2 Description
The CAN-Transceiver TLE 6254-2G works as the interface between the CAN protocol
controller and the physical CAN bus-lines.
It is optimized for low-speed data transmission (up to 125 kBaud) in automotive and
industrial applications.
While no data is transferred, the power consumption can be minimized by multiple low
power modes.
In normal operation mode a differential signal is transmitted/received. When bus wiring
failures are detected the device automatically switches in a dedicated single-wire mode
to maintain communication.

Circuit Description
5 Circuit Description
The CAN transceiver TLE 6254-2G works as the interface between the CAN protocol
controller and the physical CAN bus-lines. Figure 3 shows the principle configuration of
a CAN network.
The TLE 6254-2G is optimized for low-speed data transmission (up to 125 kBaud) in
automotive and industrial applications.
In normal operation mode a differential signal is transmitted/received. When bus wiring
failures are detected the device automatically switches in a dedicated single-wire mode
to maintain communication.
While no data is transferred, the power consumption can be minimized by multiple low
power operation modes. Further a receive-only mode is implemented.
To reduce radiated electromagnetic emission (EME) the dynamic slopes of the CANL
and CANH signals are both limited and symmetric. This allows the use of an unshielded
twisted or parallel pair of wires for the bus. During single-wire transmission (one of the
bus lines is affected by a bus line failure) the EME performance of the system is
degraded from the differential mode.
In case the transmission data input TxD is permanently dominant, both, the CANH and
CANL transmitting stage are disabled after a certain delay time. This is necessary to
prevent the bus from being blocked by a defective protocol unit or short to GND at the
TxD input.
