Good Idea. Those guys want you to succeed, because when you do, they do
Or talk to the Application Engineers. In either case, that may be your best route to go. The people that design, or sell the product know best... Usually.
You could always use a current loop or something.
No. You need a logic level FET for this. A IRLZ44 will work.Can I switch ON/OFF FET IRFZ44N directly (through resistor) from the output pin of 89C2051 microcontroller?
No. You need a logic level FET for this. A IRLZ44 will work.
If Kchriste suggested it then I would say your good to go.

He didn't suggest. I am just asking.
Oh, but I think he did... I think your ok with that fet.

Eliminate R7 if the 12V isn't going any higher; The gate is good to 20V, but it's nice to have some headroom if needed. Because the 89C2051 can only source 80uA at 2.4V, you should also increase the value of R6 to 10K or so, but this will slow the switching time of the circuit somewhat. I'm not that familiar with the 89C2051, but you may have to add a pull up resistor on the IO pin to supply enough current for the transistor if you want faster switching speeds. How fast do you need to switch the load on and off?
Simply look on the datasheet for the AT89C2051 micro-controller to see that its max allowed voltage on any pin is +7.0V and that your R9 is connected to +12V which might destroy it.
R9 should be connected to the +5V supply of the micro-controller.
Since you cannot get a logic-level Mosfet then test many of the ordinary Mosfets to find one that works with an input of 5V.
I got that one and get millions of other datasheets from Datasheet Archive - Free Datasheet Search Engine :: PDF Datasheets :: Data Sheet :: Datasheet :: Application Note : çš„å‚æ•° : 规æ*¼ä¹¦ : 技术资料 : ë°ì´í„°ì‹œíŠ¸ : データ・シート : Fiche technique : Datenblatt : опиÑание .
They have a limit of about 25 per day but my router gives them a different address each time so I have no limit.
I have the data sheet of ATMEL and I couldn't find this 7V limit on all pins. That is why I asked. A useful discussion was going on. I think it is better to avoid posts just for the sake of increasing counts.
