S-8244AAFFN-CEFT2G

Battery Management Overview

The S-8244AAFFN-CEFT2G is a secondary protection IC for lithium-ion battery packs containing one to four series-connected cells. It provides overcharge, overdischarge, and overcurrent protection functions. The device operates within a supply voltage range of 3.6 V to 24 V and features an output current capability of 10 uA. It is housed in an MSOP-8 package designed for surface mount technology.

Battery Management Feature Summary

• Provides secondary protection for 1S to 4S lithium-ion battery configurations
• Integrates overcharge, overdischarge, and overcurrent detection circuits
• Designed for low standby current consumption in portable applications

Battery Management Applications

• Lithium-ion battery packs for portable electronics
• Secondary protection circuits in power tool batteries
• Backup power systems requiring multi-cell series management

Battery Management Procurement Notes

Verify the specific suffix CEFT2G against official ABLIC documentation to confirm package type and tape/reel specifications. Confirm end-of-life status as similar S-8244 variants are marked obsolete. Ensure compatibility with existing PCB footprints for MSOP-8 packages before procurement.

Battery Management Selection Notes

Select this component when designing secondary protection for 1S to 4S Li-ion packs requiring high reliability. Verify that the operating voltage range covers the maximum pack voltage. Ensure the package size fits the available board space and manufacturing capabilities.

Battery Management Part Context

This part belongs to the S-8244 series of battery protection ICs from ABLIC. These devices are engineered specifically for secondary protection roles, complementing primary protection circuits. The series supports various cell counts and packaging options to suit different form factors.

Battery Management Replacement Considerations

Check for direct pin-compatible substitutes within the S-8244 family. Verify if older revisions like S-8244AAUFN or S-8244AAWFN offer equivalent electrical characteristics. Confirm availability of active stock for alternative suffixes.
