1. General description 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 at speeds up to 500 kbit/s, even without a common mode choke ? TJA1044GT/3 and TJA1044GTK/3 can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V These features make the TJA1044 an excellent choice for all types of HS-CAN networks, 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 11898-2:2016 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. 2. Features and benefits 2.1 General ?
