CPC1822 4V Output Solar Cell Parameter Open Circuit Voltage Short Circuit Current Rating 4 50 * Direct sunlight (Approximately 6000 lux) Features • • • • • • • • 4V Output Triggers with Natural Sunlight Provides True Wireless Power No EMI/RFI Generation Wave Solderable Replacement of Discrete Components Solid State Reliability Small 8-Pin Surface Mount SOIC 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 ICs, logic gates and/or provide “trickle charge” for battery applications.
