S-8242BAH-T8T1G

Battery Management Overview

The S-8242BAH-T8T1G is a battery protection IC designed for two-cell serial lithium-ion or lithium polymer battery packs. It provides comprehensive protection against overcharge, overdischarge, and overcurrent conditions. The device operates within a supply voltage range of 1.5 V to 28 V and supports a maximum output voltage of 4.35 V per cell. It is housed in an 8-pin TSSOP package suitable for surface mount technology. The component functions reliably across an operating temperature range from -40°C to +85°C.

Battery Management Feature Summary

• Integrated protection circuitry for dual-series cell configurations
• Supports both lithium-ion and lithium-polymer battery chemistries
• Includes overcharge, overdischarge, and overcurrent detection mechanisms

Battery Management Applications

• Portable electronic devices requiring dual-cell power sources
• Lithium-ion battery pack management systems
• Consumer electronics with integrated battery protection needs

Battery Management Procurement Notes

Verify the specific suffix 'AH' against the manufacturer's current datasheet to confirm pinout and functional specifications, as suffixes often denote critical variations. Confirm RoHS compliance status directly with ABLIC Inc. or authorized distributors. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Request the latest revision document to validate any recent design changes or updates.

Battery Management Selection Notes

Select this component when designing circuits for two-cell serial lithium-based battery packs requiring integrated protection. Ensure the application voltage does not exceed the 28 V absolute maximum rating. Verify that the required operating temperature range falls within the specified -40°C to +85°C limits. Consider the TSSOP-8 package constraints for PCB layout and thermal management during the design phase.

Battery Management Part Context

This part belongs to the S-8242 series of battery protection ICs manufactured by ABLIC Inc. The series is engineered for portable applications where space and efficiency are critical. The S-8242BAH variant specifically targets dual-cell configurations, offering a compact solution compared to discrete protection designs. It integrates essential monitoring functions into a single small-footprint package.

Battery Management Replacement Considerations

Direct replacements must match the two-cell serial protection function and TSSOP-8 package. Verify equivalent electrical characteristics, particularly overcharge and overdischarge thresholds. Check for compatible pinouts to ensure board-level interchangeability without redesign. Consult ABLIC's official substitution guides for validated alternatives.
