S-8241ABTMC-GBTT2G

Battery Management Overview

The S-8241ABTMC-GBTT2G is a single-cell lithium-ion and lithium-polymer battery protection IC manufactured by ABLIC. It integrates high-precision voltage detection circuits and delay circuits to provide overcharge, overdischarge, and overcurrent protection. The device operates within a supply voltage range of 1.5 V to 8 V and supports an output voltage of 4.22 V. It is housed in a compact SOT-23-5 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Battery Management Feature Summary

• Integrates high-precision voltage detection for overcharge, overdischarge, and overcurrent conditions without requiring external capacitors for delay timing.
• Features high-voltage tolerance on the VM and CO terminals to withstand charger connection voltages.
• Includes built-in logic for selectable charging to zero-volt batteries and configurable sleep modes.

Battery Management Applications

• Protection circuits for single-cell lithium-ion rechargeable battery packs
• Safety management for lithium-polymer rechargeable battery modules
• Portable electronic devices requiring integrated cell protection

Battery Management Procurement Notes

Verify the specific suffix GBTT2G against the manufacturer's current datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure the ordering code matches the exact voltage detection thresholds required for your battery chemistry. Cross-reference with official ABLIC documentation to validate RoHS compliance status and environmental certifications before finalizing procurement.

Battery Management Selection Notes

Select this component when designing protection for single-cell Li-ion or Li-Po batteries requiring integrated overcurrent and voltage monitoring. The SOT-23-5 package suits space-constrained applications. Verify that the operating voltage range covers your system's requirements and that the thermal performance meets the application's ambient temperature constraints.

Battery Management Part Context

This part belongs to the S-8241 series of battery protection ICs from ABLIC. The series is designed specifically for safeguarding single-cell secondary batteries. It replaces discrete protection solutions by combining detection and control functions into a single CMOS chip, simplifying circuit design and reducing component count in portable electronics.

Battery Management Replacement Considerations

Check for direct substitutes within the S-8241 family with different voltage thresholds or package options. Verify pin-to-pin compatibility if considering alternatives from other manufacturers. Confirm that replacement parts support the same single-cell architecture and protection logic.
