S-8254ABHFT-TB-S

Battery Management Overview

The S-8254ABHFT-TB-S is a battery protection IC designed for 3-series or 4-series lithium-ion and lithium-polymer rechargeable batteries. It integrates high-accuracy voltage detectors and delay circuits to prevent overcharge, overdischarge, and overcurrent conditions. The device operates within a supply voltage range of 2 V to 24 V and supports surface-mount installation in a TSSOP-16 package. It functions reliably across an operating temperature range of -40°C to +85°C.

Battery Management Feature Summary

• Provides comprehensive protection against overcharge, overdischarge, and overcurrent events for multi-cell lithium battery packs.
• Features high-precision voltage detection with specified tolerances for accurate cell monitoring.
• Incorporates internal delay circuits to filter noise and prevent false triggering during transient conditions.

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 cell balancing and fault isolation

Battery Management Procurement Notes

Verify the specific suffix configuration against official ABLIC documentation to ensure correct overcharge threshold selection. Confirm package type and reel specifications match design requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Ensure environmental compliance data aligns with target market regulations prior to final procurement decisions.

Battery Management Selection Notes

Select this component when designing protection systems for 3S or 4S lithium-based battery configurations. Evaluate the required overcharge voltage thresholds based on specific cell chemistry characteristics. Consider the operating temperature range and package constraints for PCB layout. Ensure external MOSFET ratings support the intended current loads and voltage levels.

Battery Management Part Context

This model belongs to the S-8254A series of battery protection integrated circuits manufactured by ABLIC Inc. The series is engineered specifically for safeguarding serial-connected lithium cells. It replaces older discrete protection solutions by integrating detection logic and control functions into a single compact semiconductor device.

Battery Management Replacement Considerations

Direct substitutes include other variants within the S-8254A family, such as S-8254AAHFT-TB-S or S-8254ABMFT-TB-U, provided their electrical thresholds match the application requirements. Verify pin compatibility and functional equivalence before swapping components in existing designs.
