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.

Power supply system with protection against current variations

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.

Electronic monitoring circuit for detecting the variation in the power or current absorbed by at least one electronic circuit under test and electronic system for testing the operation of the at least one electronic circuit
