MM3508A05RRE

Overview

The MM3508A05RRE is a secondary protection integrated circuit designed for lithium-ion and lithium-polymer battery packs containing two to four cells. Manufactured by Mitsumi Electric, this component provides essential safety functions within the battery management system. It operates as an active product currently available for integration into portable electronic devices requiring reliable cell monitoring and protection against over-voltage, under-voltage, and over-current conditions.

Feature Summary

• Provides secondary protection for multi-cell lithium-based battery architectures
• Supports configurations with two to four series-connected cells
• Integrates protection logic for lithium-ion and lithium-polymer chemistries

Applications

• Lithium-ion battery pack protection circuits
• Lithium-polymer battery management systems
• Portable electronic device power supplies

Procurement Notes

Verify the specific suffix RRE matches the required tape and reel packaging configuration. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Ensure the design supports the 2-4 cell voltage range specified for this secondary protection IC variant from Mitsumi Electric.

Selection Notes

Select this component when designing protection circuits for 2S to 4S lithium battery configurations. The MM3508A05RRE serves as a secondary protection layer, complementing primary protection mechanisms. Verify that the application requires a dedicated secondary protection IC rather than a combined primary/secondary solution.

Part Context

This part belongs to the MM3508 family of battery protection ICs from Mitsumi Electric. Variants such as MM3508A07RRE and MM3508B07RRE exist within the same product line, offering different protection thresholds or features for similar multi-cell applications. The MM3508A05RRE specifically targets standard lithium-ion and polymer cell protection requirements.

Replacement Considerations

Direct substitutes include other MM3508 series variants like MM3508A07RRE or MM3508B07RRE, provided their specific protection parameters align with the design requirements. Cross-referencing datasheets is necessary to ensure compatibility with the target cell count and voltage levels.
