Abstract

See full text

A switching circuit comprising a transistor (23) and a drive component both for controlling the transistor and also for limiting the power supply current (Ia) suppled to a load (22), the drive component being arranged both to receive a control voltage (VH) and also:

    when the control voltage (VH) is disconnection signal, to generate a drive voltage (Vp) that causes the transistor to occupy a non-conductive state;when the control voltage (VH) is a connection signal and the power supply current (Ia) cannot reach a predefined current threshold, to generate drive voltage (Vp) that causes the transistor to occupy saturated conditions; andwhen the control voltage (VH) is a connection signal and the power supply current (Ia) can reach a predefined current threshold, to generate a drive voltage (Vp) that causes the transistor to occupy linear conditions, such that the power supply current is regulated so that it does not exceed the predefined current threshold.
