HYBRID IC
VLA520-01R
Hybrid IC for driving IGBT modules
DESCRIPTION
VLA520 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
Recommended IGBT modules:
