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.
