VLA542-01R
DESCRIPTION
VLA542 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. Remended IGBT modules:
VCES = 600V series up to 600A class VCES = 1200V series up to 400A 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 patible input interface
