12. Power consumption
Table 118
shows the power consumption when two ports are active, that is, the
SEL2PORTS pin is connected to V
DD
.
[1]
When one or two full-speed or low-speed power devices are connected, the power consumption is comparable with the power
consumption when no high-speed devices are connected (there is a difference of approximately 1 mA).
Table 119
shows the power consumption when four ports are active, that is, the
SEL2PORTS pin is connected to ground.
