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.
