Overview
The TCAN1044AEV-Q1 is a high-speed Controller Area Network (CAN) transceiver designed by Texas Instruments. It meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification and is certified for electromagnetic compatibility (EMC) operation. This transceiver is optimized for both classical CAN and CAN FD networks, supporting data rates up to 5 Mbps and up to 8 Mbps in simpler networks. It features internal logic level translation via the VIO pin, allowing direct interfacing with 1.8-V, 2.5-V, 3.3-V, or 5-V logic levels. The device includes several protection features such as thermal-shutdown (TSD), TXD-dominant time-out (DTO), supply undervoltage detection, and ±58-V bus fault protection, making it ideal for stringent automotive system requirements.
