High-Speed CAN Transceiver for Partial Networking

  • This page contains information on a product that is not recommended for new designs.



  • Fully compliant with the ISO 11898-2:2003, ISO 11898-5:2007 and ISO 11898-6:2013 standards
  • Timing guaranteed for data rates up to 2 Mbit/s
  • Autonomous bus biasing according to ISO 11898-6:2013
  • Optimized for in-vehicle high-speed CAN communication
  • No ‘false’ wake-ups due to CAN FD frame detection in TJA1145/FD variants

Designed for automotive applications

  • ±8 kV ElectroStatic Discharge (ESD) protection, according to the Human Body Model (HBM) on the CAN bus pins
  • ±6 kV ESD protection, according to IEC 61000-4-2 on pins BAT and WAKE and on the CAN bus pins
  • CAN bus pins short-circuit proof to ±58 V
  • Battery and CAN bus pins protected against transients according to ISO 7637-3, test pulses 1, 2a, 3a and 3b
  • Suitable for use in 12 V and 24 V systems
  • Available in SO14 and leadless HVSON14 package (3 mm x 4.5 mm) with improved Automated Optical Inspection (AOI) capability
  • AEC-Q100 qualified
  • Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)

Advanced ECU power management system

  • Very low-current Standby and Sleep modes, with full wake-up capability
  • Entire node can be powered down via the inhibit output
  • Remote wake-up capability via standard CAN wake-up pattern or via ISO 11898-6:2013 and ISO 11898-2:2003 compliant selective wake-up frame detection
  • Local wake-up via the WAKE pin
  • Wake-up source recognition
  • Bit rates of 50 kbit/s, 100 kbit/s, 125 kbit/s, 250 kbit/s, 500 kbit/s and 1 Mbit/s supported during selective wake-up
  • Local and/or remote wake-up can be disabled to reduce current consumption
  • Transceiver disengages from the bus when the battery supply is removed
  • VIO input allows for direct interfacing with 3.3 V to 5 V microcontrollers

Protection and diagnosis

  • 16-, 24- or 32-bit SPI for configuration, control and diagnosis
  • Transmit Data (TXD) dominant time-out function with diagnosis
  • Overtemperature warning and shut-down
  • Undervoltage detection and recovery on pins VCC, VIO and BAT
  • Cold start diagnosis (via bits PO and NMS)
  • Advanced system and transceiver interrupt handling

Part numbers include: TJA1145T, TJA1145TK.
