Overcoming the Automotive-Grade IC Shortage
According to statistics from AutoForecast Solutions, the global automobile industry reduced production by 4.5 million new cars in 2022 due to the shortage of chips. It is estimated that production will be reduced by an additional 3 million cars in 2023. What are the reasons for the chip shortage, and how can we deal with it more efficiently? This article will provide some insights.

What are automotive-grade ICs?
Automotive-grade chips are kinds of semiconductors used in vehicle control devices, vehicle-mounted monitoring devices and vehicle-mounted electronic control devices, which are mainly applied in vehicle control modules, in-vehicle infotainment, power transmission integrated control systems, active-safety systems and so on.
Automotive-grade ICs can be divided into functional categories like control/calculation chips (MCUs, CPUs, FPGAs, ASICs, AI chips, etc.), power semiconductors (IGBTs and MOSFETs), sensors (CIS, acceleration sensors, etc.), wireless communication and automotive interface chips and automotive memory.
Automotive grade vs. commercial, industrial grades
Automotive-grade chips require higher reliability, such as wider working temperature range and better working stability, compared with commercial- and industrial-grade chips. The differences between chip grades are mainly determined by complex chip design processes and control of production processes, resulting in differentiation in working temperature ranges, stability and other aspects. Additionally, automotive-grade chips need to pass ISO/TS16949, AEC-Q100 and ISO 26262 certifications, a process that usually takes two to three years to complete.
