TJA1044

High-speed CAN transceiver with Standby mode

Rev. 6 — 24 August 2017

Product data sheet

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.
