The TLE 6254-2G detects the bus failures as described in Table 3, and automatically
switches to a dedicated CANH or CANL single wire mode to maintain data transmission
if necessary. Therefore, the device is equipped with one differential receiver and 4 single
ended receivers, two for each bus line. To avoid false triggering by external RF
influences the single wire modes are only activated after a certain delay time. As soon
as the bus failure disappears the transceiver switches back to differential mode after
another time delay. Bus failures are indicated in the normal operation mode by setting
the NERR output low.
The differential receiver threshold is typ. – 2.8 V. This ensures correct reception in the
normal operation mode as well as in the failure cases 1, 2 and 4 with a noise margin as
high as possible. For these failures, further failure management is not necessary.
Detection of the failure cases 1, 2, 3a and 4 is only possible when the bus is dominant.
Nevertheless, they are reported on the NERR output until transmission of the next CAN
word on the bus begins.
