Protection for Lithium-Ion Batteries

MM415x Series

Outline

MM415x series are protection ICs with thermal protection and control teminal for charge and discharge off mode for rechargeable Lithium-ion or Lithium-polymer battery.
By using external thermistor, this protects the battery pack and system over temperature. In addition , it reduces the current consumption of system by using charge and dischrge off mode , when the system is shutdown.

Product Series

For one-cell
