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.

The voltage change becomes big according to an excessive current, and the current of the bias in IC is

turned off temporarily. It is this inﬂuence, and there is a possibility that the output logic becomes unstable.

In that case, please set the time constant of CR connected with the power supply terminal so that the variation

in power source may become 1V/100µsec or more.

The constant of the mark is a standard.

When connecting a battery, it is recommended to make a short circuit by connecting a jumper between the

output and VSS and then remove the output jumper at the completion of installing all the cells.
