S-8244AATFN-CETT2G

Battery Management Overview

The S-8244AATFN-CETT2G is a battery protection IC from ABLIC Inc. designed for lithium-ion batteries. It supports 1 to 4 cells in series. The device provides overcharge detection with an accuracy of ±25 mV at +25°C, covering a range from 3.700 V to 4.550 V. It operates within a voltage range of 2 V to 16 V and functions between -40°C and +85°C. The component is housed in an 8-MSOP surface-mount package.

Battery Management Feature Summary

• Internal high-precision voltage detector circuit for accurate overcharge monitoring
• Supports protection for single-cell to four-cell serial lithium-ion battery configurations
• Surface-mount design compatible with standard assembly processes

Battery Management Applications

• Lithium-ion battery pack protection
• Portable electronic devices requiring cell balancing or protection
• Power tools with multi-cell battery systems

Battery Management Procurement Notes

Verify the specific suffix CEQT2G against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 8-MSOP variant. Confirm RoHS3 compliance status if required by your manufacturing standards. Check lifecycle status as components may transition to end-of-life phases.

Battery Management Selection Notes

Select this part when precise overcharge detection is critical for 1 to 4 series lithium-ion cells. The wide operating temperature range suits industrial and consumer applications. Ensure the input voltage range aligns with the total battery stack voltage. Verify that the MSOP package fits the available board space and thermal requirements.

Battery Management Part Context

This IC belongs to the S-8244 series of battery protection devices. The series focuses on high-accuracy voltage detection for multi-cell lithium-ion packs. Other variants in the family may offer different packages or slight parameter variations, but share the core protection functionality.

Battery Management Replacement Considerations

Direct substitutes include other S-8244 series variants such as S-8244AAUFN-CEUT2S or S-8244AAFFN-CEFT2G, provided the package and electrical parameters match the design requirements.
