Notes 1.
Ports available but inactive or unplugged do not add to the power consumption.
2.
The power consumption depends on the number of ports available and actively operating.
3.
If the

PD720114 is locally powered and the upstream facing port is unplugged,
μ
PD720114 goes into
suspend state and downstream facing port V
BUS
goes down.
