Overview
The TCAN1043DRQ1 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, supporting both classical CAN and CAN FD (Flexible Data Rate) up to 2 Mbps, with variants supporting up to 5 Mbps. This device is AEC Q100 qualified for automotive applications and is functional safety-capable, making it suitable for a wide range of automotive and industrial applications. The TCAN1043DRQ1 features advanced power management, including low-power sleep modes and wake-up capabilities, to reduce system-level battery current consumption.
