Features

Applications

Description

The IX3120 gate driver includes an input infrared LED

that is optically coupled to a power output stage. The

power output stage is capable of sourcing or sinking

2A of peak current, which is ideal for driving IGBTs

and MOSFETs in the mid-power range.

The gate driver optocoupler with its low input LED

current, high output peak current, and high noise

immunity (25kV/

s) is ideally suited for use in motor

control and inverter applications.

The IX3120 is provided in an 8-pin DIP package and

an 8-pin surface mount package.
