NXP Semiconductors TJA1044 Mantis® High-Speed CAN Transceivers

NXP Semiconductors TJA1044 Mantis® High-Speed Controller Area Network (CAN) Transceivers with Standby Mode are designed for high-speed CAN applications in the automotive industry. TJA1044 provides an interface between a CAN protocol controller and the physical two-wire CAN bus and the differential transmit/receive capability to (a microcontroller with) a CAN protocol controller. These transceivers feature exemplary passive behavior to the CAN bus when the supply voltage is off, very low-current Standby mode with bus wake-up capability, and excellent EMC performance (speeds up to 500kbit/s) without a common mode choke. The NXP TJA1044 Mantis High-Speed CAN Transceivers are optimized for 12V automotive applications.

Features

Fully ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5, and SAE J1939-14 compliant
Very low-current Standby mode with local and bus wake-up capability
Optimized for use in 12V automotive systems
Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI), according to proposed EMC Standards IEC 62228-3 and SAE J2962-2
Variant options
- A V_IO pin allows for direct interfacing with 3.3V to 5V microcontrollers
- Without a V_IO pin, interface with 3.3V (except TJA1044C) and 5V-supplied microcontrollers, provided the microcontroller I/Os are 5V tolerant
Shorter propagation delay on the TJA1044B and TJA1044C variants that support larger network topologies
Both V_IO and non-V_IO variants are available in SO8 and leadless HVSON8 (3.0mm²) packages, HVSON8 features improved Automated Optical Inspection (AOI) capability
Predictable and fail-safe behavior
- Functional behavior predictable under all supply conditions
- Transceiver disengages from the bus (high-ohmic) when the supply voltage drops below the switch-off undervoltage threshold
- Transmit Data (TXD) dominant time-out functions
- Internal biasing of TXD and STB input pins

Low-power management
- Very low-current Standby mode with host and bus wake-up capability
- Variants
  - With a V_IO pin – CAN wake-up receiver powered by V_IO allowing the V_CC to be shut down
  - With V_IO pin and TJA1044C – CAN wake-up pattern filter time of 0.5μs to 1.8μs, meeting Classical CAN and CAN FD requirements
Protection
- High ESD handling capability on the bus pins (8kV IEC and HBM)
- Bus pins protected against transients in automotive environments
- Undervoltage detection on V_CC and V_IO pins
- Thermally protected
TJA1044 CAN FD (applicable to all product variants except TJA1044T) – Timing guaranteed for CAN FD data rates up to 5Mbit/s
AEC-Q100 qualified
Dark green product [halogen-free and Restriction of Hazardous Substances (RoHS) compliant]
