The TJA1145TKJ is a CAN Transceiver from NXP Semiconductors. The device is suitable for use as a CAN FD transceiver for automotive applications, and has a wide range of operating temperatures for reliable operation in harsh environments. It is designed with an integrated DC to DC converter which allows it to be used with both 3.3V or 5V supplies. The device is also capable of providing galvanic isolation between the CAN FD and other communication networks.

The TJA1145TKJ is a very versatile transceiver, as it is capable of sending and receiving both standard and extended CAN FD frames. It is also capable of multi-channel communication, and can be used for multiple bit rate settings. The device provides programmable data rate selection, so that the user can configure it for different protocols and topologies. The transceiver also has very low power consumption, making it suitable for automotive applications with restricted energy availability.

The TJA1145TKJ has an integrated physical layer which is compliant with the ISO 11898-2:2016 standard. It has an ESD clamping protection, which allows it to withstand external noise spikes of up to ±15 kV. It also has an integrated bus wake-up feature which allows the device to be woken up when the bus is pulsed.

The working principle of the TJA1145TKJ is quite simple. When a frame is received, it is first filtered and the frame is then forwarded to the appropriate buffer. The frame is then received by the device and verified for correctness. If the frame is valid, the device will transmit the frame back to the sending node.

The TJA1145TKJ transceiver can be used in a variety of applications. It is particularly suitable for automotive applications, as it is robust enough to withstand the harsh environment and is capable of providing galvanic isolation between the CAN FD and other communication networks. It can also be used in industrial applications, such as robotic control systems, as the device can provide multi-channel communication and is capable of handling high-speed communication.

In summary, the TJA1145TKJ is a versatile transceiver designed for both standard and extended CAN FD frames. It offers programmable data rate selection, low power consumption, and integrated physical layer which is compliant with the ISO 11898-2:2016 standard. The device is suitable for use in a variety of applications, including automotive, industrial, and robotic control systems.
