Compatible with OEM specifications, the new TJA1043 enables increased system performance and reduces total system cost
NXP Semiconductors today launched the new TJA1043 - a next generation High Speed-CAN transceiver with significantly improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance levels. The TJA1043 is the most advanced stand-alone HS-CAN transceiver solution providing power supply control for the entire node. Designed and developed in collaboration with key automotive OEMs and suppliers, the TJA1043 exhibits fail-safe features, network diagnostics and wake-up source recognition. Extending NXP's existing portfolio that includes the widely used TJA1040, TJA1050 and TJA1041A and the newly released TJA1042 and TJA1051, the new transceiver enables vehicle manufacturers to push down overall network costs while driving up system performance, quality and reliability.
With the electric system of a modern car getting increasingly complex, the automotive industry faces new challenges in lowering energy consumption. Built on the latest automotive OEM specifications, the TJA1043 provides a solution for the automotive manufacturers to control the electrical load. It exhibits very low ElectroMagnetic Emission (EME), enabling reduced network ringing and allowing choke-less operations. The TJA1043 also has a very high ElectroMagnetic Immunity (EMI) along and state of the art ESD protection. It has very low power consumption and demonstrates passive behavior when the supply voltage is turned off. These combined performance characteristics ensure that the vehicle operates as designed without being affected by its anticipated electromagnetic environment.
“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.
Complementing NXP’s HPMS (High Performance Mixed Signal) strategy, the TJA1043 is designed for high-speed (up to 1 Mbit/s) CAN applications in the automotive industry. It is a step up from the TJA1041A High-Speed CAN transceiver. Major enhancements include
* Improved EMC and ESD performance
* 24V support for truck applications
* Reduced quiescent current consumption
Fully ISO 11898-2 and ISO 11898-5 compliant, the transceiver has been qualified to Automotive Electronics Council (AEC) standard Q100 and is suitable for use in automotive applications. The transceiver is housed in an environmentally friendly, RoHS-compliant package and does not contain any halogenated flame retardants (known as Dark Green).
With more than 30 products, NXP has the broadest transceiver portfolio in the market and supplies millions of transceivers to over a hundred direct customers every week. Such a broad customer base coupled with high volume production enables a sustainable supply and ensures that customers will benefit from NXP's long-term commitment to increase productivity and quality.
