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)

(4) Instructions and directions for use
· When the current pathway of the charge and the discharge is separated, wiring is separated from the
drain of charge and discharge control FET.
· When the current pathway of the charge and the discharge is separated, do not connect load and
charger at the same time. It may incorrect-release from the discharging overcurrent detection state and
the short detection state.
· When the current pathway of the charge and the discharge is separated, please be sure to connect
capacitor (C5) of more than ꢀ.1uF to between the drain and the source of charge control FET.
· If temperature protection function is repealed, please make TH pin and VDD pin connection and make a
REG pin open.
· Temperature detection property is adjusted using the thermo sensitive register of the following part
number, and resistance accuracy. In order to satisfy the characteristic of specification, it recommends
using the following parts.
