S-8244ABBPH-CFBTFU

Battery Management Overview

The S-8244ABBPH-CFBTFU is a secondary protection IC for lithium-ion battery packs consisting of one to four series-connected cells. It operates within a supply voltage range of 3.6 V to 24 V and features an internal high-precision voltage detector with overcharge detection accuracy of ±25 mV at +25°C. The device supports detection voltages from 3.700 V to 4.550 V, consumes 3 µA of operating current, and dissipates up to 450 mW. It is housed in an SNT-8A surface-mount package and functions reliably between -40°C and +85°C.

Battery Management Feature Summary

• Provides secondary protection for multi-cell lithium-ion battery packs
• Integrates high-precision voltage detection circuits for accurate monitoring
• Designed for low-power operation suitable for portable applications

Battery Management Applications

• Secondary protection for 1S to 4S lithium-ion battery packs
• Portable electronic devices requiring precise cell monitoring
• Battery management systems needing redundant safety layers

Battery Management Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and detection voltage settings. Ensure the SNT-8A package footprint matches your PCB design constraints. Confirm that the component meets RoHS requirements if mandated by your assembly standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Battery Management Selection Notes

Select this component when a dedicated secondary protection layer is required alongside primary control circuitry. The SNT-8A package offers a compact solution for space-constrained designs. Consider the ±25 mV accuracy requirement for applications demanding tight voltage tolerance. Evaluate the 3 µA quiescent current impact on overall system standby power consumption.

Battery Management Part Context

This part belongs to the S-8244 series of battery protection ICs manufactured by ABLIC Inc. The series is designed specifically for lithium-ion and lithium-polymer batteries. The S-8244ABBPH-CFBTFU variant utilizes the SNT-8A package, distinguishing it from MSOP or other form factors within the same functional family.

Battery Management Replacement Considerations

Direct replacements must match the S-8244 series functionality and SNT-8A package. Verify that any substitute maintains the same overcharge detection voltage range and accuracy specifications. Check for identical pin configurations to ensure board-level compatibility without redesign.
