Description

The R5434 is an overcharge protection IC for 2 to 5 serial Li-ion/Li-polymer secondary battery. When an overcharge is detected, after the IC internally fixed delay time, the output of COUT becomes "H". After detecting the overcharge, when the cell voltage becomes lower than the overcharge release voltage, the overcharge state is released. The output type is CMOS.
