摘要： A system may include a power supply configurable to generate any of a plurality of output voltages on a power supply output node. The system also may include a voltage auto-detection power distribution (PD) controller coupled to the power supply. The voltage auto-detection PD controller is configured to monitor an input signal for detection of presence of a device coupled to the system via a cable and assert combinations of a plurality of control signals. For each combination of control signals, the voltage auto-detection PD controller measures a value of an output voltage from the power supply, stores the measured value, and generates a plurality of packets for transmission to the device. Each packet contains a parameter indicative of a measured output voltage.

摘要： An electronic system includes a computer and a power adapter. The computer includes an embedded controller (EC) coupled to a computer power delivery (PD) controller. The power adapter includes a power adapter PD controller connected to a slave device and is configured to communicate with the computer over a communication link. The computer PD controller is configured to receive a command from the EC and, to transmit a universal serial bus (USB) vendor defined message (VDM) header and one or more vendor defined objects (VDOs) including the information of the payload of the transmit command. The power adapter PD controller responds to the one or more VDOs either by changing an output signal to the slave device connected to the power adapter PD controller, reports a state of a general purpose input/output (GPIO) pin of the power adapter PD controller, or changes the state of the GPIO pin.
