Functional Description The CAN Transceiver works as the interface between the CAN protocol controller and the physical differential CAN bus. Figure 1 shows the principle configuration of a CAN network. The TLE 6252 is optimized for low-speed data transmission (up to 125 k Baud) 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 single-wire mode to maintain communication. While no data is transferred, the power consumption can be minimized by multiple low power modes.
