Abstract: An apparatus is for testing a device to be supplied with power via USB Power Delivery (USB-PD). The apparatus includes at least one USB Type-C connector configured to be connected to the device to be supplied with power to be tested, the at least one USB Type-C connector including a power supply terminal. Processing circuitry of the apparatus is configured to verify that a voltage at the power supply terminal is lower than a first threshold, verify a role of the device, generate requests representative of power supply configurations supported by the role of the device, and verify compatibility of the power supply configurations supported by the device with standardized power supply configurations.

Abstract: A first terminal receives a first DC voltage. A switch selectively couples the first terminal to a second terminal providing an output. A control circuit selectively actuates the switch in response to a comparison of the first DC voltage to a second DC voltage. A low-dropout (LDO) linear voltage regulator, connected between the first and third terminals, operates to provide the second DC voltage from the first DC voltage.

Abstract: Provided is a method implemented in a USB-C supply interface connected between a supply source and a USB-C connector coupled to a load. A comparison is performed between at least one signal representative of an operation of a voltage converter belonging to the interface and at least one threshold. A command module belonging to the interface emits an activation signal to control electrical isolation between the source and the converter. Isolation is implemented by a disconnection device connected between the source and the converter. The disconnection device irreversibly electrically isolates the converter from the source when the activation signal is emitted. The present description also relates to a USB-C supply interface configured to implement such a method.

Abstract: The present disclosure relates to a method for sanitization of a surface by emission of a plurality of sanitization wavelengths, and to a device for implementing the method. The method comprises emitting light using first LEDs configured to emit the sanitization wavelengths, receiving, by a circuit, a feedback signal from a light sensor indicating a light intensity received by the light sensor during the light emission, and controlling the first LEDs with the circuit based on the feedback signal.

Abstract: The present disclosure concerns a device comprising: a voltage converter supplying, from a first DC voltage, a second DC voltage on an output terminal of the converter having a current value determined by a third voltage on a control terminal of the converter; a circuit configured, when a set point value of the second voltage switches from a first to a second set point value smaller than the first value, to generate a ramp signal successively representative of the first value, of a plurality of decreasing intermediate values between the first and second values, and of the second value; and an amplifier supplying a first signal representative of a difference between the ramp signal and a signal representative of the current value of the second voltage, the third voltage being determined by the first signal.
