1 cell lithium–ion/lithium–polymer battery
protection IC
MC3651 Series
MC3651 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.
