Abstract: A protection circuit (P) for protecting a load (L) against overcurrents, and including input terminals (IN1,IN2) coupled to first and second power supply terminals of a power supply, output terminals (OUT1, OUT2) coupled to respective terminals of said load (L) , a first active device (T2) having a control electrode and a conductive controlled path coupled between the first input terminal (IN1) and the first output terminal (OUT1), a charging circuit (I,C1,R4) for turning on the active device upon coupling the power supply to the input terminals (IN1,IN2), a current limiting circuit (R2,T1) for limiting the current through the conductive path of said active device (T2) at a current limit value (Ilimit), and a fuse (F1) coupled in series via the first input terminal with the conductive controlled path of the active device (T2).
