Abstract

An electronic fuse system includes plural current paths, each operable to be coupled between a power source and a load, and each including a switching element and a current sensing resistor in series with the path such that the path passes current when the switching element is turned on and does not pass current when the switching element is turned off. A controller has two sense inputs and a control output. The control output is coupled to the switching elements in each of the plural current paths and is operable to turn them all on or off simultaneously responsive at least in part to the sense inputs. A summing resistor is connected across the two sense inputs, and coupling circuitry is operable to couple voltages appearing across the current sensing resistors to the summing resistor.
