S-8211CBD-I6T1U

Battery Management Overview

The S-8211CBD-I6T1U is a battery protection IC designed for single-cell lithium-ion and lithium-polymer battery packs. It provides secondary protection functions, including overcharge, overdischarge, and overcurrent safeguards. The device operates within a supply voltage range of 1.5 V to 6 V and features low power consumption with an operating current of 600 nA. It is housed in an SNT-6A-6 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Battery Management Feature Summary

• Provides secondary protection for single-cell lithium-ion and lithium-polymer batteries
• Integrates overcharge, overdischarge, and overcurrent detection circuits
• Operates with ultra-low standby current consumption
• Compatible with standard surface-mount assembly processes

Battery Management Applications

• Secondary protection circuits for portable electronic devices
• Battery management systems in consumer electronics
• Protection modules for single-cell lithium-based battery packs

Battery Management Procurement Notes

Verify component authenticity through authorized ABLIC distributors or certified suppliers. Confirm the specific suffix I6T1U matches design requirements for package and tape-and-reel specifications. Check for end-of-life status as some S-8211 variants are marked NRND. Request official datasheets and RoHS compliance documentation before integration into production designs.

Battery Management Selection Notes

Select this component when designing secondary protection for single-cell lithium batteries requiring low quiescent current. Ensure the input voltage range covers the full cell operating spectrum. Verify that the SNT-6A-6 package fits the PCB layout constraints. Compare against primary protection ICs if space or cost is critical, noting this device typically complements rather than replaces primary switches.

Battery Management Part Context

This part belongs to the S-8211C series of battery protection ICs from ABLIC. The series focuses on compact, low-power solutions for single-cell applications. The CBD variant specifically denotes certain threshold characteristics within the family. The I6T1U suffix indicates the SNT-6A-6 package and reel packaging format.

Battery Management Replacement Considerations

Direct substitutes include other S-8211C series variants such as S-8211CCY-I6T1U or S-8211CDP-I6T1U, provided threshold voltages match the design. Cross-reference electrical parameters carefully as different suffixes may alter protection thresholds. Consult ABLIC for updated lifecycle status and recommended alternatives if the part is discontinued.
