Overview
The TJA1043AT/0Z is a high-speed CAN (Controller Area Network) transceiver designed by NXP USA Inc. for applications in the automotive industry. This transceiver provides an interface between a CAN protocol controller and the physical two-wire CAN bus, ensuring reliable communication at data rates up to 5 Mbit/s in the CAN FD fast phase. It is part of the third generation of high-speed CAN transceivers, offering significant improvements in ElectroMagnetic Compatibility (EMC), ElectroStatic Discharge (ESD) performance, and low power consumption. The TJA1043AT/0Z is compliant with ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 standards, making it an ideal choice for high-speed CAN networks that require continuous availability even when the internal supplies are switched off.
