DESCRIPTION

The LH1262CB, LH1262CAC 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.
