MM3474M01VBE

Overview

The MM3474M01VBE is a power supply support circuit manufactured by Mitsumi Electric Co Ltd. It is housed in a TSSOP20 package with a dual gull-wing terminal configuration and a 0.635 mm pitch. The device operates within an industrial temperature range of -40 °C to 85 °C. It features a maximum supply current of 0.02 mA and utilizes plastic/epoxy encapsulation. This component functions as a protection IC for lithium-ion and lithium-polymer rechargeable secondary batteries, specifically designed for 3 to 5 cell configurations.

Feature Summary

• Provides overcharge, overdischarge, and overcurrent protection for lithium-ion and lithium-polymer batteries
• Detects short circuits and individual cell voltage anomalies in multi-cell battery packs
• Monolithic integrated circuit design for compact implementation

Applications

• Protection circuits for 3 to 5 cell lithium-ion battery packs
• Protection circuits for 3 to 5 cell lithium-polymer battery packs
• Consumer electronics requiring multi-cell battery safety management

Procurement Notes

Verify the specific suffix 'M01VBE' against official Mitsumi documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the TSSOP20 footprint aligns with your PCB layout. Confirm that the industrial temperature rating (-40 °C to 85 °C) meets your operational environment specifications. Cross-reference the ECCN code EAR99 for export compliance needs.

Selection Notes

Select this component when designing protection systems for 3 to 5 series connected lithium-based cells. The TSSOP20 package is suitable for surface mount applications requiring a compact form factor. Consider the low supply current of 0.02 mA for battery efficiency. Verify compatibility with the specific cell chemistry (Li-ion or Li-Po) supported by the monolithic IC architecture.
