Power-Thru Isolation technology
Allegro 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.
Our know-how, key intellectual property and patent portfolio enable the silicon smarts that deliver the capability to make this isolated technology.
