Product Overview: NXP TJA1055 Enhanced High-Speed CAN Transceiver

The NXP TJA1055 is a robust, high-speed CAN transceiver that serves as an interface between the Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. Designed to provide differential transmit and receive capability to (Micro)Controller Area Networks, the TJA1055 is an essential component for automotive and industrial applications requiring reliable data communication with minimal electromagnetic emissions and high immunity against electromagnetic interference.

Key Features

• ISO 11898-2:2003 Compliant: The TJA1055 meets the ISO standard for high-speed CAN transceivers, ensuring compatibility with the most widely used networking protocol for in-vehicle networks.
• Low-Power Mode: An integrated low-power mode significantly reduces the current consumption when the network is idle or when the node is not required to communicate, contributing to energy efficiency.
• Bus Pins Protection: Enhanced protection against transients on the CAN bus ensures reliable operation in harsh electrical environments.
• Remote Wake-up Capability: The device can be woken up from low-power mode via bus activity, making it suitable for applications that require remote activation.

Applications

The TJA1055 is particularly suited for networking in automotive contexts, such as in powertrain applications, chassis control modules, and advanced driver assistance systems. It is also a good fit for industrial automation systems where a robust and reliable CAN network interface is required.

Technical Specifications

• Voltage range: 4.5 V to 5.5 V
• Temperature range: -40°C to +150°C
• Package: 14-pin SO
• Silent mode in which the transmitter is disabled
• Transmit Data (TXD) dominant time-out function

The NXP TJA1055 is a testament to NXP's commitment to providing advanced solutions for communication within vehicles and industrial equipment. Its features offer a blend of performance, power efficiency, and protection that make it a reliable choice for designers and engineers looking to implement or maintain CAN-based networks.
