The automotive industry continues to push the boundaries of technology with connected and electric vehicles (EVs). To meet this growing demand, semiconductor manufacturers Rohm, Toshiba, and Nexperia have introduced new integrated circuits (ICs) designed to enhance automotive applications with compact, power-efficient solutions.
Rohm’s latest offering includes a new series of N-channel MOSFETs with voltage ratings of 40 V, 60 V, and 100 V. These MOSFETs target critical automotive applications such as motors for doors, seats, windows, infotainment, and advanced driver assistance systems (ADAS). With three compact package types, including the DFN2020Y7LSAA, these MOSFETs reduce power loss and heat generation, thanks to their innovative split-gate structure.

Nexperia has introduced its NXF650x-Q100 series of transformer drivers, designed for EVs and HEVs. These drivers offer 6 W power delivery and feature low-EMI and low-noise designs, making them ideal for applications such as battery management systems (BMS), DC-DC converters, and motor control. With protection features like thermal shutdown and over-current protection, these drivers ensure safety in critical EV environments.
As the automotive sector continues to evolve, these new ICs represent significant advancements in power efficiency, safety, and reliability.
