VLA541-01R Datasheet, PDF (1/5 Pages) Isahaya Electronics Corporation – Hybrid IC for driving IGBT modules

TENTATIVE
DESCRIPTION
VLA541 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 200A class
V_CES = 1200V series up to 150A class
FEATURES
•Electrical isolation between input and output with opto-coupler
(Viso = 2500Vrms for 1minute)
•Two supply driver topology
•Built-in short circuit protection circuit(With a pin for fault out)
•CMOS compatible input interface
