3. Current Sensor Companies - Asahi Kasei Corporation (Japan) and Infineon Technologies AG (Germany) are the Key Players

The current sensor market was valued at USD 2.8 billion in 2023 and is projected to reach USD 4.7 billion by 2028, growing at a CAGR of 10.4% during the forecast period from 2023 to 2028. Growing use of battery-powered systems increasing focus on renewable energy, high adoption of Hall-effect current sensors, and increasing demand in the consumer electronics industry are some of the key drivers driving the growth of the current sensor market.

Some prominent current sensor industry players have predominantly used acquisition and partnership tactics to strengthen their market position.

• In August 2023, Allegro MicroSystems, Inc. (US) acquired Crocus Technology (US), a privately held company and one of the leaders in advanced tunnel magnetoresistance (TMR) sensor technology that brought unique technology and products well suited to serve high-growth applications in e-Mobility, clean energy, and automation, through a definitive agreement.
• In May 2023, Infineon Technologies AG (Germany) acquired Swedish startup Imagimob (Sweden) to boost its TinyML edge AI capabilities on its microcontrollers and sensors. Imagimob’s platform enables a wide range of use cases in embedded designs, from audio event detection, voice control, predictive maintenance, gesture recognition, and signal classification to material detection.

Asahi Kasei Corporation (Japan) and Infineon Technologies AG (Germany) are among the top 5 players in the current sensor market.

Asahi Kasei Corporation

Asahi Kasei Corporation is a Japanese multinational holding company that provides monitoring, planning, and strategic management to its subsidiaries and affiliates. It operates through four business segments, namely, Materials, Homes, Health Care, and Others.

The company operates in the current sensor market through its wholly owned subsidiary Asahi Kasei Microdevices (AKM), which provides various advanced sensing devices based on compound semiconductor technology and sophisticated IC products featuring analog/digital mixed-signal technology integrated circuits (ICs). It has expertise in designing and manufacturing high-performance analog and digital ICs. The subsidiary was earlier known as Asahi Kasei e-Materials and was changed to Asahi Kasei Microdevices Corporation in 2009.

AKM has developed advanced current sensors called Currentier, which utilize high-sensitivity compound semiconductor technology. This technology has been cultivated through the company's Hall elements, in combination with their advanced package design and analog circuit design technologies. Currentier is a magnetic open-type current sensor that features a built-in high-sensitivity Hall element. These sensors are capable of quickly and accurately detecting both DC and AC currents, despite their small size. Additionally, they generate less heat and provide high isolation.

AKM has subsidiaries and affiliates in the US, Germany, South Korea, China, Japan, and Taiwan. Some of its key subsidiaries are AKM Technology Corporation (Japan), Asahi Kasei Microdevices (Shanghai) Co., Ltd. (China), Asahi Kasei Microdevices Korea Corporation (South Korea), AKM Semiconductor, Inc. (US), Asahi Kasei Microdevices Europe GmbH (Germany), and SenseAir AB (Sweden).

Infineon Technologies AG

Infineon Technologies AG designs, develops, manufactures, and markets semiconductor and microelectronics solutions.  It offers power modules, sensors, wireless control systems, automotive and industrial transceivers, small signal transistors and diodes, power delivery controllers, etc.

The company was established in 1999 after Siemens AG, its parent company, spun off its semiconductors business. The company is engaged in the development, production, and marketing of a wide range of semiconductor solutions for communication, industrial, automotive, consumer electronics, and security solutions applications.

The company operates through five business segments, namely, Power and sensor Systems,  Automotive, Industrial Power Control, Connected Secure Systems, and Other Operating Segments. The company offers its products related to the current sensor market through the Power & Sensor Systems segment, which provides design, development, manufacture, and marketing of semiconductors for energy-efficient power supplies as well as for mobile devices and mobile phone network infrastructures.

The company's Power & Sensor Systems segment offers products related to the current sensor market. The segment engages in the design, development, manufacturing, and marketing of semiconductors that are used in energy-efficient power supplies, as well as in mobile devices and mobile phone network infrastructures.

The company has a strong presence in North America, Europe, Asia Pacific, and South America. It has production facilities in various countries, including the US, Germany, Hungary, Indonesia, China, Malaysia, South Korea, and Singapore. It has 60 research and development centers and 19 manufacturing locations across 16 countries worldwide.

Some of the key subsidiaries of Infineon Technologies are Infineon Technologies France S.A.S. (France), Infineon Technologies India Pvt. Ltd. (India), Infineon Technologies Asia Pacific Pte. Ltd. (Thailand), Infineon Technologies China Co. Ltd. (China), and Infineon Technologies (Malaysia).
