2.5A Output Current Gate Driver
Optocoupler
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.
