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?

Learn how your comment data is processed. Good luck with your project. It shows the same behaviour when I use 3. What kind of lamp is it?

The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement Thank you for your help. I will use Arduino to dim the power acording to inputs from handlebar. It start switching on at around 3V and it seems to be quite wide open at 4,5V.

Using MOSFETS with TTL levels (5 Volt and 3.3 Volt)

Well, you would need to put an inverter before the circuit i provided, either by a logical gate or with yet another transistor. Can i use this circuit with Arduino to drive 2 x 20W 1.


Thanks, perhaps we are just discussing terminology here. Normally the impedance of a Dstasheet is high enough to not lose any signal over that resistor. IRFZ44, and you want to switch somewhat higher voltages i. And as i understand when you put 5 volt on the gate, the output on the source i presume is only 5Volt.

The relatively cheap BUZ11 is also an option. Maybe you alreadymeasured it but just to make sure, when your problem aises, have you measured if there is still voltage on the gate or even voltage on your PSU?

The standard mosfet IRF series etc is designed to run from 10V. Keep an eye on the temperature though when you start using it with 8 amps. You need a logic fet for that such as the IRL series.

I am not sure where you are based but the IRL costs abt 60 cts where I am. At 5 Volt GS it can however only take some 4.

I have done like you said. It is not a true logic level mosfet, it needs some 10 volts. The transistor may burnt. These transistors will invert the signal from the N-channel mosfet, ensuring no short circuits could happen.

By continuing to use this website, you agree to their use. Try just to test without the converter, 3. As there is an LED in the source to ground i presumethere is already a voltage drop, keeping the source above ground. Use a baseresistor of say Ohm. Checking the datasheet is always a good suggestion.

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.

At 10 volt it is 4mohm and the fet can take 45 amp, but at 4. This site uses Akismet to reduce spam.

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 enough to make 10 amp no problem. Yes im using Arduino to control the circuit. To find out more, including how to control cookies, see here: I will try it again after soldering it instead of using a breadboard. I am not sure if there is an easier way to do lr042n. If bought per 20 it is 26 eurocts a piece.

The input capacitance is best chosen as low as possible. The dissipation then is 5x5x0. It is not expensive: However I advise you against building that yourself as they are rather cheap if you just buy them: The IRLN can take 36 amps.
