The VO1263AB and VO1263AAC photovoltaic MOSFET driver consists of two LEDs optically coupled to two photodiode arrays. The photodiode array provides a floating source with adequate voltage and current to drive high-power MOSFET transistors. Optical coupling provides a high I/O isolation voltage. In order to turn the MOSFET off, an external resistance (gate-to-source) is required for gate discharge.

High open circuit voltage, up to 14.6 V typical
High short circuit current, up to 42 μA typical
Isolation test voltage 5300 VRMS
APPLICATIONS:
