The TJA1051 is a high-speed CAN transceiver that provides an interface between a CAN protocol controller and a two-wire CAN bus in automotive applications. The TJA1051 delivers differential transmit and receive capabilities and supports reliable high-speed CAN communication. As a third-generation CAN transceiver, it offers enhanced electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance compared to earlier generations. The TJA1051 also features passive behavior when unpowered, and selected variants support direct interfacing with microcontrollers operating from 3 V to 5 V.
