INA194AIDBVR

Current Regulation/Management Overview

The INA194AIDBVR 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 supports common-mode voltages from -6 V to 80 V. The device provides an output proportional to the voltage drop across a shunt resistor, enabling precise current measurement. Key electrical specifications include a maximum accuracy of 3%, a quiescent current of 900 uA, and a gain of 50 V/V. It functions within a temperature range of -40°C to +125°C and is housed in a SOT-23-5 package.

Current Regulation/Management Feature Summary

• Supports high-side current sensing with a wide common-mode voltage range extending to 80 V
• Provides accurate current monitoring with specified initial accuracy of 3%
• Operates on a single low-voltage power supply ranging from 2.7 V to 18 V

Current Regulation/Management Applications

Current Regulation/Management Procurement Notes

Verify the specific suffix 'AIDBVR' against the manufacturer's latest datasheet to confirm pinout compatibility and electrical tolerances. Ensure the application environment stays within the specified -40°C to +125°C operating temperature range. Confirm that the input common-mode voltage does not exceed the 80 V absolute maximum rating to prevent device damage during procurement validation.

Current Regulation/Management Selection Notes

Select this component when high-side current sensing is required in systems with common-mode voltages up to 80 V. It is suitable for applications needing moderate accuracy (3%) and low quiescent current (900 uA). Consider the SOT-23-5 package constraints for PCB layout. Compare against other INA19x variants if higher precision or different gain factors are necessary for the specific design requirements.

Current Regulation/Management Part Context
