Overview
The TCAN1044-Q1 is a high-speed Controller Area Network (CAN) transceiver designed by Texas Instruments for automotive and transportation applications. This device meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification and supports both classical CAN and CAN FD networks up to 8 megabits per second (Mbps). It is qualified to the AEC-Q100 standard, ensuring reliability in harsh automotive environments with a temperature range of –40°C to 125°C.
The transceiver includes internal logic level translation, allowing it to interface directly with 1.8V, 2.5V, 3.3V, or 5V logic I/Os. It also features various protection mechanisms such as bus fault protection up to ±58V, undervoltage protection, and thermal-shutdown protection, making it robust for use in demanding automotive systems.
