USB POWER-DISTRIBUTION REQUIREMENTS
www.ti.com................................................................................................................................................ SLVS714A – FEBRUARY 2007 – REVISED MARCH 2009
Figure 26. High-Power Bus-Powered Function
USB can be implemented in several ways, and, regardless of the type of USB device being developed, several
power-distribution features must be implemented.
Hosts/SPHs must:
Current-limit downstream ports
Report overcurrent conditions on USB VBUS
BPHs must:
Enable/disable power to downstream ports
Power up at <100 mA
Limit inrush current (<44
and 10
F)
Functions must:
Limit inrush currents
Power up at <100 mA
The feature set of the TPS206x-1 allows them to meet each of these requirements. The integrated
current-limiting and overcurrent reporting is required by hosts and self-powered hubs. The logic-level enable and
controlled rise times meet the need of both input and output ports on bus-powered hubs, as well as the input
ports for bus-powered functions (see Figure 27).
