Lithium-Ion Battery Charge Control (1 to 2 cells)

Monolithic IC MM1433

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.
