Good morning all.
I am learning how to use a toten pole circuit to drive a MOSFET. At this time, I can make it work like the image below:

The input signal is a PWM signal. On the image above, i am not sure but I guess it has 10% in duty cicle.
So, the problem is that the circuit is working in reverse.
With 10% of the PWM I have 90% of the current flowing on the FET.
I want to have 10% on the PWM and 10% of the current, 90% on PWM, 90% in current. That need to be direct proporcional.
I tried to use a PNP transistor but did not worked.
bye
