New 40V MOSFET to control BLDC motors for automotive applications

Given concerns about global climate change and corresponding efforts to reduce carbon emissions, the Electric Vehicle (EV) market is projected to grow significantly. Omdia, a global market research firm, estimates that the global EV market is expected to grow 27% annually between 2022 and 2025. As such, demand for high-efficiency and durable BLDC motors for EVs will increase and Medium Voltage (MV) MOSFETs are essential for BLDC motors to operate efficiently. Magnachip has developed a new 40V MOSFET featuring low RDS(on)* to reduce the conduction loss of automotive BLDC motors and the company began mass production of this new MOSFET in April 2022.  

As reliable automotive semiconductors are critical to vehicle safety, the new 40V MOSFET is fully AEC-Q101 (Automotive Electronics Council-Q101) certified. The first application of this new product is for the Electric Water Pump of a new EV model from a global auto manufacturer. This MOSFET is also suitable for a variety of BLDC applications, such as electric oil pumps, engine cooling fans, electric power steering and battery cooling fans.

Magnachip continues to expand its market share in the automotive semiconductor sector with new products and advanced technology. Further, Magnachip is becoming a stable supplier of power semiconductor products as an integrated device manufacturer amid global supply chain disruptions affecting the automotive semiconductor industry, which is forecast to last through 2023.  

“The market for both electric and internal combustion engines in the automotive sector is more competitive than ever and the demand for high-performance MV MOSFETs is increasing rapidly,” said YJ Kim, CEO of Magnachip. “Accordingly, we are strengthening our presence in global markets and believe the release of this new 40V MOSFET will help us to secure greater market share.”

*RDS(on): On resistance, the resistance value between the drain and the source of MOSFETs during on-state operation
