VLA567-02R
DRIVER FOR IGBT MODULES
DESCRIPTION
VLA567-02R is the hybrid integrated circuit of 2ch IGBT drivers.
This device include the isolated type DC-DC converter for
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.
Targeted IGBT modules:
VCES = 600V series up to 600A class
VCES = 1200V series up to 600A class
(Please keep the condition not to deviate from the recommended
range of electrical characteristics and maximum rating. )
FEATURES
Low height, DIP structure
Built in the isolated DC-DC converter for gate drive
Output peak current is +/-8A(max)
Built in short circuit protection
Electrical isolation voltage is 2500Vrms (for 1 minute)
CMOS compatible input interface
Adjustable fall time on activity of short circuit protection.
