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:
VCES = 600V series up to 200A class VCES = 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
