Hyundai Mobis Accelerates In-House Car Semiconductor Production... Establishes Base in Silicon Valley
Hyundai Mobis Begins Mass Production of Automotive Semiconductors
Strengthening In-House Design Capabilities for Internalization
Hyundai Mobis is accelerating the internalization of automotive semiconductors by mass-producing self-designed vehicle semiconductors and establishing a research base in Silicon Valley, USA.
On the 18th, Hyundai Mobis announced that it has completed reliability verification of automotive semiconductors used in electrification, electronic components, and lamps, and has begun mass production. This comes five years after acquiring the semiconductor business from Hyundai Autron in 2020.
The main semiconductors to be mass-produced this year are power integrated chips combining power control functions for electric vehicles and lamp-driving semiconductors. The battery management integrated circuits (ICs), which are already being supplied, are currently under active development for next-generation products. These semiconductors monitor the charging status of electric vehicles and contribute to safety.
Hyundai Mobis has been dedicated to research and development of automotive semiconductors, a core elemental technology leading future mobility. It operates a separate organization called the Semiconductor Business Division and has secured about 300 specialized personnel. This year, it will establish a specialized research base in Silicon Valley, USA, to strengthen collaboration with global semiconductor companies and attract outstanding overseas talent.
Hyundai Mobis’s development direction for automotive semiconductors is broadly divided into power semiconductors and system semiconductors. First, Hyundai Mobis aims to complete the electrification value chain through internalization of power semiconductor design. Power semiconductors are semiconductors that improve the driving range and driving capability of electric vehicles. Currently, Hyundai Mobis is mass-producing 'power modules,' which integrate multiple power semiconductors and add cooling functions as a larger unit.
Hyundai Mobis plans to have the full lineup of electric vehicle drive systems, from power semiconductors, power modules, inverters, motors, to PE systems. Since power semiconductors are key factors determining performance and cost, internalizing them can also enhance the competitiveness of next-generation drive systems.
System semiconductors perform various functions such as power supply, driving, communication, sensing, and networking. As the number of controllers needed to realize autonomous driving and software-defined vehicles (SDV) increases, semiconductors are gaining attention as competitive core components. Hyundai Mobis plans to enhance its independent design capabilities for strategic system semiconductor products and establish a separate ecosystem for other semiconductors to improve supply responsiveness.
