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.
