APPLICATION INFORMATION
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.
Bus-Powered Hubs must:
–
Enable/disable power to downstream ports
–
Power up at <100 mA
–
Limit inrush current (<44
and 10
μ
F)
Functions must:
–
Limit inrush currents
–
Power up at <100 mA
The feature set of the TPS2048 and TPS2058 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-power hubs, as well as the input
ports for bus-power functions (see Figure 32).
