Texas Instruments TCAN1044x/TCAN1044x-Q1 CAN Transceivers
Texas Instruments TTCAN1044x/TCAN1044x-Q1 Fault-Protected High-Speed CAN Transceivers meet the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. The TCAN1044x/TCAN1044x-Q1 transceivers support classic CAN and CAN FD networks, up to 8Mbps. The TCAN1044x/TCAN1044x-Q1 transceivers include internal logic level translation via the VIO terminal, allowing interfacing the transceiver IOs directly to 1.8V, 2.5V, 3.3V, or 5.0V logic IOs.
The TCAN1044x/TCAN1044x-Q1 CAN Transceivers have a low-power standby mode, which supports remote wake-up via the ISO 11898-2:2016 defined wake-up pattern (WUP). The TCAN1044x/TCAN1044x-Q1 Transceiver also includes many protection and diagnostic features, including thermal-shutdown (TSD), TXD-dominant time-out (DTO), supply under-voltage detection, and bus fault protection up to ±58V.
The Texas Instruments TCAN1044-Q1/TCAN1044V-Q1 devices are AEC-Q100 qualified for automotive applications.
