絶縁ゲート ドライバー

GaN FET Isolated Gate Driver Dual Chipset

The AHV85000 and AHV85040 is a dual chipset that offers a flexible isolated gate drive for GaN FETs with the benefits of Power-Thru technology. This simplifies system design, reduces EMI, and supports driving a floating switch in various power applications.
