Overview
The TJA1044GT/3Z is a high-speed CAN (Controller Area Network) transceiver produced by NXP USA Inc. It is part of the Mantis family of CAN transceivers, designed to provide an interface between a CAN protocol controller and the physical two-wire CAN bus. This transceiver is optimized for high-speed CAN applications, particularly in the automotive industry, offering significant improvements over earlier generations of NXP's CAN transceivers. It features a low-current Standby mode with bus wake-up capability, making it an excellent choice for nodes requiring low-power operation with wake-up functionality via the CAN bus.
