I need a component/ set of components that totally cutoff the current if the voltage goes over 11.6 volts. Any ideas?

goodpickles said:Ok this is what I want to do with it. It is to protect a lead acid battery from being discharged below it's threshold point of 11.8 volts. Once the voltage drops below 11.8 it sends voltage to the rest of my circuit. Am am thinking of using 2 zener diodes connceted in series. (3.3, and 8.2 volts makes 11.5 volts which is close enough.
Styx said:dont you want an undervoltage detection circuit?
Use a comparator with a fixed reference
goodpickles said:Yes an undervoltage protector would be a much better name. that specific that I will be hooking up will be a 555 timer that makes a buzzer chirp every five minutes.
