VLA500-02 Datasheet, PDF (1/6 Pages) Isahaya Electronics Corporation – DRIVER FOR IGBT MODULES

DESCRIPTION
VLA500-02 is a hybrid integrated circuit designed for driving
n-channel IGBT modules in any gate-amplifier application.
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:
V_CES=600V series up to 600A class
V_CES=1200V series up to 1400A class
