Description

The FOD8343 series is a 4.0 A maximum peak output current gate

drive optocoupler, capable of driving medium−power IGBT /

MOSFETs. It is ideally suited for fast−switching driving of power

IGBT and MOSFET used in motor−control inverter applications, and

high−performance power systems.

The FOD8343 series utilizes stretched body package to achieve

8 mm creepage and clearance distances (FOD8343T), and optimized

IC design to achieve reliably high−insulation voltage and high−noise

immunity.

The FOD8343 series consists of an Aluminum Gallium Arsenide

(AlGaAs) Light−Emitting Diode (LED) optically coupled to an

integrated circuit with a high−speed driver for push−pull MOSFET

output stage. The device is housed in a stretched body, 6−pin, small

outline, plastic package.
