Lithium-Ion Battery protection IC using high voltage CMOS process for overcharge, overdischarge and overcurrent protection of the rechargeable Lithium-ion or Lithium-polymer battery. The overcharge, overdischarge, discharging overcurrent, charging overcurrent, and short protection of the rechargeable Lithium-ion or Lithium-polymer battery can be detected. Each of these IC composed of four voltage detectors, short detection circuit, reference voltage sources, oscillator, counter circuit and logical circuits.

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.
