TJA1054T: Fault-tolerant CAN transceiver ARCHIVED

Optimized for in-car low-speed communication

• 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 and low power operating modes
• Fully integrated receiver filters
• Transmit Data (TxD) dominant time-out function

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 V_CC
• 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

Support for low power modes

• Low current sleep mode and standby mode with wake-up via the bus lines
• Power-on reset flag on the output
