DESCRIPTION
The VOW3120 consists of an infrared light emitting diode
optically coupled to an integrated circuit with a power
output stage. This optocoupler is ideally suited for driving
power IGBTs and MOSFETs used in motor control and
inverter applications. The high operating voltage range of
the output stage provides the drive voltages required by
gate controlled devices. The voltage and current supplied by
this optocoupler makes it ideally suited for directly driving
IGBTs with ratings up to 1200 V/100 A. For IGBTs with
higher ratings, the VOW3120 can be used to drive a discrete
power stage which drives the IGBT gate.
The VOW3120 provides higher isolation for applications
operating at higher working voltages, and or higher pollution
degree criteria. Higher VIORM, VIOTM, creepage and
clearance distances, make the VOW3120 ideal for many
industrial control and power conversion applications.
