Overview
The MM3474F06VBE is a monolithic power supply support circuit designed for battery protection, manufactured by Mitsumi Electric Co Ltd. It belongs to the MM3474 series and is specified as a Power Supply Support Circuit in a PDSO20 package. The device features a TSSOP-20 (TSSOP20,.25) plastic/epoxy housing with gull-wing terminals arranged in a dual configuration at a pitch of 0.635 mm. It operates within an industrial temperature range from -40 °C to 85 °C. The maximum supply current (Isup) is 0.02 mA. The component supports surface mount technology and is classified under ECCN code EAR99.
Feature Summary
- Provides integrated overcharge, overdischarge, and overcurrent protection functions for rechargeable secondary batteries.
- Capable of detecting short circuits and monitoring individual cell conditions within multi-cell battery packs.
- Designed specifically for compatibility with lithium-ion and lithium-polymer battery chemistries.
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
Procurement Notes
Verify that the specific suffix F06 corresponds to the intended voltage or functional variant, as datasheet documentation primarily references the general MM3474 series. Confirm the TSSOP-20 package dimensions and terminal pitch match the target PCB layout. Ensure the industrial temperature rating (-40 °C to 85 °C) meets the operational requirements of the final application environment. Cross-reference the manufacturer's official ordering information to validate part availability and revision status.
Selection Notes
Select this component when designing protection logic for multi-cell lithium-based battery systems requiring integrated fault detection. The low supply current consumption makes it suitable for applications where standby power efficiency is critical. Consider the TSSOP-20 footprint constraints during PCB design. Verify that the single-chip solution covers all necessary protection thresholds for the specific battery chemistry used, eliminating the need for discrete comparator components.
