In Stand-By mode the RxD1 pin signals the low power supply condition with a “High” signal. A logical “High” on
the EN pin changes the operation mode back to Normal Operation mode.
In case the supply voltage
disables the output and receiver stages. This feature secures the communication on the LIN bus. If the power

If the TxD1 or TxD2 signal is dominant for a time t > t
of the LIN signal to the bus and disables both, the output stage 1 and the output stage 2. This is realized to prevent
the bus from being blocked by a permanent “Low” signal on the TxD1 or TxD2 pin, caused by an error on the
external microcontroller (see
The transmission is released again, after a rising edge at TxD1 or TxD2 has been detected.
