    Abstract: PROBLEM TO BE SOLVED: To provide a driving circuit for an electric load, which detects a state of a load connected erroneously.
    SOLUTION: An electronic circuit (100) is disclosed, having: a node (EX) connectable to a load (LD) to be driven; and a power device (PD) with a first terminal connected to the node, to be switched between activation and deactivation. The circuit further has: a current generator (I) having an output connected to the node, which can be switched to an enabled state, at least when the power device is deactivated; and a comparator (CP) for comparing a voltage of the node (V(EX)) with a reference voltage (V(REF)). The comparator is configured to obtain comparison results (RESETN), from which a distinct condition of electric connection of the load to the node is detected.
