6.3.4 Automatic Power Management

The TUSB542 deploys RX detect, LFPS signal detection and signal monitoring to implement an automatic power management scheme to provide active, U2/U3 and disconnect modes. The automatic power management is driven by an advanced state machine, which is implemented to manage the device such that the re-driver operates smoothly in the links.
