Sleep Mode

Sleep Mode is the power saving mode for the TLIN2024A-Q1. Even with extremely low current consumption in this mode, the LIN channel can still wake-up from LIN bus through a wake-up signal or if EN is set high for > tMODE_CHANGE. The LIN bus is filtered to prevent false wake-up events. The wake-up events must be active for the respective time periods (tLINBUS).

The sleep mode is entered by setting EN low for longer than tMODE_CHANGE.

While the device is in sleep mode, the following conditions exist.

  • The LIN bus driver is disabled and the internal LIN bus termination is switched off (to minimize power loss if LIN is short circuited to ground). However, the weak current pull-up is active to prevent false wake-up events in case an external connection to the LIN bus is lost.
  • The normal receiver is disabled.
  • EN input and LIN wake-up receiver are active.
