I Just got some irf520n off ebay (220 pcs for $25)
They seem to be "drivable" , by an AVR Vgs(th) 2.7 - 4v
But as you prob. have discovered im not an electronics wizzard :oops:
I was wondering if i read "curves" at Fig. 1/2/3 correct , if i assume i could switch 3A@20uS with an AVR :?:
Well Fig 3 seems to indicate i can switch 3A @Vgs-5v.
So if i just use it at "low speed" 1..10Hz it moght be ok.
Fig 1 seems to indicate that it can do the same @20uS
But can the AVR drive that or do i need a driver / pushpull ?
What would be a "realistic" A/Freq for driving direct by AVR ?
If i need a driver , can i make one from the below comps ?
I have a reel of 2N7002-LT1 (N-Fet) www.spelektroniikka.fi/kuvat/2N7...
And a reel of BSP225 (P-Fet) http://www.nxp.com/documents/dat...
Thanx for any info ...
