INA270AQDRQ1

Current Regulation/Management Overview

The INA270AQDRQ1 is an automotive-grade unidirectional current shunt monitor manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 18 V and draws a typical quiescent current of 950 uA. The device supports common-mode input voltages from -16 V to 80 V, enabling high-side or low-side measurement configurations. It is qualified to AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range of -40°C to +125°C. The component is housed in an SOIC-8 surface-mount package.

Current Regulation/Management Feature Summary

• Unidirectional current monitoring with voltage output capability
• Automotive qualification compliant with AEC-Q100 standards
• Wide common-mode voltage range supporting high-side and low-side sensing

Current Regulation/Management Applications

• Automotive battery monitoring systems
• High-side current sensing in power distribution units
• Low-side current measurement in motor control circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix 'AQDRQ1' matches the required automotive grade and package type. Confirm that the unidirectional functionality aligns with the system's current flow requirements. Ensure the SOIC-8 footprint compatibility with the PCB design. Check for any recent product change notices affecting material composition or assembly processes.

Current Regulation/Management Selection Notes

Select this component when unidirectional current monitoring is sufficient for the application. The wide common-mode voltage range allows flexibility in circuit topology. Consider the 950 uA quiescent current if power efficiency is critical. Verify that the SOIC-8 package meets thermal and spatial constraints of the design.

Current Regulation/Management Part Context

This part belongs to the INA270 family of current monitors designed for robust performance in demanding environments. The 'A' indicates accuracy grading, while 'Q1' denotes automotive qualification. The 'DRQ1' suffix specifies the SOIC-8 package and tape-and-reel packaging format suitable for automated assembly processes.

Current Regulation/Management Replacement Considerations

INA270AIDR is a non-automotive grade alternative with similar electrical characteristics but lacks AEC-Q100 certification.
