TJA1043TK High-speed CAN transceiver
The TJA1043 is a high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed (up to 1 Mbit/s) CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.
The TJA1043 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1041A. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroMagnetic Discharge (ESD) performance, very low power consumption, and passive behavior when the supply voltage is turned off. Advanced features include:
- Low-power management controls the power supply throughout the node while supporting local and remote wake-up with wake-up source recognition
- Several protection and diagnostic functions including bus line short-circuit detection and battery connection detection
- Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V
These features make the TJA1043 the 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
