The bus Wake-Up event, often called remote Wake-Up, changes the operation mode from Sleep mode to Stand-
By mode. The TLE7269G wakes-up via a bus Wake-Up event on either the pin BUS1 or BUS2. The bus Wake-
Up behavior is identical on both pins. A falling edge on the LIN bus, followed by a dominant bus signal t > t
results in a bus Wake-Up event. The mode change to Stand-By mode becomes active with the following rising
edge on the LIN bus. The TLE7269G remains in Sleep mode until it detects a change from dominant to recessive
on the LIN bus (see
In Stand-By mode the TxD1 pin indicates the source of the Wake-Up event, the TxD2 pin remains inactive. A weak
pull-down on the pin TxD1 indicates a bus Wake-Up event (see
Wake-Up event occurred or the power-up event. A “Low” signal on the RxD1 pin reports a local or bus Wake-Up
event, a logical “High“ signal on RxD1 indicates a power-up event. A “Low” signal on the RxD2 pin indicates a
Wake-Up event on the pin BUS2.
