R5434D402AA R5434D 2 Cell Battery Charger IC Power Manager IC

R5434D402AA overcharge protection IC R5434D Series Li-Ion Li-Polymer Battery Protection PMIC for Secondary Protection

Details:  R5434D Series Battery Management 2-Cell to 5-Cell Protection PMIC-Power manager IC

OUTLINES:

The R5434D 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. By forcing VDD+3.0V or more to the CTLC pin, the test time of protection circuit board can be shortened, and overcharge delay time becomes about 1/30. The output type is CMOS.
