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.

Moisture Sensitivity
Clare has characterized the moisture reflow sensitivity
of this package, and has determined that this
component must be handled in accordance with
IPC/JEDEC standard J-STD-033 moisture sensitivity
level (MSL), level 3 classification.
Soldering Reflow Profile
For proper assembly, the component must be
processed in accordance with the current revision
of IPC/JEDEC standard J-STD-020. Failure to
follow the recommended guidelines may cause
permanent damage to the device resulting in impaired
performance and/or a reduced lifetime expectancy.
Washing
Clare does not recommend ultrasonic cleaning or the
use of chlorinated solvents.
