Description
The LH1262CB/CAC Photovoltaic MOSFET Driver
consists of two LEDs optically coupled to two photo-
diode arrays. The photodiode array provides a float-
ing 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.

1) f = 1.0 kHz, pulse width = 100 µs, load (RL) = 1.0 M, 15 pF; measured at 90 % rated voltage (ton), 10 % rated voltage (toff). Actuation
speed depends upon the external ton and toff circuitry and the capacitance of the MOSFET.
Functional Description
Figure 1 outlines the IV characteristics of the illumi-
nated photodiode array (PDA). For operation at volt-
ages 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.
