S-8252AAM-I6T1U

Battery Management Overview

The S-8252AAM-I6T1U is a battery protection IC designed for two-cell lithium-ion or lithium polymer packs. It operates within a supply voltage range of 1.5 V to 10 V and consumes a typical quiescent current of 4 µA. The device features high-accuracy overcharge detection voltages adjustable in 5 mV steps from 3.550 V to 4.600 V per cell. It is housed in an SNT-6A surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Battery Management Feature Summary

• Provides independent high-accuracy voltage detection for each cell in a dual-cell configuration
• Enables precise overcharge protection with finely adjustable detection thresholds
• Maintains ultra-low power consumption suitable for portable electronic devices

Battery Management Applications

• Protection circuits for two-cell lithium-ion battery packs
• Safety management for lithium polymer battery assemblies
• Portable consumer electronics requiring dual-cell power sources

Battery Management Procurement Notes

Verify the specific overcharge detection voltage setting required for your application, as the AAM suffix indicates a fixed factory-set value distinct from other variants in the series. Confirm that the SNT-6A package dimensions align with your PCB layout constraints. Ensure the operating voltage range covers your system's maximum pack voltage under all conditions.

Battery Management Selection Notes

Select this component when designing protection for two-series cells requiring precise overcharge monitoring. Compare the fixed detection voltage against your battery chemistry specifications to ensure compliance. Consider the low standby current if battery longevity in storage mode is a critical design parameter.

Battery Management Part Context

This part belongs to the S-8252 series of battery protection ICs from ABLIC Inc. The series offers various detection voltage options and package configurations. The AAM variant specifically targets dual-cell applications with a predefined overcharge threshold, differentiating it from single-cell models like the S-8240 series.

Battery Management Replacement Considerations

Direct replacements must support two-cell protection and match the SNT-6A footprint. Verify that alternative parts offer compatible detection voltages and similar quiescent current characteristics to maintain system efficiency.
