Completely disconnect the U2p internal PD chip without affecting the

communication between the PD charging head and the PD phone

This mode is the "through mode" that you are used to by calling, that is, it does not affect any

communication between the pd charger and the powered device.
At this point, the charger and the PD power device are serially connected to U2p, and U2p is

compared to a common multimeter.
U2p can brighten and monitor the current and voltage status on the power line on any interface
