MM3508A series is a double protection IC for 1 to 4 serial cells lithium-ion / lithium-polymer rechargable batteries. It detects battery voltage for each cell. A timer circuit is built in and the detection delay time can be set. The latch function allows the output to be held for a certain period of time at the time of detection and thus keeps the fuse disconnection time constant. The high voltage of cells can be reduced and then stopped to prevent battery from deteriorating by the electric discharge function of the integrated circuit after the fuse is disconnected.
