Overview
The TCAN1057AVDRQ1 is a high-speed Controller Area Network (CAN) transceiver designed by Texas Instruments. This device is AEC-Q100 (Grade 1) qualified, making it suitable for automotive applications. It meets the requirements of the ISO 11898-2:2016 physical layer standard for high-speed CAN networks. The transceiver supports both classical CAN and CAN FD protocols, with data rates up to 5 Mbps and up to 8 Mbps in simpler networks. It features functional safety capabilities and is designed to aid in functional safety system design.
The device includes various protection features such as bus fault protection up to ±58V, undervoltage protection, and thermal shutdown protection. It operates in normal and silent modes, with hot-plug capability for glitch-free operation during power-up and power-down. The TCAN1057AVDRQ1 also includes an integrated level shifter for interfacing with different logic levels (1.8V, 2.5V, 3.3V, or 5V).
