Overview
The TCAN1057A-Q1, produced by Texas Instruments, is a high-speed Controller Area Network (CAN) transceiver designed to meet the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. This device is AEC-Q100 (Grade 1) qualified, making it suitable for automotive applications. It supports both classical CAN and CAN FD networks, with data rates up to 5 Mbps and up to 8 Mbps in simpler networks. The transceiver features integrated protection and diagnostic capabilities, including bus fault protection, undervoltage protection, and thermal shutdown. It also includes silent mode operation and hot-plug capability, ensuring glitch-free operation during power-up and power-down on the bus and RXD output.
