TJA1043T,118

The TJA1043T,118 is a high-speed CAN (Controller Area Network) transceiver from NXP Semiconductors, designed specifically for automotive applications requiring robust and reliable communication. This third-generation CAN transceiver offers significant improvements over its predecessors, such as enhanced Electromagnetic Compatibility (EMC) and ElectroMagnetic Discharge (ESD) performance, very low power consumption, and passive behavior when the supply voltage is turned off.

The TJA1043T,118 provides an interface between a CAN protocol controller and the physical two-wire CAN bus, offering differential transmit and receive capability to a microcontroller with a CAN protocol controller. It implements the CAN physical layer as defined in the ISO11898 standard, enabling reliable communication at data rates up to 5 Mbit/s in the CAN FD (Flexible Data-Rate) fast phase.

This transceiver is suitable for 12V and 24V systems and offers several protection and diagnostic functions, including bus line short-circuit detection and battery connection detection. It can be interfaced directly to microcontrollers with supply voltages from 3V to 5V and features a SPLIT voltage output for stabilizing the recessive bus level.

The TJA1043T,118 also includes advanced power management features, such as low-power Standby and Sleep modes, with local and remote wake-up capabilities. The transceiver disengages from the bus (zero load) when the VBAT is absent, and its functional behavior is predictable under all supply conditions.

Overall, the TJA1043T,118 is an ideal choice for high-speed CAN networks containing nodes that need to be available all times, even when the internal VIO and VCC supplies are switched off. Its combination of high performance, reliability, and advanced features makes it well-suited for automotive applications such as battery management systems, motor controllers, and intelligent driving assistance systems.
