INA200AIDGKTG4

Current Regulation/Management Overview

The INA200AIDGKTG4 is a high-side current shunt monitor manufactured by Texas Instruments. It operates with a supply voltage range of 2.7 V to 18 V and draws a typical operating supply current of 1.85 mA. The device provides an output voltage proportional to the differential voltage across a shunt resistor, enabling precise current measurement. It features an accuracy of ±3.5% over temperature and supports common-mode voltages from -0.1 V to 80 V. The component is housed in an 8-pin VSSOP package and functions within a junction temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Provides a linear output voltage directly proportional to the differential input voltage across the sensing element.
• Supports high-side current monitoring with a wide common-mode voltage range extending up to 80 V.
• Maintains specified accuracy performance across the full industrial operating temperature range.

Current Regulation/Management Applications

• Battery management systems requiring precise current monitoring
• Overcurrent protection circuits in power distribution networks
• Industrial process control equipment for load regulation

Current Regulation/Management Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the package designation matches the required PCB footprint dimensions. Check the active lifecycle status as availability may be limited due to end-of-life notifications. Ensure the operating voltage requirements align with the system's common-mode constraints.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required within an 18 V supply limit. Consider the ±3.5% accuracy specification against system tolerance requirements. Evaluate the 1.85 mA supply current impact on total power budget. Verify that the 80 V common-mode range covers the maximum expected bus voltage during fault conditions.

Current Regulation/Management Part Context

This part belongs to the INA200 series of current shunt monitors designed for low-cost, high-accuracy applications. It serves as a fundamental building block for power management architectures where direct current measurement is necessary without galvanic isolation. The VSSOP-8 package allows for compact board layouts in space-constrained designs.

Current Regulation/Management Replacement Considerations

INA200AIDGKR is listed as a manufacturer-recommended alternative with identical functional specifications but potentially different packaging options.
