1. A system for controlling power supply to a load from a power supply line, the system comprising:
a first circuit comprising a first path for supplying power to the load and a first switching mechanism for controlling the supply of power through the first path;
at least one second circuit comprising a second path for supplying power to the load and a second switching mechanism for controlling the supply of power through the second path,
wherein the first circuit and the at least one second circuit are connected in parallel between a load connection node (ND2) and a power supply line node (ND1),
wherein each of the first and second switching mechanisms includes a first set of N1 transistors connected in parallel between the power supply line node (ND1) and a first internal node (NDint1a, NDint1b), with N1>1, and a second set of N2 transistors connected in parallel between the load connection node (ND2) and a second internal node (NDint2a, NDint2b), wherein the first internal node and the second internal node are connected in series to each other, and
wherein the first internal node and the second internal node are connected to each other through a current detection device;
a control module configured to output control signals to control operations of the first circuit and the at least one second circuit so as to independently switch on or off each of the first and second paths; and
a monitoring module configured to monitor one or more physical quantity parameters of the first and second paths,
wherein the monitoring module is configured to detect, based on a comparison, deviations of values of the monitored one or more physical quantity parameters from respective reference values, so as to check a consistency between the first and second paths.
