The TJA1051T/3,118 is a high-speed CAN (Controller Area Network) transceiver designed by NXP Semiconductors. It serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. This transceiver is particularly well-suited for automotive applications and industrial automation systems where robust communication and high noise immunity are required.
Key Features
-
High-Speed CAN Interface: Supports the ISO 11898-2:2016 standard, allowing for data transfer rates up to 1 Mbit/s.
-
Improved Electromagnetic Compatibility (EMC): Enhanced features for reducing electromagnetic emissions and improving immunity to electromagnetic interferences.
-
Low Power Mode: Features a very low current standby mode with remote wake-up capability, making it suitable for power-sensitive applications.
-
Transmit Data (TXD) Dominant Time-out Function: Prevents the bus line from being driven to a permanent dominant state due to a faulty controller.
-
Thermal Protection: Incorporated thermal protection disables the transmitter in the event of a short-circuit at the CANH or CANL outputs.
-
Bus Pins Protected Against Transients: Provides additional resilience in harsh electrical environments.
