Overview
The TCAN1046V-Q1 from Texas Instruments is a dual, high-speed Controller Area Network (CAN) transceiver designed for automotive applications. It 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 Mbps. The device features independent mode control for each CAN channel, allowing for low-power standby mode with remote wake-up capability. It is qualified under the AEC-Q100 standard, ensuring reliability over a temperature range of -40°C to 125°C.
