S-8252ACJ-I6T1U

Battery Management Overview

The S-8252ACJ-I6T1U is a battery protection IC designed for two-cell lithium-ion or lithium polymer packs. It operates within a power supply voltage range of 1.5 V to 10 V and features high-accuracy overcharge detection voltages adjustable in 5 mV steps between 3.550 V and 4.600 V per cell. The device utilizes an SNT-6A surface-mount package and supports continuous operation at temperatures from -40°C to +85°C with a maximum power dissipation of 400 mW.

Battery Management Feature Summary

• Provides independent high-accuracy voltage monitoring for each cell in a two-cell series configuration.
• Enables precise overcharge protection through programmable detection thresholds with fine resolution.
• Supports reliable operation across standard industrial temperature ranges with low quiescent current consumption.

Battery Management Applications

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

Battery Management Procurement Notes

Verify the specific overcharge detection voltage setting required for your application, as the ACJ suffix indicates a fixed threshold distinct from other variants in the S-8252 series. Confirm that the SNT-6A package dimensions align with your PCB layout constraints. Ensure compatibility with the target battery chemistry, specifically lithium-ion or lithium-polymer types, before finalizing procurement.

Battery Management Selection Notes

Select this component when designing protection for two-series cells requiring precise overcharge cutoff. Compare the fixed detection voltage against the battery manufacturer's specifications to ensure safety margins are met. Consider the SNT-6A footprint availability and thermal performance under the 400 mW dissipation limit during selection.

Battery Management Part Context

This part belongs to the ABLIC S-8252 series of battery protection ICs. Unlike single-cell models such as the S-8240AAT, this variant is engineered specifically for two-cell configurations. It shares the series' focus on high accuracy and low power consumption while adapting its internal circuitry to monitor multiple cells independently.

Battery Management Replacement Considerations

Direct substitutes include other S-8252 variants like the S-8252ADH or S-8252ABX, provided their specific detection voltage settings match the design requirements. Verify package compatibility and electrical parameters before substitution.
