INA202AIDGKT

Current Regulation/Management Overview

The INA202AIDGKT is a high-side current shunt monitor manufactured by Texas Instruments, designed for precise measurement of current flowing through a shunt resistor. It operates within a supply voltage range of 2.7 V to 18 V and supports common-mode voltages up to 80 V. The device features an accuracy of ±3.5% and draws a typical operating supply current of 1.85 mA. It is housed in an 8-pin VSSOP package and functions reliably across an extended temperature range from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Supports high-side current sensing with common-mode voltage tolerance up to 80 V
• Provides accurate current monitoring with specified gain error of ±3.5%
• Operates on low supply voltage ranging from 2.7 V to 18 V
• Designed for surface-mount installation in compact electronic systems

Current Regulation/Management Applications

• Battery management systems requiring high-side current monitoring
• Overcurrent protection circuits in industrial equipment
• Current sensing in power distribution units
• Load detection in automotive electronics

Current Regulation/Management Procurement Notes

Verify the exact suffix GKT confirms the VSSOP-8 tape and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for your assembly process. Check for any recent product change notices regarding manufacturing sites or material composition updates before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required with a common-mode voltage exceeding the supply rail. Ensure the shunt resistor value allows for sufficient output voltage swing within the 2.7 V to 18 V supply range. Consider the ±3.5% accuracy specification against system tolerance requirements. Verify that the VSSOP-8 package fits the available PCB footprint constraints.

Current Regulation/Management Part Context

The INA202 belongs to the INA200 series of current shunt monitors from Texas Instruments. This family provides single-channel amplification of differential voltages across shunt resistors. The INA202 variant offers specific gain characteristics suitable for general-purpose current monitoring applications where moderate accuracy and wide common-mode voltage ranges are necessary.

Current Regulation/Management Replacement Considerations

INA202AIDGKR is a documented manufacturer-recommended replacement offering identical electrical specifications in a compatible VSSOP-8 package format.
