The TPS2070 and TPS2071 provide a complete USB
hub power solution by incorporating four major
functions: current-limited power switches for four
ports, a 3.3-V 100-mA regulator, a 5-V regulator
controller for self-power, and a DP0 line control to
signal attach/detach of the hub.
These devices are designed to meet bus-powered
and self-powered hub requirements. These devices
are also designed for hybrid hub implementations and
allow for automatic switching from self-powered mode
to bus-powered mode if loss of self-power is
experienced (can be disabled by applying a logic high
to BP_DIS).
