The TLE6254-3G is a fault tolerant low speed CAN Transceiver 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 125kBaud). 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. 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 the EME performance of the system is degraded from the differential mode.
