NXP Semiconductors today launched a new generation of high-speed CAN bus transceiver-TJA1043, its electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance has improved significantly. TJA1043 as the most advanced independent HS-CAN transceiver solution for the nodes to power | voltage regulator control. TJA1043 with the mainstream car manufacturers and OEM manufacturers to design and development, with fail-safe, network diagnostics, and wake-up source recognition. The new transceiver extends NXP's current product line, they include widely used TJA1040, TJA1050, TJA1041 and the recently launched TJA1042 and TJA1051, which makes car manufacturers in improving system performance, quality and reliability while reducing the cost of the entire network.
  With today's automotive electronic systems, the increasing complexity of the auto industry is facing new challenges in reducing energy consumption. Automotive OEM specifications based on the latest design for the car manufacturers TJA1043 control electrical load solution. It has extremely low electromagnetic radiation, can reduce the ring network and can work without the choke coil. TJA1043 also has good tolerance to electromagnetic interference (EMI) and first-class ESD protection. When the power is off, it has very low power consumption is similar to passive components. The combination of these features, you can ensure that the vehicle in accordance with the design and operation, are not expected to affect the electromagnetic environment.
"By developing a stronger performance of a new generation of HS-CAN transceiver, NXP support more automotive applications. As the industry's leading automotive suppliers, NXP commitment to maintain the system in low cost, design and development of more environmental protection, safer and more reliable products. After 15 years of automotive networking development, we can provide coverage an important vehicle network standard comprehensive transceiver product portfolio. "NXP Semiconductor's Senior Director and the CAN / LIN transceivers line general manager, Toni Versluijs said.
As a complete NXP HPMS (high-performance mixed-signal) strategy product, TJA1043 for the automotive industry, high-speed (up to 1 Mbit / s) CAN bus applications. It is the high-speed CAN transceiver TJA1041A upgrade products. Major improvements, including
  ? Optimized EMC and ESD performance
? Support truck applications, 24V power supply
? Reduce the static current consumption
The transceiver is fully in line with ISO 11898-2 and ISO 11898-5 standards, has passed the Automotive Electronics Council (AEC) standard Q100 certification for automotive applications. The transceiver chip is RoHs-compliant package, the environment, does not contain any halogenated flame retardants (the so-called "dark green" environmentally friendly products).
  NXP has the industry's broadest portfolio of transceivers, with 30 kinds of transceiver products, a week more than 100 direct customers to supply millions of products. Such a wide customer base and high volume production to achieve a sustained supply, to ensure that customers benefit from NXP to improve productivity and quality of long-term commitment.
