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
rms
of input to output isolation.
The FDA217 is well suited for use in discrete solid
state relay designs and in other isolated switching
applications.
