INA193AIDBVRG4

Current Regulation/Management Overview

The INA193AIDBVRG4 is a high-side current shunt monitor manufactured by Texas Instruments. It features a wide common-mode voltage range of -16 V to 80 V, allowing accurate measurement across various power systems. The device operates on a single supply voltage from 2.7 V to 18 V with a typical quiescent current of 900 µA. It provides a fixed gain of 20 V/V and an analog output proportional to the sensed current. Key electrical specifications include a maximum input offset voltage of 2 mV, a bandwidth of 500 kHz, and an accuracy of ±3%. The component is housed in a compact SOT-23-5 package.

Current Regulation/Management Feature Summary

• Supports high-side current sensing within a -16 V to 80 V common-mode range
• Provides a fixed voltage gain of 20 V/V for direct interface with ADCs or microcontrollers
• Operates efficiently with low quiescent current consumption under single-supply conditions

Current Regulation/Management Applications

• Battery management systems in electric vehicles and portable electronics
• Overcurrent protection circuits in industrial motor drives
• Power monitoring in data center server power distribution units

Current Regulation/Management Procurement Notes

Verify that the ordering suffix 'G4' confirms compliance with RoHS standards and specifies the standard tape-and-reel packaging format. Ensure the procurement channel sources genuine Texas Instruments components to guarantee the specified electrical parameters and reliability ratings are met for the final application design.

Current Regulation/Management Selection Notes

Select this component when a wide common-mode voltage range up to 80 V is required for high-side sensing applications. It is suitable for designs needing a fixed 20 V/V gain without external resistor calibration. Consider the SOT-23-5 package size constraints and the 500 kHz bandwidth limitations when evaluating signal integrity requirements.

Current Regulation/Management Part Context

This part belongs to the INA193 family of current shunt monitors designed for robust performance in harsh environments. It complements other Texas Instruments precision amplifiers by offering a specialized solution for high-voltage current monitoring. The device integrates essential functions into a small footprint, reducing board space compared to discrete solutions.

Current Regulation/Management Replacement Considerations

The automotive-grade variant INA193AQDBVRQ1 serves as a qualified substitute for AEC-Q100 certified applications. For non-automotive uses, the standard INA193AIDBVR offers identical electrical characteristics. Verify pinout compatibility and thermal performance before substituting.
