Analysis Report on 35 Domestic Power Management Chip Manufacturers

Summary

The AspenCore analyst team carefully selected 35 representative companies from numerous power management chip manufacturers, categorizing them into four major categories: PMIC, wireless charging/fast charging, battery management, and LED drivers. Each company is detailed according to evaluation criteria such as core technologies, key products, main applications, and competitiveness, compiling the “Analysis Report on 35 Domestic Power Management Chip Manufacturers”.

In addition, last year’s “Research Report on 30 Domestic Power Management Manufacturers” included both power management chips and power devices. This year, we have separated power management chips and power devices into two distinct analysis reports. This report specifically focuses on power management, while the report on power semiconductors, titled “Analysis Report on 30 Domestic Power Devices and Third-Generation Semiconductor Manufacturers,” has already been published.

The classification of power management chips and their corresponding functions are shown in the table below:

The downstream application scenarios for power management chips are rich and mainly cover industries such as communications, consumer electronics, automotive, and the Internet of Things. Different applications have different performance requirements for power management chips, with automotive and industrial applications having higher stability and quality requirements; consumer electronics products have relatively lower requirements but are more price-sensitive; the power management chips used in smartphones have high requirements for size, stability, and consistency, creating high technical barriers and supply chain thresholds for smartphone manufacturers.

According to Frost & Sullivan statistics, the market size of China’s power management chips exceeded 80 billion yuan in 2020, accounting for about 35.9% of the global market. It is expected that from 2020 to 2025, the market size of China’s power management chips will grow at a compound annual growth rate of 14.7%, reaching a market size of 23.45 billion US dollars by 2025.

Comprehensive Comparison of Domestic Power Management Chip Listed Companies

Power management chips are general-purpose devices, and their design and manufacturing processes are relatively mature. Therefore, there are many domestic chip manufacturers in this market (similar to the MCU market). The table below compares Yingjixin (the issuer in the table) with five other listed domestic power management chip companies.

Note: 1. The issuer in the table refers to Yingjixin; 2. According to statistics from the China Business Industry Research Institute, the market size of China’s power management chips in 2020 was 78.1 billion yuan. Data Source: Yingjixin Prospectus

In the segmented market of power management, battery management and wireless charging have been rapidly growing application markets in recent years. Below, we will focus on the technical applications and market trends of these two categories.

Battery Management System (BMS)

The Battery Management System (BMS) is a system for managing, controlling, and utilizing battery packs. Its main function is to intelligently manage and maintain each battery cell, preventing overcharging and over-discharging to extend the battery’s lifespan, and monitoring the battery’s working status. BMS can collect, process, and store important information during the operation of the battery pack in real time, exchange information with external devices, and address key issues such as safety, availability, usability, and lifespan in lithium battery systems.

The application fields of BMS include new energy vehicles, communications, renewable energy, and UPS uninterruptible power supplies, among which new energy vehicles are the most common application field for BMS. According to Frost & Sullivan statistics, the global BMS market for new energy vehicles grew from 450 million US dollars in 2016 to 1.42 billion US dollars in 2020, with a compound annual growth rate of 33.3%. Driven by the rapid development of domestic new energy vehicles, the domestic BMS market demand has grown rapidly, with the market size increasing from 1.29 billion yuan in 2016 to 2.63 billion yuan in 2020, with a compound growth rate of 19.5%. It is expected to continue to grow at a rate of 16.6% from 2020 to 2025.

There are not many domestic chip manufacturers capable of developing complete BMS products, but a few battery management chip manufacturers have shown quite good market performance, including Jiewater, Xinzhi Hui, Suzhou Saixin, and Guangdong Saiweiwei. Saimeiwei Electronics, which successfully passed the IPO review on the Sci-Tech Innovation Board, had a revenue of 180 million yuan in 2020 and 160 million yuan in the first half of 2021. Its main products include battery safety chips, battery metering chips, and charging management chips. The company relies on its self-developed battery electrochemical property analysis, extraction, and data modeling technology, as well as the “FastCali” battery power algorithm, to develop battery metering chips that can quickly calculate battery status and internal resistance, accurately provide the state of charge during the battery’s lifecycle, and control errors within 1-3%. It can estimate the state of charge of batteries at different temperatures and different lifecycles with high precision, low power consumption, fast response speed, and strong battery tracking capabilities.

Wireless Charging

Wireless charging is a technology that connects inductive coils at the transmitter (TX) and receiver (RX) ends, driving the inductive coil at the transmitter to generate an alternating magnetic field, and using the inductive coil at the receiver to couple the alternating magnetic field to generate AC power and transmit electrical energy. Wireless charging chips mainly include two categories: receiving-end chips and transmitting-end chips, with applications primarily covering consumer electronics such as smartphones, tablets, smart wearable devices, and wireless chargers.

After 10 years of development, wireless charging has grown from a niche market to a technology widely adopted in the mobile phone, consumer electronics, and automotive markets. According to market analysis firm Strategy Analytics, the cumulative number of mobile phones with wireless charging capabilities exceeded 1 billion units in 2021, along with wireless charging-enabled TWS earphones, with sales of wireless charging transmitters reaching approximately 1.97 million units and sales of Qi-certified wireless charging receiving devices reaching as high as 550 million units. The Asia-Pacific region accounts for about 39%, especially the Chinese consumer market, which has always been a major driver of wireless charging.

There are many domestic wireless charging chip and application solution manufacturers, including Meixinsheng, Nanxin, Yichong Wireless, Yingjixin, Fuda Semiconductor, Xinzou Technology, Zhonghui Chuangzhi, Jinxin Micro, Ruiyuan Semiconductor, Baiyi New Energy, Weipu Innovation, and Beilan Technology. The receiving-end wireless charging chips must be embedded in smartphones and smart terminals, requiring high integration, output power, conversion efficiency, and compatibility parameters, necessitating manufacturers to master key technologies such as efficiency, temperature rise control, and overvoltage protection under high-power wireless transmission of power management chips. Therefore, there are high technical barriers, and domestic chip manufacturers have emerged and achieved a leading position in core technologies, with major manufacturers capable of developing complete high-efficiency receiving-end chips being Meixinsheng and several other chip manufacturers mentioned above.
