Self-Supplied High-Speed CAN Transceiver with Sleep Mode

UJA1162TK
  • Not Recommended for New Designs

  • This part is not recommended for new designs. For new designs, we recommendUJA1162ATK.

The UJA1162 is a ‘self-supplied’ high-speed CAN transceiver integrating an ISO 11898-2/5 compliant HS-CAN transceiver and an internal 5 V CAN supply. The only supply input is a battery connection. The UJA1162 can be operated in a very low-current Sleep mode with local and bus wake-up capability.

The UJA1162 implements the standard CAN physical layer as defined in the current ISO11898 standard (-2 and -5). Pending the release of the updated version of ISO11898 including CAN FD, additional timing parameters defining loop delay symmetry are included. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 2 Mbit/s.
