  1. Closed: Re: How to use TLP250 with a P-channel Mosfet with source of 180V

    Totem pole works when I use the same VCC that is connect do the transistors.

    But doesn't work with another power supply(i tested with 24v).
    :(

    Hii Goldsmith, it really help me. I finally understand!!

    I am going to try this way, then I post to you what happen!

    tx!

    Don't worry, english isn't my native language too.

    But, where I did an outline, it should be a short circuit, shouldn't ?

    i read something about totem pole, but it wasn't enougth to I...

    Those are my drews.

    Goldsmith iam studying your drews.


    Well, am planning to use the IRF540.

    Well, thanks for explain about the time of switching of mosfet.
    If I use a float ground, I couldn't read the value of Volts with a PIC.

    how can I break the DC brush motor?

    How can I know the value of frequency that should I use? What is 'value of IG'(IG?)?



    If I use a P mosfet, I will can have the GND of the motor in common with the whole circuit. And I will can...

    I guess that the conventional books aren't enough. Well at least here in Brazil they aren't. The technology of today is more complex than the book says.

    Hi everybody!

    I am having problems to use a P-Channel mosfet. I've made a circuit using a N-Channel Mosfet(IRF640) and another CI to switching(Til113 with the signal coming from a PIC). The...
