[Outline]
This IC is used to control charging of lithium-ion batteries. It is a one-chip charge control IC where the protection circuit incorporates constant-current/constant-voltage charge and precharge, overcharge timer, and battery temperature detection functions. It was developed by adding the above-described functions to the conventional MM1332 and MM1333.
