• Power control
DESCRIPTION
• Data acquisition
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.
• ATE
• Isolated switching
Note
• See “Solid-State Relays” (application note 56)

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.

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.
