AT43312A
1255G–USB–05/06
Bus Powered Mode
In the bus powered mode, all the power for the hub itself as well as the downstream
ports is supplied by the root hub or upstream hub through the USB. Only 100 mA is
available for each of the hub’s downstream devices and therefore only low power
devices are supported.
The power switch and overcurrent protection works exactly like the self-powered mode,
except that the allowable switch resistance is higher: 700 m
or less under the worst
case condition.
The diagrams of Figure 2 and Figure 3 show examples of the power supply and man-
agement connections for a typical AT43312A port in the self-powered mode and bus
powered mode.
