MM3474C04VBE

Overview

The MM3474C04VBE is a monolithic integrated circuit belonging to the MM3474 series, manufactured by Mitsumi Electric Co Ltd. It functions as a protection IC designed for lithium-ion and lithium-polymer rechargeable secondary batteries with 3 to 5 cells. The device detects overcharge conditions for each individual cell, as well as overdischarge, discharge overcurrent, and short circuits within the battery pack.

Feature Summary

• Monolithic integration of protection functions for multi-cell lithium-based battery packs
• Detection capability for per-cell overcharge, overall overdischarge, and discharge overcurrent events
• Short circuit detection functionality included within the protection logic

Applications

• Protection circuits for 3 to 5 cell lithium-ion battery packs
• Protection circuits for 3 to 5 cell lithium-polymer battery packs
• Rechargeable secondary battery management systems requiring cell-level monitoring

Procurement Notes

Verify the specific suffix C04 against official Mitsumi documentation to confirm exact electrical characteristics and pinout compatibility. Ensure the component matches the required cell count range of 3 to 5 cells. Confirm package type TSSOP20 availability and industrial temperature rating compliance before procurement.

Selection Notes

Select this component when designing protection for 3 to 5 cell lithium-ion or lithium-polymer batteries. It provides comprehensive detection for overcharge, overdischarge, overcurrent, and short circuits. Consider the TSSOP20 package constraints and industrial temperature range requirements during board layout and thermal design.

Part Context

The MM3474C04VBE is part of the MM3474 series from Mitsumi Electric Co Ltd. This series includes variants such as MM3474G01VBE and MM3474E02VBE, all sharing the core function of protecting 3 to 5 cell lithium-ion/lithium-polymer batteries. The series is characterized by its ability to detect per-cell overcharge and system-level faults like overdischarge and short circuits.

Replacement Considerations

MM3474G01VBE and MM3474E02VBE are documented members of the same MM3474 series offering similar protection functions for 3 to 5 cell lithium batteries. Verify pinout and specific electrical parameters before substitution.
