MM3645, 1cell Lithium-ion/Lithium-polymer battery protection

MITSUMI 1cell Lithium-ion/Lithium-polymer battery protection IC MM3645 Series 1cell Lithium-ion/Lithium-polymer battery protection IC MM3645 Series Outline MM3645 series are protection ICs for Lithium-ion or Lithium-polymer secondary battery using high voltage CMOS process.

They protect the battery pack/system from overcharge, overdischarge, and overcurrent, etc.

by controlling FET SW.

They realize overcurrent detection with high accuracy and improved temperature dependence by using an extern
