![]() ![]() The capacitor represents the gate to source capacitance of a power MOSFET transistor. The load (pin7) consists of a capacitor in series with a current limiting resistor. The Capacitor 0.1uF is a bypass capacitor between pins 5 and 8. ![]() The application circuit for FOD3180 is shown below. It is ideally suited for high-frequency driving of power MOSFETs used in Plasma Display Panels (PDPs), motor control inverter applications, and high-performance DC-DC converters.Įven though FOD3180 is capable of working with both AC and DC it is commonly used with Digital circuits and works with 5V as supply voltage. The operating voltage range for FOD3180 is 10V to 20V and the transistor has an output current of 8mA making it suitable to drive medium level loads. As we know the term Optocoupler means we use light to indirectly couple (isolate) two sets of circuits. Note: More details can be found at the FOD3180 datasheet which is available for download at the end of this page.Īlternatives Optocouplers: MOC3021 (Zero-crossing), MCT2E (non-Zero transistor), MOC3041 (Non-Zero Cross TRIAC), FOD3180 (High-Speed MOSFET), PC817, 4N25, 6N137
