Abstract: An electronic monitoring circuit for detecting a variation in the power or current absorbed by an electronic circuit under test is disclosed. The circuit includes an input terminal adapted to receive a pulse-width modulation control signal, a resistor having a first terminal connected to the input terminal, and a capacitor having a first terminal connected to a second terminal of the resistor. The output terminal is adapted to generate an output signal as a function of the value of the voltage drop at the ends of the capacitor, said output signal being representative of a variation of the pulse width of the pulse-width modulation control signal. The variation of the pulse width is a function of the power or current absorbed by the electronic circuit under test.

Abstract: A power supply system includes a power supply circuit, a sensor of the current flowing through a terminal of the power supply circuit and a protection circuit. The protection circuit includes a differentiator adapted to measure a slope of a current measurement signal and comprises a driving stage. The power supply circuit is configured to receive a disconnection signal and, alternatively, to electrically connect the internal components thereof to its terminal or electrically disconnect the internal components thereof from its terminal, as a function of the value of the disconnection signal.
