MM3474G06VBE

Overview

The MM3474G06VBE is a power supply support circuit manufactured by Mitsumi Electric, classified under power management ICs. It is housed in a TSSOP-20 package with a plastic/epoxy body and gull-wing terminals spaced at 0.635 mm. The device operates within an industrial temperature range of -40 °C to +85 °C and has a maximum supply current of 0.02 mA. It is designed for lithium-ion and lithium-polymer battery protection.

Feature Summary

• Monolithic integrated circuit providing overcharge, overdischarge, and overcurrent protection for rechargeable batteries.
• Capable of detecting short circuits across individual cells in multi-cell battery packs.

Applications

• Protection for 3 to 5 cell lithium-ion rechargeable secondary batteries
• Protection for 3 to 5 cell lithium-polymer rechargeable secondary batteries

Procurement Notes
