The bus wake-up, often called remote wake-up, changes the operation mode from Sleep mode to Stand-By mode.
A falling edge on the LIN bus, followed by a dominate bus signal t > t
change to Stand-By mode becomes active with the following rising edge on the LIN bus. The TLE7259G remains
in Sleep mode until it detects a change from dominate to recessive on the LIN bus (see
In Stand-By mode the TxD pin indicates the source of the wake-up event. A weak pull-down on the pin TxD
indicates a bus wake-up event (see
event. A logical “Low” on the RxD pin reports a local or bus wake-up event, a logical “High“ signal on RxD indicates
a power-up event.
