VLA552-01R Datasheet, PDF (1/9 Pages) Isahaya Electronics Corporation – Built-in short circuit protection

DESCRIPTION
VLA552-01R 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 = 1200V series up to 3600A class
V_CES = 1700V series up to 3600A class
FEATURES
•Built-in the isolated type DC-DC converter for gate drive
•SIP outline allows more space on mother board

•Possible to assist collector clamp circuit
•Variable fall time on activity of short circuit protection
•Electrical isolation voltage between input and output is 4000Vrms (for 1minute)
•CMOS compatible input.
APPLICATIONS
To drive IGBT modules for general industrial use apparatus.
