Figure 24. High-Power Bus-Powered Function
USB POWER-DISTRIBUTION REQUIREMENTS
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 μF)
Functions must:
– Limit inrush currents
– Power up at <100 mA
The feature set of the TPS2062 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 25).
