HYBRID IC
VLA542-01R
Hybrid IC for driving IGBT modules
DESCRIPTION
VLA542 is a hybrid integrated circuit designed for driving
n-channel IGBT modules in any gate-amplifier application.
This device operates as an isolation amplifier for these modules
and provides the required electrical isolation between
the input and output with an opto-coupler.
Recommended IGBT modules:
V
CES
= 600V series up to 600A class
V
CES
= 1200V series up to 400A class
26MAX
44 MAX
