Hi to all,
After doing some MOSFET research online I realise I don't fully understand how they are turned on. Since all the FETs I have used have always been switching lowish voltages (the most was 30v) I have never come up against what they actually need to saturate with the high voltage ones.
The ones I plan on using are STP9NK60Z N-CHANNEL 600V - 0.85r - 7A and will be switching about 270v dc for a DC universal motor.
I was wondering if I can switch it with the output from a 555 timer for PWM or even from a PIC micro?
Nowhere in the specs does it state the actual voltage or current needed to switch it, and up to now I didn't know it was a concern.
Any help appreciated
Thanks Al
