about fet transistor dose my circuit right?

Hello.
I'm planning to turn on IRF1405 using IRFz44n. cause of base voltage.
At 25V, there is a motor that couldn't show in circuit.
It is just 2 parallel circuit but my project is 50 parallel circuit.
Also, 12V adaptor is 1.5A. so at IRFz44 it cause almost 30 ma so it's okay to drive 5V.

So, does it all right to drive it?

From your description its not clear what you are trying to accomplish. The circuit you attached seems overly complicated but I can't be sure without knowing the goal / restrictions.

If you cannot draw a schematic the minimum is:

The ultimate goal.

Where the signal starts (arduino etc)
what will be driving the fet's you show
what is your load

Are you trying to make an 'H' bridge - ie something to drive a dc motor in either direction?

If so google it.

The circuit has several misconceptions.

  1. why need a MOSFET to drive a similar MOSFET? Doesn't make sense, you still have to
    drive the first MOSFET which is exactly the same problem. Both your devices are not logic
    level.

  2. You don't use source-follower configuration for switching (your IRFZ44N's are source-followers)
    You use common-source configuration always, which in your circuit would require p-channel MOSFETs
    in place of the IRFZ44N's - but this is a moot point, the circuit needs redesigning.

  3. You have no load - you basically turn on the IRF1405's and they short the 25V supply to ground
    and explode. This is obviously not what you mean to do!

At 25V, there is a motor that couldn't show in circuit

yes you could, you chose not to.

  1. Has to be said over and over on these forums - you cannot drive a non-logic-level MOSFET direct
    from an Arduino. You either use a logic-level MOSFET (which can be driven directly with nothing
    else but some resistors), or you use a MOSFET gate driver chip to drive the MOSFET. There are literally
    thousands of gate driver chips available, all are specifically designed for the purpose, and then drive
    non logic-level MOSFETs and take logic signals as inputs.

The gate driver chip approach is capable of much higher PWM frequencies as they do rapid gate charging
and discharging which an Arduino pin cannot do.

I suggest you explain what you are trying to do with your circuit.
