Automotive chips and components: Automotive-grade electronic products
An electric vehicle requires approximately 2000 automotive chips because it has a large number of DC-AC inverters, transformers, and converters, which lead to an increase in IGBTs, MOSFETs, diodes, etc., in the vehicle.
Automotive Parts VS Automotive Chips
Automotive components are automotive-grade electronic components used in automotive and vehicle electronic systems. Automotive components include passive and active automotive components.
Automotive chips, also known as ICs, are automotive integrated circuits with high-density circuits or passive components mounted on silicon wafers, belonging to the category of active components.
What does automotive grade mean for electronic components and chips?
Electronic manufacturing is divided into four grades: defense/aerospace > automotive > industrial > commercial electronics. If components, chips, and PCBs are automotive grade, their manufacturing level is quite high.
For electronic components and chips, automotive grade means:
High standards
Automotive-grade passive components should meet AEC Q200, ASILI/ISO 26262 Class B, and IATF 16949 standards.
Automotive-grade active components (including automotive chips) should meet AEC Q100, ASILI/ISO 26262 Class B, and IATF 16949 standards.
Long service life
Automobiles and vehicles are durable goods, and their service life is usually designed for 15 years or about 200,000 kilometers.
The lifespan of automotive components and chips will also be shortened.
Wide operating temperature range
The operating temperature range of commercial electronic products is 0℃ to 70℃, which is higher than that of commercial electronic parts.
For example, the operating temperature range of components and chips inside and around the engine is -40℃ to 150℃, and the operating temperature range of components inside and around the passenger compartment is -40℃ to 85℃.
Excellent ability to resist harsh environments
During driving, automotive components and chips operate in harsh environments such as vibration, dust, high temperature, harmful gases, humidity, and impact. Therefore, automotive electronics need to have a high ability to resist these harsh factors.
Quality consistency
Automobile manufacturing is mass production, and the quality consistency of automobile hardware is related to driving safety. The quality of automotive components must be highly consistent so that automakers can ensure the quality consistency of automotive systems and vehicles. Therefore, the requirements for automotive components and chips are in units of PPM (parts per million).
How many automotive chips does a car need?
In recent years, the shortage of automotive chips has led to discussions about the supply and demand of automotive chips. How many automotive chips are needed to produce a car?
A traditional car needs 500 to 600 automotive chips.
An electric car needs about 2000 automotive chips because it has a large number of DC-AC inverters, transformers, and converters, which increase the number of IGBTs, MOSFETs, and diodes in the car.
According to surveys, the number of automotive chips required to manufacture a car in 2021 will reach 1000+.
However, the supply of automotive components and chips cannot yet meet the growing demand, which is also the reason for the frequent delays in new car deliveries worldwide.
Which automotive chips are used in automobiles/vehicles?
Automotive chips make cars and vehicles increasingly intelligent. There are three types of automotive chips:
Microcontroller Unit (MCU). MCUs are used in electrical control systems, engines, fuel systems, infotainment systems, powertrains, autonomous driving systems, etc.
Automotive power chips. Mainly used in power control systems, lighting systems, fuel systems, etc.
Automotive sensor chips. Automotive sensors such as tire pressure sensors, water temperature sensors, and electronic throttle pedal position sensors are all developed and operated based on chips.
