Overview
The FOD3182SD is a 3A output current, high-speed MOSFET gate drive optocoupler produced by onsemi. It consists of an aluminium gallium arsenide (AlGaAs) light emitting diode optically coupled to a CMOS detector with PMOS and NMOS output power transistors integrated circuit power stage. This device is ideally suited for high frequency driving of power MOSFETS used in various applications such as Plasma Display Panels (PDPs), motor control inverter applications, and high performance DC-DC converters. The FOD3182SD is packaged in an 8-pin dual in-line housing compatible with 260°C reflow processes for lead free solder compliance.
