TJA1145T,118

The TJA1145T,118 is an interface gateway product used to enable a connection between dissimilar communication networks. This product is broadly classifiable under the category of drivers, receivers, transceivers. The application field and working principle of this product is discussed in the following sections.

Application Field:

The TJA1145T,118 is an interface gateway product used primarily for the purpose of interconnecting vehicles within a local area network (LAN), using a standardized protocol known as CAN (Controller Area Network) together with an additional enhanced protocol CANFlex. CAN is a Communication Protocol that facilitates the transfer of data from one point in a network to another. CANFlex is an additional protocol used for data transmission which is fully compliant with the CAN protocol, but more reliable and optimized for exchanges between dedicated nodes.

The TJA1145T,118 is commonly used in the Automotive Industry, Industrial Automation, and Lightweight Robotics. It is suitable for large scale integration and is reliable to use in distributed systems or on a single board. This product is small in size and low in power consumption. Therefore, it is the perfect choice for applications that require the interconnection of multiple devices in a small enclosure, or for those which require high-speed data transmissions with low latency.

Working Principle:

The TJA1145T, 118 works on Controllers Area Network (CAN) and CANFlex protocols. CAN is a bus system communication protocol that uses a standard format of data packets to exchange information between interconnected devices. This protocol is widely used in the automotive industry to exchange data between microcontrollers. CANFlex is an enhanced version of CAN that uses additional features including error-checking, collision avoidance, and broadcast messaging.

The TJA1145T,118 is a galvanic interface between CAN networks allowing connect and disconnect of devices in a chain. It works by converting data received on either the CAN or CANFlex bus into digital pulses, which then control the transmit and receive of messages across the interface. This product also contains a way to control access rights for external devices, as well as an internal watchdog timer which allows for fault tolerance when an unexpected file is being transmitted.

The device contains up to threepins for connections. Two of these pins are for CAN and CANFlex connections and the third one is for fault detection. The device also has a serial interface which is used to configure the device. The configuration process involves setting-up the data rate, interrupt sources, fault flags, and start-up and shut down parameters.

The device can be used in either master or slave mode. In master mode, the device can actively poll other devices within the network, while in slave mode, it can only respond to requests from the master device. Additionally, the device has an event-driven operating mode which allows it to listen and react to specific events on the bus.

Conclusion:

The TJA1145T,118 is an interface gateway product commonly used in the Automotive Industry, Industrial Automation, and Lightweight Robotics. It works on the CAN and CANFlex protocol, and has three pins for connection, two for CAN and CANFlex connections and one for fault detection. It is capable of master and slave mode, as well as event-driven operating mode for more advanced control, making it suitable for a wide range of applications.
