Application Information
Figure 3
For fail safe reasons the TLE6258-2G has already a pull-up resistor of 30 kΩ
implemented. To achieve the required timings for the dominant to recessive transition of
the bus signal an additional external termination resistor of 1 kΩ 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
1 nF in the master node (see
In order to reduce the current consumption the TLE6258-2G offers a stand-by mode.
This mode is selected by switching the Enable Not (ENN) input high (see
the stand-by mode a wake-up caused by a message on the bus is indicated by setting
the RxD output low. When entering the normal mode this wake-up flag is reset and the
RxD output is released to transmit the bus data.
