The OLI920 consists of a pair of LEDs that are optically coupled to
a dielectrically isolated photovoltaic diode array, packaged on a
thick film ceramic substrate. When the LED is energized, the
infrared emission is detected by the photovoltaic array and a DC
output voltage is generated. This electrically isolated voltage can
be used to drive the gates of Metal Oxide Semiconductor (MOS)
devices. Additional control circuitry provides fast turn-off,
protection for false turn-on, and gate protection.
Surface mounting can be accomplished with conductive epoxies
or reflow soldering.
