Description
The FAN7563/FAN7564 is designed for Lithium-ion battery
charger. This controls charging current and voltage of Lith-
ium - ion battery as constant current and constant voltage
control IC and can be used for stand alone charger
(FAN7563) and micom interface charger(FAN7564). In
addition LDO regulator driving output which is integrated
within FAN7564 enables to offer accurate reference voltage
to power supply of micro controller, therefore, it features
increasing stability and efficiency of charger set as well as
minimizing external components of the set. Additionally,
FAN7563/FAN7564 provide the protection functions like
error flag, short circuit protection(LDO), and charging
current control disable.
