The driver output is controlled by means of the efficient infrared LED at the input. When current is applied to the LED, its radiated light stimulates the photodiode array causing it to generate the voltage seen at the outputs. The photodiode array is capable of generating a floating power source with sufficient voltage and current to drive high-power MOSFETs. An integrated turn-off circuit within the photodiode array discharges the external MOSFET's gate when the LED current is removed. This eliminates the need for external ponents to facilitate discharging the gate. The optically coupled technology provides 5000VRMS of input to output isolation. The FDA117 is well suited for use in discrete solid state relay designs and in other isolated switching applications.
