This circuit can be used with 5 to 15 V sources and the zener diode must be chosen according to the trip voltage of the protector. The circuit blows the fuse when the voltage exceeds the zener value.
This circuit, which has a power of a few tens of microwatts, is suggested by Maxim. The circuit has a...
