CAN transceivers with higher EMC and ESD performance by NXP Semiconductor

NXP has introduced a high speed-CAN transceiver, TJA1043 with high Electromagnetic Compatibility (EMC) and Electrostatic Discharge (ESD) performance levels. This is an advanced stand-alone HS-CAN transceiver solution providing power supply control for the entire node.

The TJA1043 with features such as fail-safe features, network diagnostics and wake-up source recognition is designed to deliver high-speed (1 M bits/s) performance and reliability at lower costs. TJA1043 is fully ISO 11898-2 and ISO 11898-5 compliant and has been qualified to Automotive Electronics Council (AEC) standard Q100. TJA1043 is a better replacement for TJA1041A High-Speed CAN transceiver.

"By developing this new and enhanced generation of HS-CAN transceivers, NXP is supporting the increase of electronic applications in the car. As a leading automotive supplier, NXP is committed to design and develop products that are greener, safer and more reliable while keeping the system costs low. Building on 15 years of in-vehicle network (IVN) developments, we offer a complete transceiver portfolio covering key automotive network standards," said Toni Versluijs, Senior Director and General Manager CAN/LIN Transceivers, NXP Semiconductors.
