The TLE 7263E offers a transceiver, which is compatible to ISO 9141 and LIN
specification 2.0. For fail safe reasons the transceiver already has a pull-up resistor of
30 k implemented. In order to achieve the required timing for the dominant to recessive
transition of the bus signal an additional external termination resistor of 1 k is required,
when the LIN node is used as a master. This termination resistor will automatically be
turned off via the “Master Termination Switch” pin (MTS) once the LIN module enters LIN
Sleep Mode or when the SBC enters Sleep Mode. The transceiver is protected against
short to battery and short to GND.
For LIN automotive applications in the United States a dedicated mode by the name
“Low Slope Mode” can be used. This mode limits the maximum data transmission rate
to 10.4 kBaud by switching to a different slew rate. Operating with the default slew rate
at up to 20 kBaud may cause interferences with the AM radio band.
A bus wake-up via a LIN message (minimum dominant time
mode sets the RxD pin and the WKO pin to low. in addition the MTS is switched ON. The
LIN transceiver has to be enabled to reset the wake-up capability after a bus wake event
and after power-up.
In case of a “TxD dominant time out failure” or a “transmitter thermal shutdown” the SPI
bit 9 is set. After a SPI read-out this bit will be reset unless one of the failure conditions
is still present.
Note: In case of a short to GND on the LIN bus a RxD dominant signal is generated by

the SBC. In the case that RxD is dominant the device can not go into low power
mode from normal mode.
