DESCRIPTION

VLA500-02 is a hybrid integrated circuit designed for driving n-channel IGBT modules in any gate-amplifier application.

This device include the isolated type DC-DC converter for a Gate drive. Therefore design of the gate power supply is not required.

The system of built-in short circuit protection provide a margin to time by function to maintain reverse bias for a predetermined time after the detection of short circuit.

Recommended IGBT modules:

VCES=600V series up to 600A class

VCES=1200V series up to 1400A class

FEATURES

•Built-in the isolated type DC-DC converter for gate drive

•SIP outline allows more space on mounting area

•Built-in short circuit protection (With fault output)

•Variable fall time on activity of short circuit protection

•Electrical isolation voltage between input and output is 2500Vrms (for 1minute)

•TTL compatible input.

APPLICATIONS

To drive IGBT modules for inverter or AC servo systems application
