OLI920

Hybrid Smart Photovoltaic Optocoupler

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.
