MM3508A03RRE

Overview

The MM3508A03RRE is a secondary protection integrated circuit designed for lithium-ion and lithium-polymer battery packs containing two to four cells. Manufactured by Mitsumi Electric Company Ltd, this component provides essential safeguards against overcharge, overdischarge, and overcurrent conditions. It is housed in a compact 6-WFDFN exposed pad package with surface mount technology, making it suitable for space-constrained portable electronic applications requiring reliable battery management.

Feature Summary

• Provides secondary protection functions for multi-cell lithium-based battery systems
• Safeguards against electrical faults including overvoltage, undervoltage, and excessive current
• Designed for surface mount assembly in compact electronic devices

Applications

• Lithium-ion battery pack protection
• Lithium-polymer battery management systems
• Portable consumer electronics

Procurement Notes

Verify the specific suffix '03' corresponds to the required voltage thresholds and timing parameters for your design. Confirm the package type matches your PCB footprint requirements. Ensure compatibility with the target cell count range of two to four cells before procurement.

Selection Notes

Select this component when a dedicated secondary protection IC is required for 2S to 4S lithium battery configurations. Consider the 6-WFDFN package size relative to available board space. Verify that the internal protection thresholds align with the specific chemistry and maximum ratings of the connected battery cells.

Part Context

This part belongs to the MM3508 series of battery protection ICs from Mitsumi. The series includes variants such as MM3508A07RRE and MM3508C02NRH, which share similar functional architectures but may differ in specific electrical characteristics or packaging options tailored for different battery pack configurations.

Replacement Considerations

Cross-reference with other MM3508 series variants like MM3508A07RRE if parameter adjustments are needed. Verify pinout compatibility and thermal performance before substituting with components from other manufacturers offering similar secondary protection functions.
