High-Speed CAN Transceiver with Standby Mode - Mantis Family
For security on TJA1042, TJA1044, TJA1049, go to Secure CAN TJA1152, for higher data rates on these devices, go to CAN SIC TJA1462.
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. 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 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 the current 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.

Features
General 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 12 V automotive systems
- Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI),according to proposed EMC Standards IEC 62228-3 and SAE J2962-2
- AEC-Q100 qualified
- Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
- Variants with a VIO pin allow for direct interfacing with 3.3 V to 5 V microcontrollers
- Variants without a VIO pin can interface with 3.3 V (except TJA1044C) and 5 V-supplied microcontrollers, provided the microcontroller I/Os are 5 V tolerant
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
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 pin VCC
- Thermally protected
TJA1044GT/TJA1044GTK
