Please help me out. Datzsheet will try source a IRL Would like to have a non inverting driver, do you have any recommendation how to solve this, or best IC driver for arduino. I even used feedback protective diode with motor. I just touched the gate pin to turn motor on. You are limited to a current of about mA. Thanks very much for your time.

Keep an eye on the temperature though when you start using it with 8 amps. Notify me of new comments via email. According to your post and the datasheet, the IRLN should have no problem supplying the current at this voltage, right? I will use Arduino to dim the power acording to inputs from handlebar.

The STP3NA I do not know very well and I couldnt quickly find a readable datasheet, but though it orf530a seem to be a Logic level FET, from what I could see, it should open enough around igf530a volt already… but if you have a better datasheet, please check that.

The only conditions are it should have high switching speed so low rds on and high break down voltage. Good luck with your project. Backyard controller design Eric’s Arcana and RiderX.


My hairs are starting to turn gray: Excellent post, was very illuminating! In general you want a MOSFET that has a low Rdson and switches fast at the available triggervoltage 5volt with ttl and ofcourse can take the voltage and current it will be exposed to. Though that seems like the FET is suitable for an Arduino, I do not think it is an optimal combination. By continuing to use this website, you agree to their use.

You could consider the FQP27P The gate source resistor is purely to make a predefined state and to avoid the entrance to float I do not know the PIC18F that well, but what is important is the Output voltage it has on its pins. Thanks — You are correct.

I am not sure what voltage you need but you may try this one a 30n So no R1 and T1 from your diagram link? If you come ir5f30a with an idea I would be happy to hear it. That indeed is odd and I start to wonder if it is the IRL that is shutting down or something else. The dissipation then is 5x5x0. It contains an opto-isolator and does all the gate driving. Then indeed the FET will open but it cannot go above 5Volt at the source, because then it will close again as the VGStsh is around This is not the gate voltage to turn irf5330a device on, its the gate voltage at which it switches fully irt530a less than a few uA of current, typically.


It start switching on at around 3V and it seems to be quite wide open at 4,5V. Switching speed indeed is important.

How can I find the current in the LED? Sadly though it can only dissipate some 80 Watts There is the MTB60N05HD L that does 60 amps 50 Volt and Amps beware of the somewhat high input capacutance, bu thta does not need to be a huge problem in simple switching also you may consider browsing through this guide. The IRF is a better choice: Try just to test without the converter, 3.

And as i understand when you put 5 volt on the gate, the output on the source i presume is only 5Volt.

Thanks in advance, Ruben. The only caveat using those AO parts, is their size: But where can I find K in the datasheet? Or am I datashewt something? Apologies foe my late reply. Thanks for pointing out that series. IRFZ44, and you want to switch somewhat higher voltages i.

Somehow Logic P channel mosfetsarent as plentiful. See the reference below:. Or for a power rectifier?

I have chosen to put one in just to be sure.
