DESCRIPTION
VLA500-02R 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:
VCES=600V series up to 600A class
VCES=1200V series up to 1400A class

PRECAUTION
(1) Voltage compensate capacitors are expected to be located as close as possible to the Hybrid IC.
(2) Minimize the area of closed circuit of gate circuit so as not to be affected by induction noise.
(3) D1 requires approximately the same voltage of power modules.
(4) When recovery current flow in D1 , pin 30 is applied high voltage .
In that case , counterplan for protection which insert a zener diode between pin21,22 and 30 are necessary like above diagram.
(5) When you make late speed of reverse bias at the time of short circuit protection operation,
please adjust and connect a capacitor between the 21,22 and 27.
