Summary form only given. The automotive environment poses many difficult challenges for the use of semiconductors in a car. Several challenges are common for the whole semiconductor industry, but many are very specific for automotive applications. Specific automotive requirements are e.g. high reliability, very high safety, high voltage, high temperature, low EMC emission and high immunity for EMC, ESD and battery voltage transients: This paper discusses the evolution of these requirements and how these challenges are addressed during the design of ICs for automotive applications.
