7.4.4 Wake Up Events

The TLIN1124A-Q1 supports two methods for wake-up from sleep mode:

  • Wake-up over the LIN bus via the LIN wake-up receiver: 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.
  • For a local wake-up via the SLP pin, the SLP pin must be set low for t > tMODE_CHANGE for the device to wake-up and fully transition to normal mode within tNOMINT.
