AAT3681AIJS-4.2-1-T1

Overview

The AAT3681AIJS-4.2-1-T1 is a linear battery charger IC designed for single-cell lithium-ion and lithium-polymer batteries, manufactured by Skyworks Solutions Inc. It operates within a supply voltage range of 4 V to 7.5 V and delivers a regulated output voltage of 4.2 V. The device features a low quiescent current of 500 uA and supports surface-mount installation in an SC70JW-8 package. It functions reliably across an operating temperature range from -40 C to +85 C, with a maximum power dissipation of 687 mW.

Feature Summary

Linear charging architecture optimized for portable applications
Integrated over-voltage protection mechanisms
Supports standard lithium-ion and lithium-polymer chemistries

Applications

USB port powered battery charging systems
AC adapter based battery management circuits
Portable electronic device power regulation

Procurement Notes

This component is officially discontinued by the manufacturer. Availability is restricted, and it may not be sold in all regions. Verify end-of-life status and source availability through authorized distributors before design finalization. Ensure compliance with RoHS requirements as specified in official documentation.

Selection Notes

Select this part for legacy designs requiring a compact linear charger solution. Confirm that the 4.2 V output threshold matches the target battery specifications. Evaluate thermal performance given the 687 mW power dissipation limit in the SC70JW-8 package. Consider alternative active components if higher efficiency or different input voltage ranges are required.

Part Context

Part of the Skyworks AAT3681 series, this IC belongs to the PMIC category specifically for charge management. It shares the SC70JW-8 footprint with other variants but differs in output voltage settings. The suffix indicates specific pinout and electrical characteristics defined by the manufacturer's datasheet.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Due to the discontinued status, direct replacements must be identified through manufacturer cross-reference tools or functional equivalents with compatible pinouts and electrical parameters.
