TJA1044T,118

Description

Product Details

The TJA1044 is part of the Mantis family of high-speed CAN transceivers. It provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1044 offers a feature set optimized for 12 V automotive applications, with significant improvements over NXP's first- and second-generation CAN transceivers, such as the TJA1040 and TJA1042, and excellent electromagnetic compatibility (EMC) performance. Additionally, the TJA1044 features: • Ideal passive behavior to the CAN bus when the supply voltage is off • A very low-current Standby mode with bus wake-up capability • Excellent EMC performance, even without a common mode choke • Variants with a VIO pin can be interfaced directly with microcontrollers with supply voltages from 3.3 V to 5 V These features make the TJA1044 an excellent choice for all types of HS-CAN, in nodes that require a low power mode with wake-up capability via the CAN bus. The TJA1044 implements the CAN physical layer as defined in ISO 11898-2:2024 third edition and SAE J2284-1 to SAE J2284-5. The TJA1044T is specified for data rates up to 1 Mbit/s. Additional timing parameters defining loop delay symmetry are specified for the other variants. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. The TJA1044B and TJA1044C feature shorter propagation delay, supporting larger network topologies
