Description
The FOD3181 is a 0.5A Output Current, High Speed
MOSFET Gate Drive Optocoupler. It consists of a
gallium aluminum arsenide (AlGaAs) light emitting diode
optically coupled to a CMOS integrated circuit with a
power stage. The power stage consists of a PMOS pull-
up and a NMOS pull-down power transistor. It is ideally
suited for high frequency driving of MOSFETs used in
Plasma Display Panels (PDPs), motor control invertor
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.
