Hi all, I'm adding something on to a project I designed awhile ago, and I just want to double check something. I am adding an N-Channel MOSFET to an existing project of mine to allow for a greater load capacity. It will be on/off, but might involve PWM. At the moment I'm looking at the STP36NF06L, mainly because I've seen it used in a few examples and I can get it easily, but I am open to other easy to drive parts. The question is, if I'm adding this on the low side, as long as the high side is greater or equal to the gate voltage, am I ok? For now the MOSFET high side will be at 5V, same as Vdd, but in the future I might want it a bit higher to switch something else (say 12V). I believe I'm fine at 12V, but I want to make sure that having the high side at 5V and the gate voltage (coming from the PIC) at 5V won't cause something I haven't thought of. Thanks!
