MOSFET Driver

The FDA215 is a dual photovoltac MOSFET driver that uses a pair of optically coupled GaAIAs LEDs to drive two Photodiode arrays. When the input current is applied to the LED the light emitted will activate the Photodiode array and generate a voltage at the output. The Photodiode arrays are capable of gener- ating a floating source voltage and current sufficient to drive high Power MOSFET Transistors The optical coupling provides a high level of input to output isola- tion. The FDA215 is well suited for use in Discrete Solid State Relay designs and other isolated switching applications. By Clare, Inc.
