INA282AQDGKRQ1

Current Regulation/Management Overview

The INA282AQDGKRQ1 is an automotive-grade, bidirectional current shunt monitor from Texas Instruments. It operates with a supply voltage range of 2.7 V to 18 V and draws a typical quiescent current of 600 uA. The device supports high-side or low-side sensing with a common-mode voltage range of -14 V to +80 V. It features a gain of 20 V/V and maintains an accuracy of ±1.4% over the operating temperature range of -40°C to +125°C. The component is housed in an 8-pin VSSOP package and meets AEC-Q100 qualification standards.

Current Regulation/Management Feature Summary

• Bidirectional current monitoring capability for both sourcing and sinking applications
• Zero-drift architecture ensuring high precision across wide temperature ranges
• Wide common-mode voltage support enabling flexible high-side and low-side placement

Current Regulation/Management Applications

• Automotive battery management systems
• Electric vehicle powertrain control units
• Industrial motor drive current sensing

Current Regulation/Management Procurement Notes

Verify the specific suffix 'AQDGKRQ1' matches the required automotive grade (A), accuracy class (A), package type (DGK), reel quantity (R), and automotive qualification (Q1). Confirm that the datasheet revision aligns with your design requirements. Ensure compatibility with your PCB footprint for the 8-VSSOP package. Check for any recent product change notices regarding assembly sites or materials.

Current Regulation/Management Selection Notes

Select this component when bidirectional measurement is required within an automotive environment. The ±1.4% accuracy suits applications demanding precise current tracking without complex calibration. The wide common-mode range allows operation in noisy power environments typical of electric vehicles. Consider the 600 uA quiescent current for battery-powered subsystems where efficiency is critical.

Current Regulation/Management Part Context

This part belongs to the INA28x-Q1 family of high-accuracy, bidirectional current shunt monitors. It shares architectural similarities with other zero-drift amplifiers but is optimized for shunt-based current sensing. The Q1 designation indicates compliance with automotive reliability standards, distinguishing it from commercial variants like the INA282AIDGKR.

Current Regulation/Management Replacement Considerations

INA282AQDRQ1 is a pin-compatible alternative in an SOIC-8 package.
