Application Information
Figure 3: operation mode state diagram
Master Termination
For fail safe reasons, the TLE6259-2 already has a pull up resistor of 30k
To achieve the required timings for the dominant to recessive transition of the bus signal
an additional external termination resistor of 1k is required. It is recommended to place
this resistor in the master node. To avoid reverse currents from the bus line into the
battery supply line in case of an unpowered node, it is recommended to place a diode in
series to 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 1nF in the
master node (see figure 6 and 7, application circuit).
implemented.
External Capacitors
An capacitor of 22μF at the supply voltage input V
S
buffers the input voltage. In
combination with the required reverse polarity diode this prevents the device from
detecting power down conditions in case of negative transients on the supply line.
