Overview
The TJA1145ATK/FD/0Z is a high-speed CAN (Controller Area Network) transceiver designed by NXP USA Inc. for automotive applications. This device is optimized for in-vehicle high-speed CAN communication, complying with ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 standards. It features advanced power management, autonomous bus biasing, and support for CAN FD (Flexible Data Rate) communication up to 5 Mbit/s. The transceiver is particularly suited for applications where nodes are always connected to the battery supply line but need to minimize current consumption by being active only when required.
