I just need to switch on and off small DC motor. At 10 volt it is 4mohm and the fet can take 45 amp, but at 4. I seem to have missed your reply at first since I did not subscribe to your posts fast enough apparently: Using the transistor to drive the gate with higher voltage solved the problem. Or am I overlooking datasheef The circuit should be robust enough to support the load during a few minutes. I will try it again after soldering it instead of using a breadboard.

So no R1 and T1 from your diagram link? Sometimes a MCU seems to be driving a mosfet correctly, but only a careful measurement will show the mosfet is not getting fully turned on, overheating and wasting power.

This is for direct transfer so it is already mirrorred the right way. And a step up boost converter to supply the 5. I have a hard time believing it would work properly for reasons I explained earlier, but if you say it works for you… great. Like the diagram at the top of the page here. 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. Was that the same as for the mosfet?

At 5V volt on the gate, the IRF will pass something around 4. I have done like you said. Looking at the curve, at a irg9622 to source voltage of 5V the IRF is hardly turned on. I am not sure if there is an easier way to do it. It contains an opto-isolator and does all the gate driving.

I am getting almost 7V at the gate so no issues. The datasheet indicates max Vgs 4V but the datashret shows that at 5V the mosfet can deliver current way above my requirement.

I will use Arduino to dim the power acording to inputs from handlebar. Sorry no T2 and R1. It seems mosfet get burned every time. 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. If bought per 20 it is 26 eurocts a piece. Another thing to beware of in datasheets is Vthresh threshhold voltage. It is not expensive: Well what an amazing article.

Twitter Facebook Email Google. Fill in your details below or click an icon to log in: 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. You will find the print design here. Would be interested to hear how the FET holds out on 8 Amps.


Is there any logic mosfet capable to drive 25 Amperes? Also the and will be more efficient with this circuit. I was not aware of those. This site uses Akismet to reduce spam. Very good article, thanks for talking about a subject often overlooked by many.

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. Backyard dztasheet design Satasheet Arcana and RiderX. For the IRF it is even worse. Is it for audio?

This actually is used for heatedbed in datawheet printers up to A. Setting a temperature to a comfortable level arduino switches the mosfet on for sec followed by a 50sec off time. That 52 mOhms at 2. Notify me of new posts via email.
