ICPL-3120
2.5A Output Current, High CME
Gate Drive Optocoupler
Description
The ICPL3120 optocoupler is ideally suited
for driving power IGBTs and MOSFETs used
in motor control inverter applications and
inverters in power supply system. It contains
a AlGaAs LED optically coupled to an
integrated circuit with a power output stage.
The 2.5A peak output current is capable of
directly driving most IGBTs with ratings up to
1200 V/100 A. For IGBTs with higher ratings,
the ICPL3120 series can be used to drive a
discrete power stage which drives the IGBT
gate.
