7.2
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 in the master node (see
7.3
A capacitor of 22 µF at the supply voltage input
reverse polarity diode this prevents the device from detecting power down conditions in case of negative transients
on the supply line.
The 100 nF capacitors close to the
behavior of the system.
