INA168NA/3K

Current Regulation/Management Overview

The INA168NA/3K is a high-side current shunt monitor manufactured by Texas Instruments, designed for precise current sensing in power management systems. It operates with an input voltage range of 2.7 V to 60 V and maintains a low quiescent current of 60 uA. The device offers an accuracy of 0.5% and functions within a temperature range of -40°C to +125°C. Packaged in a compact SOT-23-5 surface-mount format, it supports reel, cut tape, and MouseReel packaging options.

Current Regulation/Management Feature Summary

• High-side current monitoring capability with independent input common-mode and supply voltages
• Low static current consumption enabling efficient power management applications
• Wide operating voltage range supporting diverse system power architectures

Current Regulation/Management Applications

• Battery protection circuits
• Power distribution units
• Overcurrent protection systems

Current Regulation/Management Procurement Notes

Verify the specific suffix '3K' corresponds to the required 3000-unit reel quantity during procurement. Confirm RoHS compliance status through official datasheets. Ensure ESD handling protocols are followed due to humidity sensitivity classification. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing orders.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required within a 60 V limit. The 0.5% accuracy suits general-purpose monitoring where extreme precision is not critical. Consider the SOT-23-5 package for space-constrained designs. Evaluate the 60 uA quiescent current against system power budgets. Compare against similar family members like INA169 if higher current consumption is acceptable for other features.

Current Regulation/Management Part Context

This device belongs to the INA168 series of current monitors from Texas Instruments. It shares core specifications with variants like INA168NA/250, differing primarily in packaging quantities. The series is categorized under PMIC Current & Power Monitors. It complements other TI analog signal chain products for comprehensive power management solutions.

Current Regulation/Management Replacement Considerations

INA168NA/250 serves as a direct functional substitute with identical electrical characteristics but different factory packaging quantity (250 units). Verify pinout compatibility and thermal performance similarities before substitution.
