S-8254ABMFT-TB-U

Battery Management Overview

The S-8254ABMFT-TB-U is a battery protection IC from ABLIC designed for 3-series or 4-series lithium-ion and lithium-polymer rechargeable batteries. It integrates high-accuracy voltage detectors and delay circuits to protect the battery pack. The device operates within a power supply voltage range of 2 V to 24 V and is housed in a TSSOP-16 package suitable for surface mount technology.

Battery Management Feature Summary

• Provides overcharge, overdischarge, and overcurrent protection for multi-cell lithium battery packs
• Integrates high-accuracy voltage detection with built-in delay circuits to prevent false triggering
• Supports switching control via SEL pin for flexible configuration of 3-series or 4-series cells

Battery Management Applications

• Protection circuits for 3-series lithium-ion battery packs
• Protection circuits for 4-series lithium-polymer battery packs
• Portable electronic devices requiring multi-cell battery management

Battery Management Procurement Notes

Verify the specific overcharge voltage threshold associated with the 'B' suffix against official datasheets, as this parameter defines the protection level. Confirm that the TSSOP-16 package and reel packaging align with your assembly requirements. Ensure compatibility with your target cell chemistry before integration.

Battery Management Selection Notes

Select this component when designing protection for 3 or 4 series connected lithium cells. The 'B' variant indicates a specific overcharge voltage threshold; verify this matches your cell's maximum charging limit. Consider the operating voltage range up to 24 V to ensure it covers the fully charged state of your battery configuration.

Battery Management Part Context

This part belongs to the S-8254 series, which are dedicated protection ICs for serial-connected lithium batteries. The series is characterized by high accuracy and integrated delay functions to enhance safety. The S-8254ABMFT-TB-U specifically utilizes the TSSOP-16 package for compact PCB layouts.

Battery Management Replacement Considerations

Direct substitutes must match the S-8254 series functionality, TSSOP-16 package, and the specific 'B' voltage threshold. Verify electrical parameters and pinout compatibility before substitution.
