S-8244AAPFN-CEPT2U

Battery Management Overview

The S-8244AAPFN-CEPT2U is a secondary protection IC for lithium-ion battery packs, manufactured by ABLIC. Designed for series-connected cells ranging from one to four, it provides overcharge and overdischarge protection. The device operates within a power supply voltage range of 3.6 V to 24 V and features an output current of 10 uA. It is housed in an MSOP-8 package suitable for surface mount technology. This component serves as a critical safety mechanism in battery management systems.

Battery Management Feature Summary

• Provides secondary protection functions for lithium-ion battery packs consisting of one to four serially connected cells.
• Detects overcharge and overdischarge conditions to disconnect the battery pack via external FET control.
• Operates with a wide power supply voltage range to accommodate various battery configurations.

Battery Management Applications

• Secondary protection circuits for portable electronic devices
• Safety monitoring in lithium-ion battery packs for power tools
• Backup power systems requiring multi-cell battery protection

Battery Management Procurement Notes

Verify the exact suffix CEPT2U against official ABLIC documentation to confirm package type and tape/reel specifications. Confirm availability status as some variants may be discontinued or subject to limited supply. Ensure compatibility with existing PCB footprints and design-in requirements before procurement.

Battery Management Selection Notes

Select this component when secondary protection is required for 1S to 4S lithium-ion battery configurations. Verify that the operating voltage range aligns with the maximum cell count. Ensure the MSOP-8 package fits the board layout constraints. Compare against primary protection ICs if space or cost optimization is needed.

Battery Management Part Context

The S-8244 series is designed specifically for secondary protection in lithium-ion battery applications. It complements primary protection circuits by providing an additional layer of safety against overcharge and overdischarge. The series supports multiple cell counts and offers reliable performance in compact packages.

Battery Management Replacement Considerations

Check ABLIC's official substitution list for direct replacements. Consider equivalent secondary protection ICs from other manufacturers only if pinout and electrical characteristics match exactly. Verify package compatibility and functional equivalence before substituting.
