MM3855 series are protection ICs with thermal protection and control terminal for change and discharge off mode for Lithium-ion and Lithium-polymer rechargeable battery. By using external thermistor, this protects the battery pack and system over temperature. In addidtion, it reduces the current consumption of system by using charge and discharge off mode, when the system is shutdown.
