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).

Abstract: A protection circuit (P) for protecting a load (L) against overcurrents, and including input terminals (IN1,IN2) to be coupled to first and second power supply terminals of a power supply, output terminals (OUT1, OUT2) to be coupled to respective terminals of said load (L), further includes an enable output terminal (EOUT) for provision of an enable signal to said enable input terminal (ENin) of said load (L) an RC circuit (R1,C1), a capacitor (C1) of which is coupled between said first (OUT1) and second (OUT2) output terminals, a resistor (R1) of which is coupled between said first input terminal (IN1) and said first output terminal (OUT1), a switch (SW) coupled in parallel across said resistor (R1), and being controlled by said enable signal received from an enable control block (ECB), for sensing the current through said resistor (R1) via sensing input terminals coupled across said resistor (R1), and for generating said enable signal upon detecting that said current drops below a predetermined thresho
