Overview
The TCAN1044-Q1, produced by Texas Instruments, is a high-speed Controller Area Network (CAN) transceiver designed to meet the stringent requirements of automotive and transportation systems. This device complies with the physical layer standards of ISO 11898-2:2016 and ISO 11898-5:2007, ensuring compatibility with both classical CAN and CAN FD networks up to 8 megabits per second (Mbps). It is AEC-Q100 qualified with a temperature grade 1 rating, operating from –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, and features various protection mechanisms such as bus fault protection, undervoltage protection, and thermal-shutdown protection.
