I think I have a pretty good grasp of low vs high side switching with MOSFETs and their gate drive requirements. My question is how does this work with logic level MOSFETs? Since they require a 5V logic level input, does it matter if they are used in low/high side configurations?
I have a circuit and it would be very convenient if I could use a single logic level MOSFET, but have it work in either low side or high side (the mode would be selected via jumpers).
This is for automotive use for low speed (on/off only) switching of low current loads like lights or small motors. Since automobile circuits are split between providing power (high side) or a ground (low side) to a device, I would like to have a single circuit operate with both using only a single MOSFET.
