This document describes the features of TJA1054 fault-tolerant CAN transceiver, including optimized for in-car low-speed communication, support for multiple node connections, support for unshielded bus wires, very low Radio Frequency Interference (RFI), fully integrated receiver filters, bus failure management, protection features, and support for low power modes.
The Philips TJA1054 is a fault-tolerant CAN transceiver designed as an interface between a protocol controller and physical bus lines. It is primarily intended for low-speed applications, specifically up to 125 kBaud, in passenger cars.
Key features include support for unshielded bus wires due to built-in slope control functions and very good matching of the CANL and CANH outputs. The device offers automatic switching to single-wire transmission modes in the event of bus failures, such as short-circuits or interruptions, ensuring continued operation even when the CANH bus wire is short-circuited to Vcc.
