Description
The FOD3182 is a 3A Output Current, High Speed
MOSFET 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 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.
