S-8244AAWFN-CEWT2G

Battery Management Overview

The S-8244AAWFN-CEWT2G 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 power 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.

Battery Management Feature Summary

• Provides secondary protection for 1 to 4 serial cell lithium-ion battery packs
• Integrates internal high-precision voltage detector circuits for accurate monitoring
• Supports overcharge, overdischarge, and overcurrent detection functions

Battery Management Applications

• Lithium-ion battery pack secondary protection
• Portable electronic devices requiring multi-cell battery management
• Power tools with serial cell battery configurations

Battery Management Procurement Notes

Verify the exact suffix CEWT2G against official ABLIC documentation to confirm package type and tape/reel specifications. Confirm end-of-life status as some related S-8244 variants are discontinued. Ensure compatibility with existing PCB footprints for MSOP-8 packages before procurement.

Battery Management Selection Notes

Select this component when secondary protection is required for 1S to 4S lithium-ion systems. Verify that the overcharge detection voltage range of 3.700 V to 4.550 V meets system requirements. Check that the MSOP-8 package fits the design constraints and that the operating voltage range covers the maximum pack voltage.

Battery Management Part Context

This part belongs to the S-8244 series from ABLIC Inc., designed specifically for battery protection applications. The series offers various package options including MSOP-8 and TMSOP-8. It serves as a secondary protection layer complementing primary protection circuits in multi-cell battery assemblies.

Battery Management Replacement Considerations

Check ABLIC datasheets for direct pin-compatible alternatives within the S-8244 family. Verify if other suffixes like CEUT2S or CEDT2U offer identical electrical characteristics. Ensure any substitute maintains the same 1-4 cell support and MSOP-8 footprint.
