1 cell lithium–ion/lithium–polymer battery protection
IC
MC3002 Series
MC3002 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.
