Hi guys I need to make a simple switch that turns OFF anytime the voltage is below 9v.
I was wondering if I took a mosfet to be the switch and put a 9v zener diode on the gate, would this circuit work well? In principle anytime the voltage is 9v zener brakes down and mosfet/switch would conduct. And if it goes below 9v the zener stops conducting and so does the mosfet right?
PS zener question, if a zener is rated at say 9v break down, will it conduct right at 9v and above? And when does it stop conducting 8.9v 8.8v? 8v?
My setup uses 10v and 8v, change between the two is fast. At 8v I need it to not conduct and at 10v circuit above needs to conduct. Would I then choose a 9v zener, right in between the 2 voltages?
