　MM3508A Series
Description
The MM3508A series is a double protection IC for 2-4 cell Li batteries. It detects battery voltage for each cell. The configuration
of delay time can be achieved. Output at the time of detection can be held for a fixed period of time; therefore, this can maintain
a regular disconnection time of a fuse. In addition, high cell voltage can be dropped and then stopped at the level where battery
deterioration does not occur by Electrical discharge function of the IC after disconnecting the fuse. The ultra-small package SSON-
6A is used to minimize footprints.
Features
The FUSE cutting signal is the output between period of time. And the CELL voltage is released by electric discharge resistance of
"60KΩ" after FUSE was cut.
And CELL stops an electric discharge if the CELL voltage becomes less than the electric discharge release voltage.

Description
The MM3508C series is a double protection IC for 2-3 cell Li batteries. It detects battery voltage for each cell. The configuration
of delay time can be achieved. Output at the time of detection can be held for a fixed period of time; therefore, this can maintain
a regular disconnection time of a fuse. In addition, high cell voltage can be dropped and then stopped at the level where battery

Features
2～3cell Li-ion/Li-polymer battery Secondary protection IC
The terminal CT is used to control the output voltage of the terminal OV.The terminal CT controls the output voltage of the
terminal OV regardless of the overcharge detection circuit.As for the output voltage of the terminal OV, the terminal CT becomes
usually state in "H",and it becomes "H" in Open or "L".・The terminal OV is controlled with the overcharge detection circuit in
usually state.
