Overview
The TCAN1044DRBRQ1, produced by Texas Instruments, is a high-speed Controller Area Network (CAN) transceiver designed to meet the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. This device is AEC-Q100 Grade 1 qualified, making it suitable for automotive applications. It supports both classical CAN and CAN FD networks with data rates up to 8 Mbps. The transceiver includes internal logic level translation, allowing it to interface directly with 1.8V, 2.5V, 3.3V, or 5V logic levels. It also features a low-power standby mode and wake over CAN, compliant with the ISO 11898-2:2016 defined wake-up pattern (WUP).
