    Dear friends,

    I want to drive the 24 V DC motor 3 A current rating normal and 40A on startup. The circuit is shown below. Please let me know is it good for the PWM for atmega164pa please? The MOSFET I am using have upto80A current rating and 2.5V threshold for gate. please suggets me the best circuit for this. Please also suggest me the exact value for the resistances for this circuit please.

    Hello,

    I moved your post from the thread.
    The thread belongs to somebody else.
    Now you have a thread of your own.

    Your circuit dos not show.

    Is this a variable speed, or variable speed capable, because it sounds like you are starting the motor full on at that initial current?
