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:
sot108-1_3d
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
