TJA1055T Enhanced fault-tolerant CAN transceiver

The TJA1055 is the interface between the protocol controller and the physical bus wires in a Controller Area Network (CAN). It is primarily intended for low-speed applications up to 125 kBd in passenger cars. The device provides differential receive and transmit capability but will switch to single-wire transmitter and/or receiver in error conditions. The TJA1055 is the enhanced version of the TJA1054 and TJA1054A. TJA1055 has the same functionality but in addition offering a number of improvements. The most important improvements of the TJA1055 with respect to the TJA1054 and TJA1054A are:

Improved ElectroStatic Discharge (ESD) performance
Lower current consumption in sleep mode
Wake-up signalling on RXD and ERR without VCC active
3 V interfacing with microcontroller possible with TJA1055T/3

产品特点 Features

Optimized for in-car low-speed communication

Pin-to-pin compatible with TJA1054 and TJA1054A
Baud rate up to 125 kBd
Up to 32 nodes can be connected
Supports unshielded bus wires
Very low ElectroMagnetic Emission (EME) due to built-in slope control function and a very good matching of the CANL and CANH bus outputs
Very high ElectroMagnetic Immunity (EMI) in normal operating mode and in low power modes
Fully integrated receiver filters
Transmit Data (TxD) dominant time-out function
High ESD robustness:
- +-8 kV Electrostatic Discharge (ESD) protection Human Body Model (HBM) for off-board pins
- +-6 kV Electrostatic Discharge (ESD) protection IEC 61000-4-2 for off-board pins
Low-voltage microcontroller support

Bus failure management

Supports single-wire transmission modes with ground offset voltages up to 1.5 V
Automatic switching to single-wire mode in the event of bus failures, even when the CANH bus wire is short-circuited to VCC
Automatic reset to differential mode if bus failure is removed
Full wake-up capability during failure modes

Protections

Bus pins short-circuit safe to battery and to ground
Thermally protected
Bus lines protected against transients in an automotive environment
An unpowered node does not disturb the bus lines
Microcontroller interface without reverse current paths, if unpowered

Support for low power modes

Low current sleep mode and standby mode with wake-up via the bus lines
Software accessible power-on reset flag
