2 to 4cell Li-ion/Li-polymer battery Secondary protection IC
MM3508A Series
Outline
MM3508A series is a double protection IC for 1 to 4 serial cells lithium-ion / lithium-polymer rechargable battery for secondary protection IC.
It detects battery
voltage for each cell.
The FUSE cutting signal is the output between period of time.
And the CELL
voltage is released by electric discharge after FUSE was cut.
