What am I missing?
What will you be switching with this mosfet,and are you going to use a driver chip or a 20mA Arduino pin.Leo..
Solenoid valves from an Arduino pin.
If you actually need those nanosevond turn-on times then you need a driver capable of forcing several amps of current into the gate for those nanoseconds.
OK, so you put a 10k resistor from the Arduino pin to ground to set a default OFF level whilst the Arduino boots, then you put a 220 Ohm resistor from the Arduino pin to the FET gate.Done!
I have a 100 Ohm to the gate. Any reason why a 220 would be required?This is something that has a lot of conflicting information about online. Some say there is no need for a resister, other say you should have one. Some say 50 Ohm is OK, others like larger.
