There are several key challenges to driving FET's. This is true whether it is GaN, MOS or SiC.
Heyday Technology has addressed and solved all of these challenges. The Heyday team has turned this technology into a reality resulting in a product line of isolated gate drivers fit for the most challenging designs and applications.
Heyday has leveraged years of experience to develop a unique technology enabling high performance gate drivers. In one single package and across one single internal isolation boundary both the gate drive signal and the drive power are transferred.
We have called it power-thru ®.
The simplicity of the isolation boundary makes it efficient by design. Efficient electrically and physically.
A tiny magnetic based isolation structure enables efficient power transfer across the boundary from low-voltage signal to high-voltage system. This boundary carries not only the gate drive signal information but also all the drive power required to drive the external FET switch. The system designer can now deliver isolated drive to a high-side FET as easily as a low-side FET.
Heyday's know-how, key intellectual property and patent portfolio enable the silicon smarts that deliver the capability to make this isolated technology. The Heyday product line is just starting but is growing fast!
Magnetic isolation has been known for years as an efficient way to transfer energy. But getting the required drive energy and information efficiently through a magnetic component small enough to fit in a semiconductor sized package - that's a new story.
A single isolation boundary is used to transfer both the drive information and the drive energy from a low voltage control circuit to the high-voltage system switch circuit. This single path approach makes for simpler and smaller product package.
Heyday silicon is the enabler which steers the energy and information across a tiny magnetic boundary with amazing efficiency and speed to make outstanding gate drive products. Through novel silicon techniques such as:
Heyday has delivered new isolated gate drivers which have long been sought by power system designers. Heyday's IP rich patent portfolio is growing quickly in this exciting fast growing market space of isolated gate drives.
Heyday has always believed in simplicity regarding the package design. Leave the complexities to the silicon!
Heyday's first products are based on the well-known Land Grid Array, LGA, design. Our small 10 x 7.7 x 2.6 mm LGA device is packed with features, performance and functionality that will enable the best and most efficient power module designs.
