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 understand. I have no ideia of what to do.
:(
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 read the value of Vload directly from the motor, then will be easier say if I need increase duty...
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 circuit works fine but I noticed that it wasn't so efficient. Now I am trying to use the IRF9640 with...
