INA202AID

Current Regulation/Management Overview

The INA202AID is a high-side current shunt monitor manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates with a supply voltage range of 2.7 V to 18 V and supports input common-mode voltages from -16 V to 80 V. The device features a typical quiescent current of 1.85 mA and maintains an accuracy of ±3.5%. It functions within an extended temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Enables precise current monitoring on the high side of a circuit using a single external shunt resistor.

Current Regulation/Management Applications

• Battery management systems
• Power distribution units
• Overcurrent protection circuits

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and moisture sensitivity level handling requirements during storage and assembly. Cross-reference datasheet revisions for any parameter updates prior to final design implementation.

Current Regulation/Management Selection Notes

Select this component for applications requiring high-side current sensing with wide common-mode voltage tolerance. Ensure the external shunt resistor value aligns with the required output voltage swing given the fixed gain characteristics. Verify thermal performance within the specified operating temperature range.

Current Regulation/Management Part Context

This part belongs to the INA202 series of current monitors. It is designed for simple, low-cost current sensing solutions where high precision is not the primary requirement compared to other family members like the INA200 or INA210.
