VLA546-01R Datasheet, PDF (1/7 Pages) Isahaya Electronics Corporation – Electrical isolation between input and output with opto-coupler

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:
V_CES = 600V series up to 600A class
V_CES = 1200V series up to 400A class
V_CES = 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
