S-8244AAVFM-CEVT2U

Battery Management Overview

The S-8244AAVFM-CEVT2U is a secondary protection IC for lithium-ion battery packs containing one to four series-connected cells. It monitors cell voltage and current to prevent overcharge, overdischarge, and overcurrent conditions. The device operates within a supply voltage range of 3.6 V to 24 V and features a low output current of 10 uA. It is housed in an MSOP-8 package and supports surface mount installation.

Battery Management Feature Summary

• Provides secondary protection functions for multi-cell lithium-ion battery packs
• Integrates monitoring for overcharge, overdischarge, and overcurrent states
• Designed for compact surface-mount applications with low standby consumption

Battery Management Applications

• Secondary protection circuits for portable electronic devices
• Battery management systems for power tools
• Protection modules for medical equipment batteries
• Uninterruptible power supply (UPS) battery packs

Battery Management Procurement Notes

Verify the exact suffix CEVT2U 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. Request latest datasheet for electrical characteristics and ensure compatibility with existing PCB footprints before procurement.

Battery Management Selection Notes

Select this component when secondary protection is required for 1S to 4S lithium-ion configurations. Ensure the operating voltage range covers the maximum pack voltage. Verify that the MSOP-8 package fits the design constraints. Compare against primary protection ICs if space or cost is critical, noting this device handles secondary safety cutoffs.

Battery Management Part Context

This part belongs to the S-8244 series of battery protection ICs from ABLIC. The series is designed for lithium-ion and lithium-polymer batteries. Variants differ by package style and termination options. This specific model targets high-reliability applications requiring precise voltage monitoring and low power consumption in a small form factor.

Battery Management Replacement Considerations

Check for direct pin-compatible substitutes within the S-8244 family such as S-8244AAUFN or S-8244AAWFN. Verify functional equivalence regarding detection voltages and delays. Consider obsolescence status of original parts when selecting alternatives.
