Description
The FOD3184 is a 3A Output Current, High Speed
MOSFET/IGBT Gate Drive Optocoupler. It consists of a
aluminium gallium arsenide (AlGaAs) light emitting diode
optically coupled to a CMOS detector with PMOS and
NMOS output power transistors integrated circuit power
stage. It is ideally suited for high frequency driving of
power MOSFETS/IGBT used in Plasma Display Panels
(PDPs), motor control inverter applications and high
performance DC/DC converters.
The device is packaged in an 8-pin dual in-line housing
compatible with 260°C reflow processes for lead free
solder compliance.
