♠ TJA1044 High-speed CAN transceiver with Standby mode
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.
1 General
Fully ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant
Very low-current Standby mode with host and bus wake-up capability
Optimized for use in 12 V automotive systems
EMC performance satisfies ‘Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Applications’, Version 1.3, May 2012.
AEC-Q100 qualified
Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
VIO input on TJA1044x/3 variants allows for direct interfacing with 3 V to 5 V microcontrollers. Variants without a VIO pin can interface with 3.3 V and 5 V supplied microcontrollers, provided the microcontroller I/Os are 5 V tolerant.
Both VIO and non-VIO variants are available in SO8 and leadless HVSON8 (3.0 mm 3.0 mm) packages; HVSON8 with improved Automated Optical Inspection (AOI) capability.
2 Predictable and fail-safe behavior
Functional behavior predictable under all supply conditions
Transceiver disengages from bus when not powered (zero load)
Transmit Data (TXD) and bus dominant time-out functions
Internal biasing of TXD and STB input pins
3 Protection
High ESD handling capability on the bus pins (8 kV IEC and HBM)
Bus pins protected against transients in automotive environments
Undervoltage detection on pins VCC and VIO
Thermally protected
