INA169NA/3KG4

Current Regulation/Management Overview

The INA169NA/3KG4 is a high-side current shunt monitor manufactured by Texas Instruments. It operates with an input voltage range of 2.7 V to 60 V and features a maximum supply current of 125 uA. The device provides 0.5% accuracy and functions within a temperature range of -40°C to +125°C. It is housed in a SOT-23-5 surface-mount package.

Current Regulation/Management Feature Summary

• High-side measurement capability for monitoring current through a shunt resistor
• Current output interface for direct connection to analog-to-digital converters
• Low power consumption suitable for battery-operated systems

Current Regulation/Management Applications

• Programmable Logic Controller (PLC) current sensing
• Power management system monitoring
• Industrial process control equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per the manufacturer's datasheet. Confirm the '/3K' designation corresponds to the standard cut-tape or reel packaging quantity of 3000 units. Ensure the component matches the exact pinout and thermal characteristics required for the target PCB layout before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when high-side current monitoring is required within a 60 V common-mode range. It is appropriate for applications needing low quiescent current and precise current feedback without the complexity of differential voltage outputs. Consider the SOT-23-5 package constraints for thermal dissipation and board space availability during integration.

Current Regulation/Management Part Context

This part belongs to the INA169 family of high-side current shunt monitors from Texas Instruments. It shares functional similarities with other members like the INA169NA/250 but differs in packaging quantity. The series is designed for industrial and commercial applications requiring reliable current sensing in power management circuits.
