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

  • Timing guaranteed for data rates up to 5 Mbit/s
  • Improved TXD to RXD propagation delay of 210 ns

Product Longevity Program

  • These products are included in the NXP Product Longevity Program ensuring a stable supply of products for your embedded designs. The TJA1044B and TJA1044G are included in the 15-year program
