Description
Hybrid Ic For Driving Igbt Modules
Manufacturer
ISAHAYA ELECTRONICS CORPORRATION
Datasheet
DESCRIPTION
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 opto-couplers.
Recommended IGBT modules:
FEATURES
•Electrical isolation between input and output with opto-coupler
•Built-in short circuit protection circuit (Soft shut down)
•Built in alarm output opto-coupler
•CMOS compatible input interface
