S-8254AABFT-TB-U

Battery Management Overview

The S-8254AABFT-TB-U is a battery protection IC designed for lithium-ion and lithium-polymer batteries in 3-cell or 4-cell series configurations. It operates within a power supply voltage range of 2 V to 24 V and utilizes a TSSOP-16 surface-mount package. The device provides comprehensive protection against overcharge, over-discharge, and overcurrent conditions specific to multi-cell battery packs.

Battery Management Feature Summary

• Provides integrated protection functions for 3-series or 4-series lithium-ion and lithium-polymer battery packs
• Features high-precision voltage detection circuits for monitoring individual cell states
• Incorporates a three-stage overcurrent protection mechanism to handle varying fault intensities

Battery Management Applications

• Protection circuits for portable electronic devices using multi-cell battery packs
• Safety management systems for electric tools with 3S or 4S battery configurations
• Backup power supplies requiring reliable lithium battery cell balancing and protection

Battery Management Procurement Notes

Verify the exact overcharge detection voltage threshold associated with the 'AA' suffix variant before procurement. Confirm that the TSSOP-16 package dimensions align with the target PCB footprint. Ensure the operating voltage range covers the maximum pack voltage of the intended application. Cross-reference the RoHS compliance status with current regulatory requirements for the destination market.

Battery Management Selection Notes

Select this component when designing protection circuits for 3S or 4S lithium-based battery architectures. The fixed detection thresholds defined by the 'AA' suffix suit applications requiring standard charge termination voltages. Consider the TSSOP-16 package for space-constrained designs requiring surface-mount assembly. Evaluate the three-stage overcurrent response to match the specific load characteristics and fault tolerance needs of the system.
