The FDA217 is a dual photovoltaic MOSFET driver.

Each independent driver consists of an LED that is

optically coupled to a photodiode array.

The driver output is controlled by means of the highly

effective GaAlAs infrared LED at the input. When the

input current is applied to the LED, the light emitted

activates the photodiode array, and generates the

voltage at the output.

The photodiode array is capable of generating a

floating power source with voltage and current

sufficient to drive high-power MOSFET transistors.

Each photodiode array contains an integrated

turn-off circuit that discharges the external MOSFET

gate when LED current is removed. This eliminates

the need to use external components to facilitate the

discharge. The optically coupled technology provides

3750V

The FDA217 is well suited for use in discrete solid

state relay designs and in other isolated switching

applications.
