VLA539-01R Datasheet, PDF (1/6 Pages) Isahaya Electronics Corporation – DRIVER FOR IGBT MODULES

PRELIMINARY
DESCRIPTION
VLA539 is a hybrid integrated circuit designed for driving
n-channel IGBT modules in any gate-amplifier application.
OUTLINE DRAWING
Electrical isolation voltage between input and output is 4000Vrms
(for 1minute).This device include the isolated type DC-DC
88.0 MAX
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 3600A class
V_CES = 1700V series up to 3600A class
