MITSUMI 3 cell Lithium-ion/Lithium-polymer battery protection IC MM3783 Series 3 cell Lithium-ion/Lithium-polymer battery protection IC MM3783 Series Outline MM3783 series are an overcharge, overdischarge, overcurrent and temperature protection IC for a Lithiumion/Lithiumpolymer rechargeable battery. Lithium-ion/Lithium-polymer battery overcharge each cell, over discharge, and discharge and charging overcurrent, short circuits can be detected. The detection of the temperature is enabled by connecting resistance between thermistor, TH terminal -VSS terminals between REG terminal -TH terminals. Each of these IC composed of six voltage detectors, short detection circuit, reference voltage sources, delay time generation circuit , logical circuits and regulator circuit etc.
