NOVOSENSE automotive-qualified CAN transceiver boosts smart control of vehicle

SHANGHAI,March 1,2023 --As the control of each system in the vehicle is becoming smarter and more automated,the electrical system of vehicle is getting more and more complex. Data exchange is required between different functional systems of the vehicle. Traditional point-to-point data exchange may result in complicated wiring system and high failure rate. Therefore,vehicle manufacturers have defined various vehicle bus standards to reduce the complexity of wiring harness network,failure rate of electronic system,and cost of the vehicle. Among them,CAN bus is the most widely used.

Different from traditional vehicles,new energy vehicles use electric drive systems for driving. Switching of high-power devices causes large voltage and current mutations when charging and discharging,probably causing serious EMC problems,and bringing high EMC performance requirements for bus interface chips widely used in vehicles. For better EMC performance,the complement and perfection of the peripheral circuit in the system is also very important in addition to chip design.

Due to the common-mode high resistance and differential-mode low resistance characteristics of the common-mode inductor,placing the common-mode inductor near the transceiver bus (frame c,recommended value: 100uH) can effectively filter out the high-frequency noise outside the bus and the common-mode noise generated by the CAN transceiver due to signal asymmetry,without affecting the transmission quality of CAN differential signal. Therefore,it can improve the anti-interference ability of the system and reduce the EMI of the system.

Introduction to NOVOSENSE CAN transceiver

As a leading analog & mixed signal IC company,NOVOSENSE Microelectronics provides automotive-qualified CAN transceiver NCA1042x-Q1/NCA1051x-Q1,which has obtained the German C&S conformance report. With the features of high transmission rate & high stability,low power consumption,as well as wide I/O voltage operation range,NCA1042x-Q1/NCA1051x-Q1 are both pin to pin compatible with a lot of chips in the market,allowing developers to test NOVOSENSE's chips without modifying their previous board design.
