Overview
The FOD3182SDV, produced by onsemi, is a 3A output current, high-speed MOSFET gate drive optocoupler. This device consists of an aluminium gallium arsenide (AlGaAs) light emitting diode (LED) optically coupled to a CMOS detector with PMOS and NMOS output power transistors integrated circuit power stage. It is designed for high frequency driving of power MOSFETs, making it ideal for applications such as Plasma Display Panels (PDPs), motor control inverter applications, and high performance DC-DC converters. The FOD3182SDV is packaged in an 8-pin dual in-line housing compatible with 260°C reflow processes for lead free solder compliance.
