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.
