... The TLE7269G contains 2 separate LIN transceivers, which are able to operate in two independent LIN networks with two different data transmission rates. The operation mode of the TLE7269G is selected by the EN pin and the TxD1 pin. Selecting the operation mode applies to the whole device. Transceiver1 and transceiver2 are always ...

... Normal Slope Mode In Normal Slope mode data transmission rates kBauds are possible. Setting the EN pin to “High” starts the transition to Normal Operation mode. Depending on the signal on the TxD1 pin, the TLE7269G changes either into Normal Slope mode or Low Slope mode (see The mode change to Normal Slope mode is defined by the time specifies the delay time between the threshold, where the EN pin detects a “ ...

... Wake-Up Bus2 Off A Wake-Up event on the LIN bus1 or on the bus2 wakes up the TLE7269G and sets it to Stand-By mode. In applications where a Wake-Up via bus1 is required but a Wake-Up via bus2 is not wanted, the bus Wake-Up event on the BUS2 can be disabled. This is done by setting the W2O pin to “High”. During the mode change from Normal Operation mode to Sleep mode the TLE7269G checks for the status on the pin W2O. In case the W2O pin is “ ...
Page 14
... 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 ...
