In the automotive market, the increase in the amount of new cars and the increase in the number of power management ICs in each new car are driving the strong demand. According to MarketsandMarkets, the number of new cars increases every year, e.g. from 95 million in 2017 to 104 million in 2021. In each of the new cars, the total power management/analog content grows as well, estimated to be from $63 per car to $98 per car between the years 2017 and 2022. These two estimations are reflected in a total automotive power management market compound annual growth rate of approximately 10 percent, $5.8 billion to $10.3 billion between 2016 and 2022.
The increase in the number of chips within a car drives power management ICs to follow with cost-effective solutions as in the mobile market. Today we see more and more companies integrating multiple secondary DC-DC converters into a single PMIC with multiple outputs. Using 65nm BCD technology, the PMIC can include all the needed voltage levels below 5V to support complicated ECUs such as for LiDAR and cameras. A general description of an electric unit in a car shows the secondary PMIC serving all the digital, memories and sensors operating with variety of voltages such as 5V, 3.3V, 1.8V, and sub 1V.
In summary, the 65nm BCD process provides broad design options to IC designers. For example, the option to have more integration of power and digital following multiple trends such as the increased micro motors market, smarter power and higher currents.
