4V Output Solar Cell
CPC1822
Open Circuit Voltage Short Circuit Current
* Direct sunlight (Approximately 6000 lux)
CPC1822 4 50
Units V uA
Description
The CPC1822 is a monolithic photovoltaic string of solar cells with switching circuitry. When operating in sunlight or a bright artificial light environment the optical energy will activate the cell array and generate a voltage at the output. The solar cells are capable of generating a floating source voltage and current sufficient to drive and power CMOS IC's, logic gates and/or provide "trickle charge" for battery applications.
