After outputting 5V voltage on the Source side, it communicates with the Type-C controller IC in the dedicated cable to acquire cable information. After communicating with the cable on the Source side, the Source side transmits its own power profile information to the Sink side. (Source Capability) The Sink side requests an appropriate voltage from the power profile to the Source side. (Request) In response to the Sink side voltage request, if the Source side is able to deal with it, notifies the Sink side that it acknowledged. (Accept) The Source side outputs the requested voltage to the VBUS pin. After outputting the required voltage, the Source side notifies the Sink side that the requested voltage has been output. (PS_RDY) After confirming the requested voltage, the Sink side turns on the FET switch on the VBUS line. ・20V negotiation waveform 20V VBUS output From Source side 20V 5V VBUS tChg tChg E-marked Cable Detect 0V Plug insert VBUS Source Capability Request PS_RDY CC1 CC2 Accept Figure5.
