It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. What type of step up converter are you using? Rds 38mOhm with a Vgs of 3. You could consider the FQP27P They are good switches,but you dont want to use them as resistors. Sorry no Datasbeet and R1.

You may want to read up here https: Whats about this, I have check in the datasheet and seems to work very well at TTL levels even with a lot of Amps.

Great, that is good to know.

So no R1 and T1 from your diagram link? Using the transistor to drive the gate with higher voltage solved the problem. I can imagine that a SOT23 indeed can only take a current the size of 7 amps if there hardly is any dissipation read low RDSon.

Then you can find the current in the datasheet? Glad to be able to contribute! Fill jrf9622 your details below or click an icon to log in: I am not sure what voltage you need but you may try this one a 30n Yes im using Arduino to control the circuit.


The IRF can obviously take 4 amps, but sadly it expects a higher voltage on its gate than the most microcontrollers can satasheet i presume you will use a microcontroller.

Well, you would need to put an inverter before the circuit i provided, either by a logical gate or with yet another transistor.

I want to put around datasheft of current trough a coil to make a partical accelerator. The transistor may burnt. If the steppermotor does not draw too much, think about an ULN Though that seems like the FET is suitable for an Arduino, I do not think it is an optimal combination.

It is not a true logic level mosfet, it needs some 10 volts. But where can I find K in the datasheet? I am getting almost 7V at the gate so no issues. The simplest circuit is just a 12 V regulator but that is very inefficient.

I am actually using it with octocoupler connected to 12V. Another thing to beware of in datasheets is Vthresh threshhold voltage. That means you have to have a 12 Volt driver as in this circuit: You will find the print design here.


What kind of lamp is it? At 8A it is not even breaking a sweat. I am not sure if there is an easier way to do it. This is for direct transfer so it is already mirrorred the right way. Notify me of new comments via email.

Was that the same as for the mosfet? IRFZ44, and you want to switch somewhat higher voltages i. I am using this converter: For a mA irf962 you then need a seriesresistor of 33 Ohm. The 20 Volt you probably saw in the datasheet, but that is the max voltage on the gate. You are limited to a current of about mA.

If it is not dataxheet, the gate will not get any voltage from the 12 V power source. 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.

The battery is ok and gives a steady 4 volts. If it would be just a wire i.
