Hi everyone,
I originally used an n-channel MOSFET with an Atmel doing PWM and it works great, however, I need the load to be on the other side of the MOSFET. Based on the way they work, I figured a P-Channel MOSFET will be perfect.
This is how I have it now:
**broken link removed**
However, using the P-channel MOSFET I can move it down:
**broken link removed**
My question, with the N-channel MOSFET, I fed the gate a positive voltage and it worked just as I wanted. However, with the P-channel, do I have to send the gate a negative voltage? As in, will the P-channel MOSFET be working a straight-through diode when the gate is not powered?
