MM3625

MITSUMI 3 to 4 cell Lithium-ion/Lithium-polymer battery secondaryr potection protection IC MM3625 Series 3 to 4 cell Lithium-ion/Lithium-polymer battery secondaryr potection protection IC MM3625 Series Outline The MM3625 series are secondary protection IC using high voltage CMOS process for overcharge protection of the rechargeable Lithium-ion or Lithium-polymer battery. The high accuracy overcharge detection of each cell ofthe rechargeable 3 to 4 cell Lithium-ion or Lithiumpolymer battery is possible. The IC has a regulator and it ispossible to stop regulator by detected overdischarge. The internal circuit of IC is composed by the voltagedetector, the reference voltage source, delay time control circuit, the logical circuit, and regulator circuit etc. Features (Unless otherwise specified, Topr=+25°C) (1) Range and accuracy of detection/release voltage Overcharge detection voltage 3.6V to 4.5V, 5mV steps Overcharge release voltage 3.4V to 4.5V, 50mV steps VOU OFF voltage 2....
