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.
