TJA1054AT/N,118: Application Field and Working Principle

The TJA1054AT/N,118 is an interface IC that is used to transceiver data between two networks such as an automotive DC bus and an automotive DC bus compatible to PHY. It offers excellent optimized power dissipation, compact footprint, allowing the device to fit in many space constrained applications; along with low current consumption, integrated Thermal Shutdown protection, and excellent error detection and correction capability.

TJA1054AT/N,118 is commonly used in in-vehicle and industrial automation networks, where connectivity and data integrity are important, as it provides highly reliable data communication. The transceiver is used in low latency systems such as Automotive CAN, PC Engine and HVAC, and in industrial networks such as Profinet, Profibus, LonWorks, and Sensor.

The TJA1054AT/N,118 is designed in accordance to ISO 11898-2 standards and consists of an integrated transmitter and receiver, twisted-pair transformer and electrical protection. The device also has a built-in tolerance to leakage currents of up to 25mA, helping reduce interference and making it suitable for safe, high speed CAN communication. It supports up to 200 Kilo-bits per second bidirectional data transmission while working with 3V-5V power supply.

The TJA1054AT/N,118 works by converting the data from the CAN bus to transmit signals and noise onto the CAN and then sending the signals to the receiving device, further decoding and processing it to be sent out onto the receiver. The signals are then amplified in the receiving device and transmitted onto the CAN bus as analog signals. This way, the data packets can be passed from one device to another without any errors.

The device has various protection systems and test points, along with an integrated ESD protection. Its current consumption rate is very low, often just a few milliamperes. In terms of power saving, it needs only 2mA to remain awake and only 0.25mA for sleep.

The TJA1054AT/N,118 is a versatile device that offers reliable data communication in the automotive and industrial automation networks. Its low power consumption and high data transmission rate make it suitable for a wide range of applications. With its built-in electromagnetic compatibility, it is perfect for applications that require reliable data communication in a noisy environment.
