INA201AIDGKR

Current Regulation/Management Overview

The INA201AIDGKR is a high-side current shunt monitor manufactured by Texas Instruments, designed for precise current measurement in power management systems. It operates within a supply voltage range of 2.7 V to 18 V and supports bidirectional sensing capabilities. The device features an accuracy of 3.5% and consumes a typical operating supply current of 1.85 mA. It is housed in an 8-pin VSSOP package suitable for surface-mount applications. The component functions reliably across an extended temperature range from -40°C to +125°C, ensuring stability in demanding industrial environments.

Current Regulation/Management Feature Summary

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

Current Regulation/Management Applications

• Battery-powered equipment current monitoring
• Industrial process control system regulation
• Power distribution unit protection circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DGKR' indicates the tape-and-reel packaging format when ordering. Confirm that the A-grade accuracy specification meets your circuit requirements. Ensure compatibility with your PCB footprint for the VSSOP-8 package. Check for moisture sensitivity level compliance during storage and handling procedures prior to assembly.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required without ground reference shifts. Consider the 3.5% accuracy limit for precision applications where tighter tolerances are necessary. Evaluate the 1.85 mA supply current against battery life constraints in portable devices. Compare input common-mode voltage limits against your system's maximum bus voltage to ensure safe operation margins.

Current Regulation/Management Part Context

This part belongs to the INA201 series of current shunt monitors from Texas Instruments. It shares the VSSOP-8 package form factor with other devices in the family but differs in internal gain and accuracy specifications. The series is designed for general-purpose current sensing in power management and protection applications.

Current Regulation/Management Replacement Considerations

The INA201AIDGKT is a compatible alternative offering identical electrical characteristics in a cut-tape package format. Verify pinout compatibility before substitution. No direct cross-brand equivalents are confirmed in the provided documentation.
