As a result open load and over load including over temperature can be differentiated in ON-state.
Consideration must be taken in the selection of the sense resistor in order to distinguish nominal currents from the
overload/short circuit fault state. A potential of 5 V at the sense pin can be achieved with a big sense resistor even
with currents being much smaller than the current limitation.
