HYBRID IC
VLA551-01R
DRIVER FOR IGBT MODULES
DESCRIPTION
VLA551-01R 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 450A class

OPERATION OF PROTECTION CIRCUIT
(1) In case the gate voltage is “H” and the collector voltage is high,
this Hybrid IC will recognize the circuit as short circuit and immediately
reduce the gate voltage . Besides, put out a fault sign (“L”) which
inform that protection circuit is operating at the same time from pin 20.
(2) The protection circuit reset and resorted to ordinary condition if input
sign is “L” when the predetermined time(1 ~ 2ms) passed.
(“L” period needs 15us or more )
(3) When the output rises, the controlled time detect short circuit
(Typ 2.7us) is set up so that on-time of IGBT can be secured properly.
It is possible to adjust that time by connecting the capacitor (Ctrip)
between pin 16 and 21.

ADJUSTMENT OF OUTPUT FALL TIME
(When the protection circuit is operating)
In case you want to decrease the speed of reverse bias when the
protection circuit is operating, you can adjust that speed by connecting
the capacitor (Cs) between pin 16 and 18.
