DESCRIPTION
VLA546 is a hybrid integrated circuit designed for driving
n-channel IGBT modules in any gate-amplifier application.
This device operates as an isolation amplifier for these modules
and provides the required electrical isolation between
the input and output with an opto-coupler.
Recommended IGBT modules:
VCES = 600V series up to 600A class
VCES = 1200V series up to 400A class
VCES = 1700V series up to 400A class
FEATURES
•Electrical isolation between input and output with opto-coupler
(Viso = 4000Vrms for 1minute)
•Two supply driver topology
•Built-in short circuit protection circuit(With a pin for fault out)
•Variable fall time on activity of short circuit protection.
•TTL compatible input interface

※Don’t input on-sign until the provided (R1×Crev(s)) time
has been exceeded after supplied power to this hybrid IC.
PRECAUTION
(1)Voltage compensate capacitors are expected to be located
as close as possible from the hybrid IC.
・APPLICATION EXAMPLE OF HIGH POWER
(2)D1 requires approximately the same voltage of power modules.
(3)If reverse recovery time of D1 is long, pin1 is applied high voltage.
MODULE
In that case, counterplan for protection which insert a zener
diode between pin 1 and 6 is necessary like above diagram.
4.7ｋΩ
(4)In case pin 2 is operating, the Ctrip is expected to be wired
as close as possible from pin 2 and pin 4.
