Data Sheet
6.0 Typical Application
6.1 Application Schematic
The EMC immunity of the master-mode device can be further enhanced by adding a capacitor between the LIN output and ground. The
optimum value of this capacitor is determined by the length and capacitance of the LIN bus, the number and capacitance of slave
devices, the pull-up resistance of all devices (master & slave), and the required time constant of the system, respectively.
Vcc voltage must be properly stabilized by external capacitors: capacitor of min. 80nF (ESR<10mâ¦) in parallel with a capacitor of min.
8µF (ESR<1â¦).
