TJA1044V Block Diagram



  • 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.
  • TJA1044VT/3 and TJA1044VTK/3 can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V.
  • 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 TJA1044Vx/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 x 3.0 mm) packages; HVSON8 with improved Automated Optical Inspection (AOI) capability.


  • 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.

Automotive Certifications/Standards

  • Fully ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant.
  • Certified according to latest VeLIO (Vehicle LAN Interoperability and Optimization) test requirements.

Part numbers include: TJA1044VT, TJA1044VTK.
