USB POWER-DISTRIBUTION REQUIREMENTS
SLVS798F – JANUARY 2008 – REVISED NOVEMBER 2008 ........................................................................................................................................... www.ti.com
USB can be implemented in several ways regardless of the type of USB device being developed. Several
power-distribution features must be implemented.
SPHs must:
–
Current-limit downstream ports
–
Report overcurrent conditions
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 TPS2062A/66A meets each of these requirements. The integrated current-limiting and
overcurrent reporting is required by self-powered hubs. The logic-level enable and controlled rise times meet the
need of both input and output ports on bus-powered hubs and the input ports for bus-powered functions.
