1 cell lithium–ion/lithium–polymer battery
protection IC
MC3011 Series
MC3011 series are protection IC with integrated MOS-FET for
protection of the rechargeable lithium-ion or lithium-polymer
battery. The overcharge, overdischarge and discharging and
charging overcurrent protection of the rechargeable one-cell
lithium–ion or lithium–polymer battery can be detected.
