HYBRID IC
VLA551K-01R
DRIVER FOR IGBT MODULES
DESCRIPTION
VLA551K-01R is a hybrid integrated circuit designed for driving n-channel IGBT modules in any gate-amplifier application.
OUTLINE DRAWING
This device include the isolated type DC-DC converter for a Gate drive. Therefore design of the gate power supply is not

required.
The system of built-in short circuit protection provide a margin
to time by function to maintain reverse bias for a predetermined
time after the detection of short circuit.
Recommended IGBT modules: VCES=600V series up to 600A class VCES=1200V series up to 450A class VCES=1700V series up to 400A class
FEATURES
•Built-in the isolated type DC-DC converter for gate drive
