Overview

The TJA1055T/3/CM,118 is an enhanced fault-tolerant CAN transceiver designed for low-speed CAN applications up to 125 kBd. It serves as the interface between a CAN protocol controller and the physical bus, featuring the ability to switch to a single-wire mode in the event of bus wire failures. This device is specifically optimized for automotive and industrial environments where robust communication and low power consumption are critical.

Why Choose This Part

The transceiver offers integrated receiver filters and a TxD dominant time-out function to prevent bus latch-up. It supports 3V interfacing with microcontrollers and maintains low power consumption with a sleep current of only 25uA. Its ability to automatically reset to differential mode after a bus failure is removed simplifies system recovery and increases network uptime.

Applications

Automotive Body Control
Ideal for comfort electronics such as door modules, seat control, and climate systems where fault tolerance ensures continued operation during wiring faults.
Industrial Networking
Used in factory automation systems requiring robust communication over long cable runs susceptible to ground offsets or cable damage.
Low-Speed CAN Networks
Specifically designed for CAN networks operating at speeds up to 125 kBd that prioritize reliability over high data throughput.

Getting Started

To evaluate this transceiver, integrate it with a CAN controller such as those found in S32K or LPC microcontrollers using standard 1.27mm SO14 footprint prototyping boards. Ensure the Vcc supply is stable between 4.75V and 5.25V and implement the required termination resistors for fault-tolerant CAN topologies as specified in the NXP application notes. Monitor the ERR pin to detect and diagnose bus failure conditions during firmware development.
