Features

General Features

  • ISO 11898-2:2024 parameter sets A-B, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant
  • ISO 26262, ASIL B compliant
  • Partial networking capability through selective wake-up functionality
  • Configurable general-purpose I/O (GPIO) pins (TJA1445B)
  • Direct transmitter on/off control input (TXEN_N) (TJA1445B)
  • Autonomous bus biasing
  • Low electromagnetic emission (EME) and high electromagnetic immunity (EMI)
  • Qualified according to AEC-Q100 Grade 1
  • VIO input for interfacing with 1.8 V, 3.3 V to 5 V microcontrollers
  • TJA1445A available in SO14 and HVSON14 package
  • TJA1445B available in a DHVQFN18 package

Predictable and Fail-Safe Behavior

  • Undervoltage detection on all supply pins with defined behavior below the undervoltage thresholds
  • Functionality is guaranteed from the undervoltage detection thresholds up to the maximum limiting voltage values
  • Transceiver disengages from the bus (high-ohmic) when the battery voltage drops below the Off mode threshold
  • Internal biasing of TXD to enable defined fail-safe behavior

Low-Power Management

  • Very low-current Standby and Sleep modes, with local and remote wake-up capability
  • Local wake-up via the WAKE pin
  • Remote wake-up via a wake-up pattern (WUP) or wake-up frame (WUF)
  • Configurable CAN wake-up pattern (dom-rec-dom or dom-rec-dom-rec) according to ISO 11898-2:2024
  • Selective wake-up according to ISO 11898-2:2024

Diagnosis and Protection

  • Overtemperature diagnosis and protection
  • Transmit data (TXD) dominant time-out diagnosis and protection
  • Bus dominant failure diagnosis
  • Cold start diagnosis (first battery connection)
  • High ESD handling capability on the bus pins
  • Bus pins and VBAT protected against automotive transients
