Abstract:
A method can be used for managing a power supply voltage on an output power supply pin of a USB Type-C source device coupled to a USB Type-C receiver device via a USB Type-C cable. A first measurement of a first voltage on a channel configuration pin of the cable is performed when the receiver device is not powered and a second measurement of a second voltage on the channel configuration pin is performed when the receiver device is powered. A difference between the first and second voltages is calculated and the power supply voltage is modified as a function of a value of the difference.
