PRODUCTION DATA.
Many adaptors that include USB PD must consume low quiescent power to meet regulatory requirements (that is, “Green,” Energy Star, or such). The device supports the sleep mode to minimize power consumption when the receptacle or plug is unattached. The device enters sleep mode when there is no valid plug termination attached; a valid plug termination is defined as one of: sink, Audio accessory, or Debug accessory. If an active cable is attached but its far-end is left unconnected or “dangling,” then the device also enters sleep mode. It exits the sleep mode whenever the plug status changes, that could be a dangling cable being removed or a sink being connected.
