TJA1050T/N,118

The TJA1050T/N,118 is an interface transceiver known for its durability, reliability, and cost effectiveness. It is a patented, cost-effective automotive grade I2C-bus transceiver for the fixed physical layer of the OSI layer. This transceiver is particularly suited for applications that require compliance with automotive safety specifications, such as the functional safety accreditation (ISO 26262).

Application Field: The TJA1050T/N,118 is most commonly used in the automotive field. It is suitable for many applications including gateways, body controllers, brake systems, instrument clusters, infotainment, anti-theft, suspensions, and environmental control systems. It is also suitable for use in other industrial applications such as medical, construction and agricultural equipment.

Working Principle: The TJA1050T/N,118 combines a data line receiver, a data line driver, and a bus memory interface, offering a single-package solution for all I2C communication. It supports a maximum data rate of 1 Mbps and provides improved noise immunity and higher operating temperature range than other traditional interface devices. The device also has an integrated I2C bus load detection image, enabling the system to detect connection faults on the I2C bus. A large internal buffer on the chip can be loaded with a unique 8-bit data which is compared with the content of the received I2C frames. When the data does not match, an End of Frame (EoF) interrupt flag is sent, indicating an error on the bus.

The TJA1050T/N,118 is designed for a wide range of automotive applications and uses a low-voltage signaling to handle long bus line lengths and difficult operating conditions. It also supports up to 5 V supply voltage and has a low-power shutdown mode for improved power efficiency. Moreover, the device has an integrated error detection functionality and most of the host controller interface signals have an interrupt output, which can be used to detect, analyze, and save errors.

In conclusion, the TJA1050T/N,118 is a reliable and cost effective transceiver that offers all the necessary features for automotive applications. This device can provide improved noise immunity, higher operating temperature range and improved power efficiency, making it a great choice for the latest automotive technologies.
