Overview
The TCAN1044AVDRQ1 is a high-speed Controller Area Network (CAN) transceiver designed by Texas Instruments for demanding automotive applications. It meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification and is AEC-Q100 (Grade 1) qualified, ensuring reliability and compliance with automotive standards. The transceiver supports both classical CAN and CAN FD networks up to 5 megabits per second (Mbps) and can operate at higher data rates in simpler networks, up to 8 Mbps. It features internal logic level translation, allowing direct interface with various logic levels (1.8V, 2.5V, 3.3V, or 5V), and includes a low-power standby mode with wake-up over CAN capability.
