TJA1055T/C,512

The TJA1055T/C,512 is a CAN Transceiver, 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 125kBd 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 TJA1055T/C,512 is the enhanced version of the TJA1054 and TJA1054A. TJA1055T/C,512 has the same functionality but in addition offering a number of improvements.

• Pin-to-pin Compatible with TJA1054 and TJA1054A
• Baud Rate up to 125kBd
• Up to 32 Nodes can be Connected
• Supports Unshielded Bus Wires
• EME due to built-in slope control function and a very good matching of 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
• ±8kV Electrostatic Discharge (ESD) Protection Human Body Model (HBM) for Off-board Pins
• ±6kV Electrostatic Discharge (ESD) Protection IEC 61000-4-2 for Off-board Pins
• Low-voltage Microcontroller Support
• Supports Single-wire Transmission
• Modes with Ground Offset Voltages up to 1.5V
• Automatic switching to Single-wire mode in event of bus failures
• Automatic Reset to Differential Mode If Bus Failure is Removed
• Full Wake-up Capability During Failure Modes
• 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 Bus Lines
• Microcontroller Interface without Reverse Current Paths, if Unpowered
• Low Current Sleep Mode and Standby Mode with Wake-up via Bus Lines
• Software Accessible Power-on Reset Flag
