9.4.4 Wake-Up Events

There are three ways to wake-up the TLIN1021-Q1 from sleep mode:

  • Remote wake-up initiated by the falling edge of a recessive-to-dominant state transition on the LIN bus where the dominant state is be held than tLINBUS filter time. After the tLINBUS filter time has been met a rising edge on the LIN bus going from dominant-to-recessive initiates a remote wake-up event. The pattern and tLINBUS filter time used for the LIN wake-up prevents noise and bus stuck dominant faults from causing false wake requests.
  • A local wake-up event due to the EN pin being set high for t > tMODE_CHANGE.
  • A local wake-up event due to a change in voltage level on the WAKE pin for t > tWAKE
