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

IRLN – Infineon Technologies

If the steppermotor does not draw too much, think about an ULN I noticed that the range is very low. The only caveat using those AO parts, is their size: Also easier if you need to do high side switching. This site uses cookies.

The battery is ok and gives a steady 4 volts. I just need to switch on and off small DC motor.

That just will make your circuit much easier and save you a transistor and resistor. With regard to datasheey and 5V input, I presume you mean supply voltage. It already switches on at much lower voltages, albeit not completely, but the optimal voltage is around Volt.

At 10 volt it is 4mohm and the fet can take 45 amp, but at 4. Datashet in reality you dont need that formula as it mainly has to do with the range wherein the FET DrainSource acts as a pure resistor. Im actualy pondering the same question as Legolas. As there is an LED in the source to ground i presume ddatasheet, there is already a voltage drop, keeping the source above ground. If bought per 20 it is 26 eurocts a piece.

How we connect irf mosfethere the problem is …. The STP3NA I do not know very well and I couldnt quickly find a readable datasheet, but though it doesnt seem to be a Logic level FET, from what I could ratasheet, it should open enough around 3 volt already… but if you have a better datasheet, please check that.

I will try source a IRL That indeed is odd and I start to wonder if it is the IRL that is shutting down or something else. You need a logic fet for that such as the IRL series. The input capacitance is best chosen as low as possible. Perhaps one of the wires is corrupt. Another thing to beware lrl520n in datasheets is Vthresh threshhold voltage.

Notify me of new comments via email. Glad to be able to contribute! Well, you would need to put an inverter before the circuit i provided, either by a logical gate or with yet another transistor. The standard mosfet IRF series etc is designed to run from 10V. Should you however be irl520j with a FET like the IRF that really needs a high voltage to switch efficiently then use the following circuit: How can I find the current in the LED?


This is not the gate voltage to turn the device on, its the gate voltage at which it switches fully off less than a few uA of current, typically. This site uses Akismet to reduce spam.

What type of step up converter are you using? Thanks Adriaan, Though technically it is a voltage divider, that is not really the function of it.

Normally the impedance of a FET is high enough to not lose any signal over that resistor. OK I try again: The IRL is a logic level FET and putting 5 Volt on the gate should be enough to open it up, albeit that it has a drain source resistance of less than one ohm, though that depends a bit on the current and the temperature. Thanks — You are correct.

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

Thank you for this very good explanation. Great, that is good to know.

Excellent post, was very illuminating! You are limited to a current of about mA. The IRF is a better choice: Here is the curve for the IRL Well what an amazing article.

Use a baseresistor of say Ohm.
