INA300AIDSQT

Current Regulation/Management Overview

The INA300AIDSQT is a current-sense comparator manufactured by Texas Instruments, designed for high-side and low-side sensing applications. It operates within an input voltage range of 2.7V to 5.5V and supports a junction temperature range from -40°C to 125°C. The component is housed in a 10-WSON (2x2) surface-mount package with exposed thermal pads, classified as 10-WFDFN. This device functions as a linear current-sense amplifier intended for integration into power management systems requiring precise monitoring.

Current Regulation/Management Feature Summary

• Supports both high-side and low-side current sensing configurations
• Operates on a single supply voltage ranging from 2.7V to 5.5V
• Features a compact 10-WSON surface-mount package with exposed pad

Current Regulation/Management Applications

• Power management system monitoring
• Current sensing in regulator circuits
• High-side and low-side protection schemes

Current Regulation/Management Procurement Notes

Verify the specific suffix 'QT' against official documentation to confirm qualification status, as standard variants may differ. Confirm package dimensions match the 10-WSON specification during layout. Check for End-of-Life notices, as PCN records indicate potential discontinuation events for this family. Ensure compatibility with the required operating temperature range before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when a dedicated current-sense comparator is required rather than a programmable gain amplifier. The fixed configuration suits applications needing immediate threshold detection without external resistor networks. Consider the 10-WSON footprint constraints and thermal dissipation requirements associated with the exposed pad design for proper PCB integration.

Current Regulation/Management Part Context

This part belongs to the INA300 series of current-sense comparators from Texas Instruments. The series provides solutions for monitoring current flow in power distribution networks. The 'AID' prefix typically denotes specific performance grades or package types within the broader product line, while 'SQT' specifies the tape-and-reel packaging and specific variant characteristics.
