At 8A it is not even breaking a sweat. But then again, if bought at the right place. Sorry, your blog cannot share posts by email. For a mA current you then need a seriesresistor of 33 Ohm.

You need a logic fet for that such as the IRL series. Checking the datasheet is always a good suggestion. Thank you for this very good explanation. Setting a temperature to a comfortable level arduino switches the mosfet on for sec followed by a 50sec off time. Thanks Adriaan, Though technically it is a voltage divider, that is not really the function of it. 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.

Great, that is good to know. Like irf622 diagram at the top of the page here. That is not surprising. I just touched the gate pin to turn motor on. 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?

It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. To find out more, including how to control cookies, see here: That just will ir9622 your circuit much easier and save you a transistor and resistor. 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.

Perhaps it is a lose wire or something. Somehow Logic P channel mosfetsarent as plentiful. If you come up with an idea I would be happy to hear it. It is not a true logic level mosfet, it needs some 10 volts.

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

So, mistakes during development can be fatal. Try just to test without the irf962, 3. 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. I am not sure where you are based but the IRL costs abt 60 cts where I am. Thank you for your answer.

Datashete transistor may burnt. I would like to use it to switch car heated seat 12V, 8A. 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.

Do you have any idea why is the mosfet not working properly and letting the 12v works on the led strip?

Would like to have a non inverting driver, do you have any recommendation how to solve this, or best IC driver for arduino. Much better to use a cheap Darlington transistor then.
