The TJA1041T/N,118 is an automotive transceiver for the local interconnect network and a communication interface for ISO 11898-2. The transceiver is a physical layer chip and provides the link between a controller area network (CAN) bus and the physical bus. It features very low standby power consumption, wide temperature range, and output edge rates of up to 1 Mbps.

The TJA1041T/N,118 is used in a wide range of applications including automotive, industrial, and other areas. It is used to provide a reliable, robust, and error-free communication interface between CAN protocols and any physical layer interfaces that use the ISO 11898-2 standard, such as CAN FD, LIN, and Ethernet. The transceiver provides a robust and noise immune communication channel which ensures the integrity of data on the bus.

The working principle of the TJA1041T/N,118 is essentially an open-drain driver using the voltage levels of its associated bus line. In bus idle mode, the driver is placed in the tri-stated i.e. not sending any information. However, when the controller application requires data to be transferred, the CAN controller issues a control signal to the driver to become active. At this stage, the transmitted signal is applied to the open-drain driver and the device acts as a bidirectional line driver / receiver.

The data structure of the TJA1041T/N,118 includes a 4-bit register addressed by two bits for configuration, fast data, and slow data. This allows for the driver to detect the data in both directions within one frame. The converted signals are then processed by the transceiver and send the respective signals to the transceiver controller according to the bus levels. The transceiver also comes with an integrated watchdog timer that serves as a safety mechanism to guarantee data transmission.

The TJA1041T/N,118 is compatible with the ISO 11898-2 standard and is a reliable, cost-effective alternative which meets the stringent legal requirements. Moreover, the transmitter is fast enough to support the latest CAN FD application and provides extremely low power consumption when in standby mode. This makes the TJA1041T/N,118 the ideal choice for smart power management in applications that require low-power communications.

The transceiver is widely used in a variety of applications including automotive, industrial, and consumer electronics. In automotive applications it is used in various systems such as sensors, body controllers, auto diagnostics, powertrain controllers, green technology, and safety systems. The transceiver is also used in industrial systems such as automation systems, robotics, and HVAC systems. Additionally, it is used in consumer electronics for home automation, security systems, and medical diagnostics.

The TJA1041T/N,118 is a versatile and cost-effective transceiver designed to provide robust and reliable communication between CAN and any physical layer interface according to the ISO 11898-2 standard. With its integrated watchdog timer, low standby power consumption, and wide temperature range, the TJA1041T/N,118 is an ideal solution for automotive and industrial applications.
