AC adaptor / USB input selector & Li-ion/Ni-MH battery charger
Description
R2J20053NS controls selection of 2 power inputs from AC adaptor and USB.
R2J20053NS can charge a single or two Ni-MH* cells with constant current control, when an AC adaptor or USB
power source is connected. Also, R2J20053NS can charge a single Li-ion cell with constant current or constant voltage
control. (* For Ni-MH, only constant current control can be used and the function of charging completion detector is not included.)
