    Abstract: The purpose of the present invention is to protect the final transistor (PW) of a power actuator from short circuits and overloads with a completely integrated circuitry solution which would not influence the output impedance of the actuator and would permit having a limitation current constant and independent of the value of the output terminal of the actuator.
    A power actuator in accordance with the present invention incorporates a circuit for limitation of the maximum current delivered by the power transistor (PW) which comprises:

    a network for detection of the current delivered by the power transistor (PW) which generates a first electrical signal proportional to said current,
    a reference network generating a reference electrical signal, and
    an operational amplifier (3) which compares the first electrical signal with the reference electrical signal and which tends to inhibit the power transistor if the current delivered exceeds a certain threshold value and whose output terminal is coupled to the reference network in such a manner that the reference electrical signal depends on the voltage present at the amplifier output.
