MM3563B02NRH

Overview

The MM3563B02NRH is a battery protection integrated circuit manufactured by Mitsumi Electric Company Ltd. It is designed for the protection of lithium-ion and lithium-polymer batteries. The device functions as a secondary protection IC, providing over-voltage fault protection to ensure battery safety. It is available in an SOT-26A surface-mount package.

Feature Summary

• Provides secondary protection for lithium-ion and lithium-polymer battery cells
• Detects and responds to over-voltage conditions to prevent cell damage

Applications

• Lithium-ion battery pack protection
• Lithium-polymer battery management systems
• Portable electronic devices requiring cell-level safety monitoring

Procurement Notes

Verify the specific datasheet version from Mitsumi Electric Company Ltd to confirm exact electrical thresholds and pin configurations. Ensure the SOT-26A package matches your PCB footprint requirements. Cross-reference with authorized distributors to confirm component authenticity and traceability before procurement.

Selection Notes

Select this component when secondary over-voltage protection is required for single-cell lithium-based battery applications. Confirm compatibility with the system's voltage range and the specific SOT-26A package constraints. Evaluate if the integrated protection features meet the safety standards of the target end-product.

Part Context

This part belongs to the MM3563B series of battery protection ICs from Mitsumi. Variants such as MM3563B03NRH and MM3563B04NRH exist within the same family, offering similar protection functions but potentially differing in specific parameters or packaging options. The series targets reliable battery management in portable electronics.

Replacement Considerations

Direct substitutes include other models within the MM3563B series, such as MM3563B03NRH or MM3563B04NRH, provided they match the required protection logic and package type. Verify functional equivalence through official datasheets before substitution.
