Gate drivers for MOS, GaN and SiC*

Heyday gate drivers are built on proven CMOS silicon technology and can drive MOSFETS as well as the new wide bandgap GaN and SiC FETs.

  • Drive any FET to new unparalleled performance levels.

Our gate drivers come with the breakthrough patented power-thru technology:

  • No more bootstrap components nor isolated supplies required: the Heyday gate drivers do ALL the magic in ONE single integrated package

The benefits of the power-thru technology are substantials.

Innovation based on experience

The Heyday team has leveraged many 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®.

A single 2.6mm high LGA package now delivers isolated gate drive and energy at high speeds to your GaN and MOS FETs.  This enables improvements in efficiency, BOM count, module size, reliability and cost. Great news for all power module designers!

Reliable by design


In its product development processes Heyday uses:

  • standard CMOS technology
  • fabless company => our microchips are fabricated by  well-known players
  • assembly by established packaging company
  • extensive testing in-house, by our pilot clients and by renowned test companies
  • second-source available
