INA197AIDBVT

Current Regulation/Management Overview

The INA197AIDBVT is a high-side current shunt monitor manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 18 V and supports supply voltages up to 80 V. The device provides an analog output proportional to the differential voltage across a shunt resistor. It features a typical accuracy of 3% and consumes a maximum quiescent current of 900 µA. The component is housed in a SOT-23-5 package and is rated for operation between -40°C and +125°C.

Current Regulation/Management Feature Summary

• High-side current sensing capability with wide common-mode voltage support
• Analog voltage output proportional to shunt voltage drop
• Integrated precision reference for accurate measurement

Current Regulation/Management Applications

• Battery management systems
• Overcurrent protection circuits
• Load switch control

Current Regulation/Management Procurement Notes

Verify the specific suffix 'VT' against the manufacturer datasheet to confirm the tape-and-reel packaging configuration, as distributor listings may vary. Ensure the selected variant matches the required operating temperature range and package dimensions for the target PCB layout. Cross-reference the RoHS compliance status with the latest environmental documents provided by Texas Instruments before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when high-side monitoring is required within an 18 V input limit. The 3% accuracy specification suits general-purpose applications where extreme precision is not critical. Consider the SOT-23-5 footprint constraints and the 900 µA quiescent current draw during power budget calculations. Verify that the analog output interface aligns with the downstream ADC or comparator input requirements.

Current Regulation/Management Part Context

The INA197 belongs to the INA19x family of current shunt monitors from Texas Instruments. This series is designed for cost-effective current sensing in industrial and consumer electronics.
