S-8244AAHFN-CEHT2U

Battery Management Overview

The S-8244AAHFN-CEHT2U 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 suitable for surface mount technology.

Battery Management Feature Summary

• Provides secondary protection functions for multi-cell lithium-ion battery packs
• Monitors individual cell voltages to detect overcharge and overdischarge states
• Detects overcurrent conditions during charge and discharge cycles

Battery Management Applications

• Secondary protection circuits for portable electronic devices
• Battery management systems for power tools
• Protection modules for medical equipment batteries

Battery Management Procurement Notes

Verify the specific suffix CEHT2U against official ABLIC documentation to confirm package type and tape/reel specifications. Confirm availability status as distribution data may indicate end-of-life or discontinuation for certain variants. Ensure compatibility with existing PCB footprints for MSOP-8 packages before procurement.

Battery Management Selection Notes

Select this component when designing secondary protection layers for 1S to 4S lithium-ion configurations. Verify that the operating voltage range covers the maximum pack voltage. Ensure the package style matches the assembly requirements. Cross-reference with primary protection ICs to ensure coordinated timing and voltage thresholds.

Battery Management Part Context

This part belongs to the S-8244 series of battery protection ICs from ABLIC. The series is designed specifically for secondary protection applications in multi-cell battery packs. It complements primary protection solutions by providing independent monitoring capabilities.

Battery Management Replacement Considerations

Check for direct substitutes within the S-8244 family with different suffixes. Verify pin compatibility and electrical parameters before substituting. Consult official datasheets for any functional differences between variants.
