LIN Transceiver
The TLE7824G offers a LIN transceiver, which is compatible to ISO9141 and certified according to LIN
Specification 1.3 and 2.0 “Physical Layer”. The transceiver has a pull-up resistor of 30 kΩ implemented and is
protected against short to battery and short to GND.
The LIN transceiver has an implemented wake-up capability during operation in power saving modes. In Stop
Mode a wake-up event is indicated via (internal) RxD and DO signals, that are pulled “low”. Out of Sleep Mode a
wake-up event causes an automatic transition into Standby Mode and the (internal) RxD and DO signals are pulled
“low”. If the TxD input is pulled low for longer than the TxD dominant timeout the TxD input is ignored and the LIN
bus goes back to recessive state. This fail-safe feature in case of a permanent low TxD signal recovers if the TxD
pin is high for TxD dominant timeout recovery time.
For LIN automotive applications in the United States a dedicated mode by the name “Low Slope Mode” can be
used. This mode reduces the maximum data transmission rate of 20 kBaud to 10.4 kBaud by switching to a
different slew rate. By using this mode the EM noise emission can be reduced.
