Next to Shutdown Mode, the Disconnect mode is the lowest power state of the TUSB1002A. The TUSB1002A enters this mode when exiting Shutdown mode. In this state, the TUSB1002A periodically checks for far-end receiver termination on both SSTX1 and SSTX2. After detection of the far-end receiver’s termination on both ports, the TUSB1002A transitions to a fully active mode called U0 mode.
