INA202AIDGKR

Current Regulation/Management Overview

The INA202AIDGKR is a high-side current shunt monitor manufactured by Texas Instruments, designed for precise current sensing in power management applications. It operates with a supply voltage range of 2.7 V to 18 V and supports common-mode input voltages from -16 V 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-VSSOP package and functions within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Supports high-side current measurement with wide common-mode voltage tolerance
• Provides accurate current monitoring with specified gain error performance
• Operates on low single-supply voltage with minimal quiescent current consumption

Current Regulation/Management Applications

• Battery protection circuits
• Overcurrent protection systems
• Load switch control
• Power delivery monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DGKR' corresponds to the VSSOP-8 tape and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact grade and package variant required for your design specifications.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required with a common-mode voltage exceeding the supply rail. The ±3.5% accuracy suits general-purpose monitoring where extreme precision is not critical. Consider the 8-VSSOP package for space-constrained surface-mount designs requiring thermal performance up to 125°C.

Current Regulation/Management Part Context

This device belongs to the INA200 series of current shunt monitors from Texas Instruments. It shares functional similarities with the INA200 and INA201 but offers specific accuracy and package options tailored for cost-sensitive industrial and consumer electronics applications requiring reliable current feedback.

Current Regulation/Management Replacement Considerations

The INA202AIDR is listed as a manufacturer-recommended alternative with identical electrical characteristics but in a different tape-and-reel packaging format. Verify pinout compatibility and package dimensions before substitution.
