Every part of the car needs a PMIC, whether it's domain control or an MCU. The analog chip to which PMIC belongs has developed rapidly over the past 20 years, and electric vehicles will be the growth driver in the future. It is expected that by 2026, PMIC will account for 30% of the automotive market.

According to the definition in the "Product Classification 2021" published by the World Semiconductor Trade Statistics Organization (WSTS) at the end of 2020, a power management chip refers to a device that converts a voltage source into a device that can be used by other integrated circuits and controls the output voltage capability. . This includes DC/DC, AC/DC, etc. Some power management chips designed for specific end applications should be classified as special application analog chips. The categories in PMIC are linear regulators, switching regulators, voltage references, BMS, etc.

At the moment of intelligence and automation of automobiles, many PMICs are used in various parts, such as intelligent cockpit, automatic driving, body control, domain control, car lights, BMS management system, etc. Not only does each MCU need PMIC power supply, but each ECU has different types of PMICs.

According to market research firm RESEARCH AND MARKETS, global PMIC sales will reach US$37.7 billion in 2021 and are expected to reach US$55 billion by 2028, with a compound annual growth rate of 5.5%. In addition, according to the report of Tianfeng Securities, the vehicle field has the largest growth in power ICs, with a compound annual growth rate of 9.0%. Electrification and autonomous driving will be the driving force, especially electric vehicles, which Yole expects to account for 30% of the automotive market by 2026, and PMIC will be driven by growth. In addition, Yole expects that by 2026, all passenger cars and 80% of small commercial vehicles will be equipped with at least Level 1 ADAS, which also increases the demand for multi-channel PMICs. Looking back at the trend from January 2002 to November 2021, IHS data shows that the demand for analog chips belonging to PMICs is increasing, while the growth of MCUs is relatively slow.
