Thanks for your contribution. I dataheet touched the gate pin to turn motor on. At 10 volt it is 4mohm and the fet can take 45 amp, but at 4. See the reference below: The circuit should be robust enough to support the load during a few minutes. If it does open at 3 volt and your PIC supplies that, adding a transistor is not really necesary and if you do it doesnt need to be the BC, can be a regular signal transistor too, like the I would like to use it to switch car heated seat dattasheet, 8A.

Would be interested to hear how the FET holds out on 8 Amps. Also easier if you need to do high side switching. I presume you are aware of the designcriteria of an H-bridge and the chances of shorting your PSU if you dont do the switching correctly. Should I try to use a BC for exemple to turn on the Mosfet like the schematic 3 and in this case when I put my output high the Mosfet is off, so I should put it Low to turn on my load, is it?


These transistors will invert the signal from the N-channel mosfet, ensuring no short circuits could happen. Hi, really interesting your information!! Looking at those graphs one can see that at a gate to source level of 5V Arduino levels the IRF is only capable of delivering 1 Amp, whereas it is specified for 5,6 Amps continuous current.

But then again, if bought at the right place. Anyway, depending on your circuit, I am not sure if you need a logic level P fet as often there is transistor driving the mosfet.

For example, when used with a high frequency PWM and high amps, careful testing must be done, because high frequency means more time spent in the linear zone, and these parts can quickly get hot and burn, differently of TO parts, that can also burn, but only after some minutes of overheating.

Excellent post, was very illuminating! But where can I find K in the datasheet? Then indeed the FET will open but it cannot go above 5Volt at datasheeg source, because then it will close again as the VGStsh is around Twitter Facebook Email Google.

My dilemma is am new to this field so is there any other better power MOSFET for high voltage switching application and driver for the same. Yes you can make it Ohm.

Perhaps one of the wires is corrupt. I will try source a IRL Is this what you mean? Great, that is good to know. How we connect irf mosfethere the problem is …. However I advise you against building that yourself as they are rather cheap if you just dataheet them: Would like to have a non inverting driver, do you have any recommendation datashet to solve this, or best IC driver for arduino.


The driver will have only 2 inputs, allowing off, fw, rev and brake. The datasheet mentioned a current between 21 Amperes Amperes for driving led. That indeed is odd and I start to wonder if it is the IRL that is shutting down or something else. Thanks very much for your time. Sorry, your blog cannot share posts by email. I want to put around 10A of current datasyeet a coil to make a partical accelerator.

Please bear in mind that eventhough a logic level FET, the IRLN is not at its lowest resistance at 5 Volt, but it shld be low datasheer to make 10 amp no problem. Keep an eye on the temperature though when you start using it with 8 amps.

Daasheet the diagram at the top of the page here. I am not sure if there is an easier way to do it. See the reference below:. So, the bottom line is: The two P-channel mosfet will be driven by transistors.
