for space-constrained designs. Compare against non-automotive variants if cost is critical but reliability standards are less stringent.

Current Regulation/Management Part Context

This part belongs to the INA28x-Q1 family of bidirectional current shunt monitors designed for automotive use. It complements other Texas Instruments solutions like the INA200 series, which offers different accuracy levels. The Q1 designation indicates adherence to automotive quality and reliability standards, distinguishing it from commercial-grade counterparts.

Current Regulation/Management Replacement Considerations

INA284AIDGKR is the commercial-grade equivalent without automotive qualification. INA200AQDGKRQ1 provides similar form factor but lower accuracy at ±3.5%. Verify pinout compatibility before substitution. Ensure thermal and electrical ratings meet system requirements when swapping between these variants.
