汽车 IC 技术令驾驶变得更加平稳
26 November 2018 / by Semtech Corporate Marketing
In 1885, Karl Benz, a German engineer, invented the first functional automobile. Over the past 130 years, automobiles have evolved considerably. Semtech is proud to be a part of the automotive technology journey and is aiding this evolution by offering key technologies that contribute to the advancement of safety, reliability and performance of automobiles. In commemoration of the inventor’s birthday, November 25, we take a look at some key automotive applications for integrated circuits (IC), and highlight Semtech’s contribution (or participation) to their implementation.
Advanced driver assistance systems (ADAS) are a collection of technologies that help keep drivers safe by automating and enhancing specific systems in a vehicle. ADAS includes such technologies as dynamic cruise control, lane keep assist, front and rear collision avoidance, backup cameras and parking assist through multiple cameras integrated around the car. Implementation of ADAS requires very high system reliability and demands the use of solutions that provide elevated electrostatic discharge (ESD) and surge protection for failsafe operation, along with highly efficient power management circuits.
Considered almost essential in all cars, navigation and infotainment capabilities include innovative HD touchscreens for navigation, USB interfaces for connecting smartphones, and connectivity for multiple radio frequency (RF)-based systems with the ability to provide rear-seat entertainment. Distribution of entertainment content within the car is typically done using interfaces such as HDMI 2.1.
Cars today are designed to easily accommodate personal electronic devices. Today’s automobiles feature Bluetooth connectivity and dashboard USB ports to allow for convenient charging of phones and tablets, while providing access to innovative features such as display mirroring and voice communication to smartphone features.
The newest models of cars feature remote keyless entry systems for driver convenience. In many cases, these are two-way systems that display automobile status on the key fob and/or the smartphone.
要确保增强这些关键子系统的稳健性和有效运行，就需要高度复杂的 ESD 和浪涌保护解决方案，以时刻保护这些子系统远离故障。Semtech 拥有符合 AEC-Q100 标准的广泛保护器件系列，被所有大型 OEM 公认为提供高水平的保护。Semtech 的 EcoSpeed® DC-DC 转换器和 EcoBrite™ LED 驱动器能补充保护解决方案，实现各种汽车子系统的节能设计，包括但不限于显示器和信息娱乐系统。Semtech 射频接收器和收发器提供创新平台，能确保车辆安全，并提供双向通信。
