MM3474C03VBE

Overview

The MM3474C03VBE is a monolithic integrated circuit designed as a protection device for lithium-ion and lithium-polymer rechargeable secondary batteries. It supports battery packs consisting of three to five cells. The component provides comprehensive protection against overcharge, overdischarge, discharge overcurrent, and short circuits for each individual cell within the series. It is housed in a TSSOP20 package with a shrink pitch and operates within an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Monolithic IC architecture for multi-cell battery protection
• Detects overcharge, overdischarge, and discharge overcurrent conditions
• Provides short circuit detection capabilities

Applications

• Lithium-ion battery pack protection systems
• Lithium-polymer battery pack protection systems
• Multi-cell rechargeable secondary battery management

Procurement Notes

Verify the specific suffix 'C03' against official Mitsumi documentation to confirm exact voltage thresholds or binning variations. Ensure the TSSOP20 package dimensions match the target PCB footprint. Confirm that the industrial temperature rating meets the operational requirements of the intended environment before finalizing procurement.

Selection Notes

Select this component when designing protection circuits for 3 to 5 cell lithium-based battery configurations. It is suitable for applications requiring integrated detection of charge, discharge, and short circuit faults without external discrete sensing components. Consider the TSSOP20 package size and industrial temperature range during layout planning.
