S-8252ACF-M6T1U

Battery Management Overview

The S-8252ACF-M6T1U is a battery protection IC designed for two-series-cell lithium-ion or lithium-polymer packs. It integrates overcharge, overdischarge, and overcurrent protection functions. Key voltage thresholds include an overcharge detection voltage of 4.225 V and an overdischarge detection voltage of 2.900 V. The device features a delay time of 0.190 s for overcharge and 0.500 s for overdischarge to prevent false triggering. It operates within a supply voltage range compatible with series-connected cells and utilizes a compact SOT-23-6 package.

Battery Management Feature Summary

• Integrates protection against overcharge, overdischarge, and excessive current flow in dual-cell battery configurations.
• Provides precise voltage monitoring with defined detection thresholds and built-in delay timers to ensure stable operation.
• Designed for direct connection to lithium-ion and lithium-polymer cell stacks without requiring external sensing components.

Battery Management Applications

• Protection circuits for portable electronic devices using two-series lithium-ion batteries
• Battery management systems in consumer electronics requiring compact form factors
• Power protection modules for medical equipment utilizing dual-cell lithium polymer packs

Battery Management Procurement Notes

Verify the specific suffix M6T1U corresponds to the required tape-and-reel packaging quantity and marking configuration. Confirm that the 4.225 V overcharge threshold aligns with the target battery chemistry specifications. Ensure the SOT-23-6 footprint matches the design layout. Cross-reference the revision number Rev.3.9_00 for accurate electrical characteristics during final validation.

Battery Management Selection Notes

Select this component when designing protection for exactly two series-connected lithium cells. The fixed 4.225 V threshold suits standard lithium-ion chemistries. Consider the SOT-23-6 package size constraints. Verify that the integrated delay times meet the system's transient immunity requirements. This part is unsuitable for single-cell or three-cell configurations due to its specific voltage architecture.

Battery Management Part Context

The S-8252 series comprises battery protection ICs from ABLIC Inc., tailored for multi-cell lithium battery packs. The S-8252ACF variant specifically addresses two-series applications. These devices consolidate multiple protection functions into a single chip to reduce board space and component count. The series is widely used in industries demanding reliable battery safety management.

Battery Management Replacement Considerations

Direct substitutes must support two-series lithium cell protection with similar voltage thresholds. Verify pin compatibility for SOT-23-6 packages. Check if alternative parts offer identical overcharge/overdischarge detection voltages and delay times. Ensure the replacement maintains the same active-low output logic if interfacing with existing control circuitry.
