Automotive electronic chips are chips used in automobiles, collectively referred to as automotive chips. Automotive chips are mainly divided into three categories, as follows:
1. Functional chip: mainly refers to the processor and controller chip. Cars can run on land without electronic and electrical architecture for information transmission and data processing.
Vehicle control system mainly includes body electronic system, vehicle motion system, power system, infotainment system, automatic driving system and so on.
These systems have many sub-functional items, each sub-functional item behind a controller, the controller will have a function chip inside.
2. Power semiconductor: mainly responsible for power conversion, mostly used in power supplies and interfaces, such as IGBT power chips for electric vehicles, which can be widely used in analog circuits and digital circuits of field-effect transistor MOSFET.
3. Sensor: mainly used for various radar, airbag, tire pressure detection.
Automotive chips, from the application link, can be roughly divided into main control chip, power chip, sensor chip, memory chip, etc., the proportion is about 23%, 22%, 13%, 9%.
