I have been reading about FET's a bit and have a few questions:
I'm working with an IRFP450,
Do FET's need any gate current to work?
Is the threshold voltage the minimum gate voltage that will allow maximum current to flow?
I'm trying to build a circuit but I don't know how to figure what resistance I need between a NAND gate and the gate of the IRFP450 FET.
The Voltage is 10V applied to a 4093, the output of the 4093 will be used to drive the IRFP450's gate. On the 4093 datasheet the high level output current at 10V typ is 2.25mA. Do I need to add a resistor or is 2.25ma nothing to worry about?
If so how do I figure the resiatance required? Ohms law???
