TJA1055T/3/1

The TJA1055T/3/1 from NXP Semiconductors is an enhanced fault-tolerant CAN transceiver, serving as the interface between the protocol controller and the physical bus wires in a Controller Area Network (CAN).

This device is primarily intended for low-speed applications, supporting baud rates up to 125 kBd and allowing up to 32 nodes to be connected on the bus. It features differential receive and transmit capabilities, with automatic switching to single-wire modes in error conditions. Key electrical characteristics include high ESD robustness, with ±8 kV protection according to the Human Body Model (HBM) and ±6 kV according to IEC 61000-4-2 for off-board pins. It also supports single-wire transmission modes with ground offset voltages up to 1.5 V.

The TJA1055T/3/1 is designed for reliability in automotive environments, offering features like bus failure management, thermal protection, and protection against transients. It supports low-power modes with low current consumption in sleep mode and wake-up capability via the bus lines. The transceiver is pin-to-pin compatible with previous versions like the TJA1054 and TJA1054A, offering improved ESD performance and lower current consumption.

Packaged in a 14-SOIC surface-mount package, this CAN transceiver is suitable for various automotive in-car communication systems. Its design prioritizes very low electromagnetic emission (EME) and very high electromagnetic immunity (EMI).
