NXP improves EMC and ESD performance for HS-CAN transceiver

April 29, 2010 | Christoph Hammerschmidt | 222900804
NXP improves EMC and ESD performance for HS-CAN transceiver Improved electromagnetic compatibility (EMC) and better electrostatic discharge performance than existing devices are the main benefits of NXPs new high-speed CAN bus transceiver TJA1043. In addition, the device exhibits fail-safe features, network diagnostics and wake-up source recognition. The device allows car OEMs to reduce in-car network costs at better performance and reliability, NXP claims.

With reduction of fuel consumption and greenhouse gas emission being a paramount topic for OEMs across the board, designers direct their attention also to in-car data networks. These networks can contribute to the overall goal to reduce fuel consumption by reducing its own energy demand. Towards this end, the TJA1043 offers a number of features that all together help to reduce energy consumption. According to the vendor, 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) with 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.

As a design within NXPs 'High Performance Mixed Signal' (HPMS) strategy, the TJA1043 can be used in High-speed CAN applications with data rates of up to 1 Mbit/s. In comparison to NXPs existing CAN controllers, the TJA1043 also offers reduced quiescent current consumption and 24V support for truck applications.

The device complies to ISO 11898-2 and ISO 11898-5 standards. For more information, click
