Abstract: In described examples, a method includes receiving, by a power delivery (PD) controller, a first sensed voltage, while the PD controller is producing a first control signal and in response to determining that the first sensed voltage passes a threshold voltage, starting, by the PD controller, a timer, where the threshold voltage is a first threshold, a second threshold, or a third threshold. The method also includes during a time period of the timer, producing, by the PD controller, the first control signal and during the time period of the timer, receiving, by the PD controller, a second sensed voltage. Additionally, the method includes after expiration of the timer, producing, by the PD controller, a second control signal based on the second sensed voltage.

Abstract: A multi-port charging system includes a controller having a power input terminal coupled to a DC power output of a converter, multiple power output terminals coupled to the power input terminal, and a communications input terminal. The system includes multiple charger ports, the respective charger ports having a charging power line coupled to a respective one of the power output terminals, and a communications line coupled to the communications input terminal. The controller is configured to control the state of the control output terminal to set a voltage of the DC power output according to a selected highest common compatible voltage of one or more sink devices coupled to one or more respective ones of the charger ports.

Abstract: In described examples, a source circuit can have an input and an output. The input can be adapted to be coupled to an input voltage source configured to provide an input voltage. The source circuit can be configured to output power at an output based on a power delivery mode. The source circuit can include a timer and power delivery (PD) controller. The PD controller can be configured to control the power delivery mode responsive to the input voltage and the timer. The PD controller can be further configured to set a respective power delivery mode and initiate the timer for a timer duration based on the input voltage relative to an input voltage threshold. The PD controller can be further configured to continue operating in the respective power delivery mode for the timer duration.
