Product Overview: NXP TJA1044T/1 CAN Transceiver

The NXP TJA1044T/1 is a high-speed CAN (Controller Area Network) transceiver designed to provide a reliable interface between the CAN protocol controller and the physical two-wire CAN bus. This transceiver is part of NXP's leading-edge automotive product line, specifically engineered to meet the stringent requirements of in-vehicle networks. It is suitable for use in a wide range of automotive applications, including powertrain, body control, and infotainment systems.

The TJA1044T/1 is optimized for high-speed CAN applications up to 1 Mbps. It features a very low current Standby mode with bus wake-up capability that makes it particularly well-suited for systems that require low power consumption. This transceiver also includes a battery-friendly Silent mode in which the transmitter is disabled, allowing for a reduction in system power consumption while maintaining the ability to listen on the bus.

Key Features:

• Compatible with the ISO 11898-2:2016 standard.
• Support for CAN FD for faster data transmission.
• Differential receiver with wide common-mode range for high electromagnetic immunity.
• Transmit Data (TXD) dominant time-out function to prevent bus line lock-up.
• Integrated thermal protection and an undervoltage detection feature.
• Remote wake-up capability through the bus.
• Very low-current Standby and Silent modes to minimize power consumption.

Applications:

• Automotive networks such as powertrain and body control modules.
• Industrial automation systems requiring robust communication.
• Heavy machinery and agricultural vehicles.
• Maritime electronics and avionics systems.

The TJA1044T/1 is available in an SO-14 package, which is suitable for surface-mount technology (SMT) and is designed to withstand the harsh conditions found in automotive environments. With its advanced features and proven reliability, the NXP TJA1044T/1 is an excellent choice for designers looking to implement a high-speed CAN network with minimal power consumption.
