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.

FUNCTIONAL DESCRIPTION
Figure 1 outlines the IV characteristics of the illuminated photodiode array (PDA). For operation at voltages below VOC, the PDA
acts as a nearly constant current source. The actual region of operation depends upon the load.
The amount of current applied to the LED (pins 1 and 2 or 3 and 4) determines the amount of light produced for the PDA. For
high temperature operation, more LED current may be required.
