INA200AIDGKRG4

Overview

The INA200AIDGKRG4 is a high-side current shunt monitor manufactured by Texas Instruments. It integrates an operational amplifier, an open-drain comparator, and a precision voltage reference within a single VSSOP-8 package. The device supports input voltages ranging from 2.7 V to 18 V, enabling accurate current sensing in systems with varying supply levels. It features a fixed gain of 20 V/V for the amplifier section and includes a built-in 2.5-V reference output. The component operates across an extended temperature range of -40°C to +125°C, ensuring reliability in industrial environments.

Feature Summary

• Integrates a precision amplifier, open-drain comparator, and voltage reference in a compact surface-mount package
• Supports high-side current measurement with input voltage capability up to 18 V
• Provides a stable internal reference output for external circuit requirements

Applications

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

Procurement Notes

Verify the specific suffix RG4 indicates reel packaging when sourcing. Confirm the A-grade designation matches required offset voltage specifications. Ensure the VSSOP-8 footprint aligns with existing PCB layouts. Check humidity sensitivity classification for proper storage handling. Validate that the open-drain comparator output logic suits the downstream interface.

Selection Notes

Select this component when high-side sensing is required within an 18 V common-mode range. The integrated comparator simplifies overcurrent detection without additional discrete components. Consider the fixed 20 V/V gain for direct signal conditioning needs. Evaluate the thermal performance at maximum operating temperatures. Compare power consumption against system budget constraints.

Part Context

This part belongs to the INA200 family of current shunt monitors designed for robust industrial applications. The device combines multiple functions typically found in separate ICs to reduce board space. It serves as a solution for monitoring current in systems where the shunt resistor is placed on the high side of the load.

Replacement Considerations

INA200AIDGKR is a compatible alternative with identical electrical characteristics but different packaging format.
