MM3855 Series

Thermal protection and control terminal for charge and

discharge oﬀ mode protection IC

Outline

MM3855 series are protection ICs with thermal protection and

control teminal for charge and discharge oﬀ mode for Lithium-ion

and Lithium-polymer rechargeable battery.

system over temperature. In addition, it reduces the current

consumption of system by using charge and dischrge oﬀ mode ,

when the system is shutdown.

By using external thermistor, this protects the battery pack and
