It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. Thanks for pointing out that series. Well, you would need to put an inverter before the circuit i orf530a, either by a logical gate or with yet another transistor.

I am not sure what voltage you need but you may try this one a 30n If you come up with an idea I would be happy to hear it. Satasheet site uses Akismet to reduce spam. It shows the same behaviour when I use 3. I think that is not normal. A logic level mosfet means that it is designed to turn on fully from the logic level of adtasheet microprocessor. I noticed that the range is very low.

Great, that is good to know. 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. More and more cheap Mosfets.
According to your post and the datasheet, the IRLN should have no problem supplying the current at this voltage, right? Thanks, perhaps we are just discussing terminology here.
The relatively cheap BUZ11 is also an option. Thank you irf530w this very good explanation. That just will make your circuit much easier and save you a transistor and resistor.
You will find the print design here. You may also consider the IRLZ My hairs are starting to turn gray: Is it for audio? For a mA current you then need a seriesresistor of 33 Irf5330a. 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.
Perhaps it is a lose wire or something. It is not expensive: Then you can find the current in the datasheet? It is irf530z a true logic level mosfet, it needs some 10 volts. Glad to be able to contribute!

Thanks for your contribution. The question is the one joe provided a solution to in an earlier question, except just as you pointed out, his solution doesnt work because the emitter voltage will be close to 12V and the base voltage from the arduino will be 5V so the transistor will close.
Notify me of new comments via email. I am actually using it with octocoupler connected to 12V. Also easier if you need to do datasheer side switching. An attiny85 could do that as well. 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. Im actualy pondering the same question as Legolas.
