MM3783 Series

Lithium-Ion Battery protection IC using high voltage CMOS process for overcharge, overdischarge and overcurrent protection of the rechargeable Lithium-ion or Lithium-polymer battery. The overcharge, overdischarge, discharging overcurrent, charging overcurrent, and short protection of the rechargeable Lithium-ion or Lithium-polymer battery can be detected. Each of these IC composed of four voltage detectors, short detection circuit, reference voltage sources, oscillator, counter circuit and logical circuits.

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.
