TJA1445/TJA1446 High-Speed CAN Transceivers

NXP Semiconductors TJA1445 and TJA1446 Advanced High-Speed CAN Transceivers feature a partial networking sleep mode and implement CAN FD as defined in ISO11898-2:2024 parameter sets A-B. These NXP Semiconductors TJA144x transceivers are fully interoperable with the high-speed classical CAN and CAN FD protocols and have been fully developed and certified to be ISO 26262 ASIL-B compliant. TJA144x supports CAN partial networking using selective wake-up functionality (as specified in ISO 11898-2:2024), allowing the transceiver to remain in sleep mode even when CAN bus traffic is running (when it is not required to be active). The TJA1445 offers a CAN FD passive feature (in sleep mode) that prevents the transceiver from waking up and shields the CAN controller from CAN FD messages when running a mixed bus communication. The TJA1446 offers that feature and also shields from CAN XL messages.
