![]() ![]() On the output side, pin 5 and pin 8 are connected to a power supply typically 5 volts. FOD3180 detects it through the embedded CMOS detector. The IR radiation is emitted proportional to the current. In above circuit diagram pulse generator is connected to the infrared LED along with two 100 ohms resistors will produce digital rectangular signals whereas these resistors protect the IR LED and also provide control to switching of the device. The figure provided below is the schematic of the FOD3180 MOSFET Gate Driver Optocoupler which takes in an AC input and provides two AC or DC outputs that are electrically isolated. FOD3180 MOSFET Gate Optocoupler Example Circuit It also has a 15kV common-mode rejection to terminate common-mode signals. The optocoupler is embedded with Under Voltage Protection with hysteresis to avoid brownout.
