INA202AQDGKRQ1

Current Regulation/Management Overview

The INA202AQDGKRQ1 is an automotive-grade, high-side current shunt monitor manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports input common-mode voltages from -0.2 V to 80 V. The device features a fixed gain of 50 V/V with a maximum gain error of ±1% and an output swing capable of reaching the negative rail. It is qualified under AEC-Q100 standards for operation in temperatures ranging from -40°C to +125°C.

Current Regulation/Management Feature Summary

• High-side current sensing capability supporting wide common-mode voltage ranges up to 80 V
• Fixed internal gain of 50 V/V providing precise signal amplification
• Rail-to-rail output stage allowing full-scale measurement near ground potential
• Automotive qualification ensuring reliability in harsh thermal environments

Current Regulation/Management Applications

• Battery management systems in electric vehicles
• Motor control circuits requiring precise current feedback
• Load switch monitoring in automotive power distribution
• General-purpose high-side current protection schemes

Current Regulation/Management Procurement Notes

Verify the specific suffix 'RQ1' confirms AEC-Q100 automotive qualification and tape-and-reel packaging format. Ensure compatibility with your system's common-mode voltage limits before integration. Cross-reference the datasheet revision date to confirm technical specifications match your design requirements. Confirm RoHS compliance status if required by your manufacturing standards.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required with a fixed gain configuration. It is suitable for applications needing rail-to-rail output performance without external level shifting. Consider the ±1% gain accuracy for precision monitoring tasks. Evaluate the 80 V common-mode limit against peak transient voltages in your circuit design.

Current Regulation/Management Part Context

This part belongs to the INA20x-Q1 family of current shunt monitors designed for automotive applications. It shares the VSSOP-8 package form factor with other devices in the series but differs in gain settings and specific electrical characteristics. The family targets robust current monitoring solutions for electric and hybrid vehicle architectures.

Current Regulation/Management Replacement Considerations

Check for direct pin-compatible alternatives within the INA20x-Q1 series that offer different gain factors. Verify that any substitute maintains the same AEC-Q100 qualification level and operating temperature range. Ensure the replacement supports the required 80 V common-mode voltage input.
