Abstract

A method includes determining a first voltage that is in a high-side path of a circuit, the path including a high-side switch connected between a first potential connection of the circuit and a first connection of a load of the circuit; determining a second voltage that is in a low-side path of the circuit, the path including a low-side switch connected between a second potential connection of the circuit and a second connection of the load; responsive to a determination that one of the voltages exceeds a threshold for at least a duration of a predefined time interval, checking whether the other voltage currently exceeds the threshold; and determining that there is a short circuit across the load or in whichever of the paths has the voltage that exceeded the threshold for the duration, respectively, if the result of the check is positive or negative.
