MOSFET Circuit Breaker
Cutting the power rapidly in the event of an overload implies monitoring the current through the load. This is usually done either by measuring the voltage difference across a series resistor, or by using a Hall-effect current sensor. This second solution is certainly appealing, but the cost of these sensors is still quite high, and they’re not all that easy to implement.
