Webinar
with our Sr Applications Engineers
"Heyday Solves Key Automotive Electrification Design Challenges"
During this webinar we review the main technical challenges with power conversion in the automotive industry and outline the business consequences of these challenges.
We show how the OBC, Inverter, DC-DC and PFC can be impacted by these challenges and explain how Heyday solves these technical and business challenges...
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 feature our patented Power-Thru™ technology:
-
No more bootstrap components or isolated supplies required: the Heyday gate drivers do ALL the magic in ONE single integrated package
The benefits of the Power-Thru™ technology are substantial.

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 180nm CMOS technology
- Tier 1 dual-sourced Fabs
- Industry leading packaging vendors
- Rigorous development an qualification processes
- Second-source strategies
