MM3474P06VBE

Overview

The MM3474P06VBE is a monolithic integrated circuit belonging to the MM3474 series, manufactured by Mitsumi Electric Co Ltd. It functions as a power supply support circuit designed for battery protection applications. The device is housed in a TSSOP20 package with a 0.635 mm pitch and operates within an industrial temperature range of -40 °C to 85 °C. It supports lithium-ion and lithium-polymer rechargeable secondary batteries consisting of 3 to 5 cells.

Feature Summary

• Provides overcharge, overdischarge, and overcurrent protection for multi-cell lithium-ion and lithium-polymer batteries
• Detects short circuits and individual cell voltage anomalies within the battery pack
• Monolithic IC design integrating protection logic for compact system implementation

Applications

• Protection circuits for 3 to 5 cell lithium-ion battery packs
• Protection circuits for 3 to 5 cell lithium-polymer battery packs
• Portable electronic devices requiring multi-cell battery management

Procurement Notes

Verify the specific suffix P06 against official Mitsumi documentation to confirm pinout and functional variations within the MM3474 series. Ensure compatibility with the target battery cell count and operating temperature requirements before integration. Cross-reference datasheet revisions to confirm current manufacturing status and qualification details.

Selection Notes

Select this component when designing protection systems for 3 to 5 series-connected lithium-based cells. The TSSOP20 package suits surface-mount assembly processes. Verify that the maximum supply current and operating temperature range align with the system's environmental constraints and power budget requirements.

Part Context

The MM3474P06VBE 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/polymer batteries. The series utilizes a TSSOP20 package and is classified under power supply support circuits.

Replacement Considerations

MM3474G01VBE and MM3474E02VBE are documented members of the same MM3474 series with identical protective functions for 3-5 cell batteries. Verify pin-to-pin compatibility and specific suffix differences via official datasheets before substitution.
