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 Lithium-

ion/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.

(Unless otherwise speciﬁed, Topr=+25°C)

Note1 : Overcharge release function is selectable from 3 options (voltage decrease, charger remove, load connect).

Note± : Overdischarge release function is selectable from 3 options(voltage increase , charger remove, load connect).

Note3 : Temperature protection detection temperature accuracy is guaranteed by design.

Detection accuracy may change with the speciﬁcation of the used NTC thermistor.
