The TJA1040T/N1,112, an integrated circuit device from the Interface - Drivers, Receivers, Transceivers category, is a transceiver providing the ability to bridge communication between different bus systems using either single-wire, UART (universal asynchronous receiver/transmitter), or LIN (local interconnect network) protocol. It can operate as a node or master, making it suitable for applications in which nodes, controllers, and masters must communicate to optimize communication. The TJA1040T/N1,112 is a combination of a universal asynchronous receiver/transmitter (UART), a LIN transceiver, and a current limiter with a wide supply voltage range and a low-current operating mode.

The TJA1040T/N1,112 application field includes industrial automation, building automation, consumer electronics, motor control, and systems that require communication via bus systems. Primarily, it is used where UART, LIN, and/or single-wire communication is needed. The combination of UART, LIN transceiver, and current limiter make it suitable for automotive applications, where the microcontroller must communicate with various sensors and the vehicle’s bus system.

The TJA1040T/N1,112 works on the principle of exchanging information between two or more devices via a medium. It supports a maximum of two communication protocols, UART and LIN, as well as single-wire communication. UART means Universal Asynchronous Receiver/Transmitter. Its duty is to transmit and receive data between two devices using predetermined transmitted and received protocol. LIN means Local Interconnect Network. It is a single-wire protocol used in automotive applications that bridges communication between a master and slave node.

In addition, the TJA1040T/N1,112 is a current limiter with a wide supply voltage range and a low-current operating mode. The circuit acts as a buffer which is placed between the transmitter and the receiver nodes; it controls the level of current. If a peak current rises, it cuts back the current when it exceeds the safe level for a certain period of time. This prevents damage to the system.

The TJA1040T/N1,112 transceiver combines UART, LIN transceiver and current limiter functions. It provides single-wire, UART, and LIN communication with the highest performance available, plus additional flexibility and protection from current surges in the power supply or high voltage spikes input to the system. This is why the TJA1040T/N1,112 is an ideal choice for applications in which nodes, controllers, and masters must communicate to optimize communication.
