To achieve the required timings for the dominant to recessive transition of the bus signal an additional external
termination resistor of 1 kΩ is mandatory. It is recommended to place this resistor at the master node. To avoid
reverse currents from the bus line into the battery supply line it is recommended to place a diode in series with the
external pull-up. For small systems (low bus capacitance) the EMC performance of the system is supported by an
additional capacitor of at least 1 nF at the master node (see
Termination resistor and the bus capacitances influence the performance of the LIN network. They depend on the
number of nodes inside the LIN network and on the parasitic cable capacitance of the LIN bus wiring.
