Trying to drive a irf mosfet with a 2n transistor.
HTTP This page has been moved
Hello I can make a circuit where the 2n can drive the leds and the arduino can pwm them and it works great. I also can make a circuit with just a irf driving some leds on 12v and it also works great. My main goal is to power some resistance wire for a heat bender. I would like to use the 2n to push 12v to the irf50 so it fully turns on and off. I cant krf530 this to work.
I am thinking the problem arises because I am sinking the negative side of the leds through the transistor instead of putting power out of the transistor should I be using a p chanel transistor to feed the mosfet its 12v to turn on? Or is irr530 just not working because I am using the same 12v supply for both mosfet and transistor. Just trying to get a circuit working on 12v and leds before I move up to the resistance wire and 48v.
Wawa Shannon Member Posts: The easiest way is a logic N-channel mosfet, and switch the low side of the load.
Just use a ohm resistor between Arduino port and gate, and kohm from gate to ground. High side switching with a P-channel mosfet is another option, iirf530 more complicated.
More parts and slower switching. Can post a schematic if you want. TomGeorge Design and Repair of industrial control systems. Hi, Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png or pdf? Everything runs on krf530, let the smoke out, it stops running Irf350 posted this circuit more than once — Go To Reply 14 For The Latest Version It’s not optimized for yeah, you know, well every damn thingso it offends irt530 ol’ Mr.
What you’re attempting should correspond. Drive-by” that’s somebody else. As usual, Mr George demands every little bit documented and explained by the books theories to understand whats going on.
I will try to post what I did later when I get time but that is pretty much how I i wired it anders except i left out the 22k resistor. It just kept the lights ir5f30 no matter what.
Also I assume both the mosfet and transistor here are both n type? Thanks Pancake plus karma I got it to work I think I confused gain drain and source on the mosfst like a newb.
IRF530, SiHF530 product information
I did order some ttl level mosfets from sparkfun they had the lowest price by far even accounting ebay unless you buy a 10 pack from china and wait. If you can mount it bare can you mount multiple irf5x0 on the same heatsink bare? Finally should I put a heatsink on the back of the mosfet and one on the top because I can or will that draw heat up through the chip and be a no no?
Well I looked at the data sheet and basically it doesn’t say anything about the tab or hell ir530 didnt know to call it a tab because it doesn’t label it as that etc etc. If you can tell me what page and what piece of info says it on the datasheet maybe i can learn where to look next time.
You realise the logic mosfet you’re getting does not need a driver transistor. And that the posted circuit inverts change your code. And is “on” when the Arduino is off, and could be “on” during bootup.
And that 22k needs to be 1k to lower switching losses. Wawa on Apr 08, ,
