S-8254ABCFT-TB-G

Battery Management Overview

The S-8254ABCFT-TB-G is a battery protection IC for 3-series or 4-series lithium-ion and lithium polymer rechargeable batteries. It features high-accuracy voltage detectors with overcharge detection at 4.100V ±25mV and release at 4.000V ±50mV. Overdischarge detection is set at 2.00V ±80mV with a release of 2.70V ±100mV. The device includes three-stage overcurrent detection thresholds: 0.20V ±25mV, fixed 0.5V ±100mV, and VC1-1.2V ±300mV. It operates within a power supply voltage range of 2V to 24V and is housed in a TSSOP-16 package.

Battery Management Feature Summary

• Provides comprehensive protection against overcharge, overdischarge, and overcurrent conditions for multi-cell battery packs.
• Integrates a high-accuracy voltage detector system ensuring precise monitoring of individual cell voltages.
• Employs a three-stage overcurrent detection mechanism to handle varying levels of current faults and short circuits.

Battery Management Applications

• Protection circuits for 3-series lithium-ion battery packs
• Safety management for 4-series lithium-polymer battery assemblies
• Portable electronic devices requiring reliable battery cell balancing

Battery Management Procurement Notes

Verify the specific suffix codes on the component marking against the official ABLIC datasheet to confirm the exact voltage thresholds. Ensure the ordering information matches the required overcharge and overdischarge parameters for your specific battery chemistry. Cross-reference the package type and tape/reel specifications with the manufacturer's latest documentation before finalizing procurement orders.

Battery Management Selection Notes

Select this component when designing protection systems for 3S or 4S configurations where precise voltage monitoring is critical. The specific threshold values (4.100V overcharge, 2.00V overdischarge) must align with the nominal voltage and safety limits of the connected cells. Consider the three-stage overcurrent protection capabilities when sizing external MOSFETs and sense resistors for the target application load.

Battery Management Part Context

This part belongs to the S-8254A series, a family of battery protection ICs designed by ABLIC Inc. The series is engineered specifically for safeguarding serial-connected lithium-ion and lithium-polymer batteries. It integrates essential detection functions into a single compact package, reducing the need for multiple discrete components in battery management designs.

Battery Management Replacement Considerations

Direct substitutes include other variants within the S-8254A series such as S-8254AAFFT-TB-G or S-8254ABMFT-TB-U, provided their voltage thresholds match the design requirements. Verify that any replacement maintains the same TSSOP-16 footprint and electrical characteristics for seamless integration.
