The true beauty of a car isn’t in the way that it looks, but in the way it makes you feel. With the growing demand for smarter vehicles, in-vehicle systems are evolving to provide more seamless experiences. More and more vehicles are incorporating in-vehicle infotainment systems to provide drivers and passengers a combination of entertainment and information to enhance their experiences.

The infotainment system enables radio, navigation, multimedia and Internet-based applications to be centrally controlled. Furthermore, a range of vehicle status messages can be displayed through the infotainment system.

The most popular communication mechanism in modern vehicles is the Controller Area Network (CAN) bus. CAN and other network protocol support: In order to facilitate interaction between microcontrollers and gadgets, the electrical hardware elements of infotainment systems are coupled via standardised communication protocols like CAN. It is a bi-directional serial communication bus that allows Infotainment system to communicate with ECU, without using any complex wiring. One of the wires is called the CAN_Low (CAN_L) and the other, CAN_High (CAN_H), with a data transfer rate of 1Mbit/s.

ESD protection can be achieved by placing Transient Voltage Suppression (TVS) diodes on a data line to protect the interface during the fast rise time transient events like ESD in less than a nanosecond. The Diotec NUP2105L-AQ protection diode is designed to protect high speed data lines from ESD.

Ultra−low capacitance 30pf and high level of ESD protection up to 30KV, 350 W Peak Power Dissipation per Line (8/20 sec Waveform) and very low reverse leakage current <100nA. This device provides bidirectional protection for each data line with a single compact SOT−23 package, it is available in AEC−Q101 Qualified and PPAP Capable.
