1)
Max Switching Frequency
2 kHz
2)
Notes:
1)
This is the value define by the driver datasheet. Typical short circuit current is 1 A
when the driver chip is cold and < 0.5 A when the chip temperature has risen due to
the short circuit condition (thermal overload protection)
2)
For ohmic load only. The VN330SP has integrated demagnetization of inductive
loads. Customers wishing to use this features should study the VN330SP datasheet
very carefully and test their application. It is likely that the switching frequency has to
be reduced to reduce dispassion of clamping energy.
