<p>This low voltage-controlled, stand-by electronic circuit with delayed switch off, comprises a switching circuit (6) defining a stand-by input receiving a stand-by switching signal and an output, and a delay circuit (9) generating a delayed switch off signal. The switching circuit comprises a controlled current source (6) having two control inputs (7,8), one (7) whereof is connected to the stand-by input (11) for switching on the controlled current source upon receiving the stand-by switching signal and the other (8) of the inputs is connected to the delay circuit (9). The delay circuit (9) is also connected to the stand-by input (11) and receives therefrom the stand-by switching signal for generating the delayed switch off signal, so that the controlled current source is switched on upon receiving the stand-by switching signal and remains on in absence of the stand-by switching signal and of the delayed switch off signal, the controlled current source being switched off by the delayed switch off signal on the second control input (11).</p> |
