What Heyday Integrated Circuits does
Heyday Integrated Circuits is a private semiconductor company founded in 2014 and headquartered in Grasse, France, focused on designing and selling isolated gate drivers for the power electronics market. The company operates with a micro-team of 1-10 employees and targets the wide-bandgap semiconductor ecosystem, where isolated gate drivers are required to control GaN and SiC FETs in high-power conversion applications spanning electric vehicles, renewable energy, and industrial drives. The business model is built on semiconductor chip design and IP, with revenue mechanics that would be component sales to power electronics system designers, though no pricing, distribution channel, customer count, or contract terms are disclosed in the available data.
Capitalization is sparse: the only recorded funding event is a 2020-08-06 round of approximately $2,894,949 from the European Innovation Council, with no subsequent rounds, acquisitions, partnerships, leadership hires, or product launches documented. The input dataset does not contain any management team information, customer wins, geographic footprint beyond the Grasse headquarters, or independent third-party validation of the company's technology. A material data caveat applies: the bulk of product-level technical content in the source corpus (Power-Thru technology, AHV85110/AHV85111 gate drivers, wide-bandgap application notes) is attributable to a different entity (Allegro MicroSystems) rather than to Heyday IC, so specific product specifications for Heyday IC cannot be substantiated from this input and have not been asserted in this analysis.

Heyday Integrated Circuits competitors and assessment
Company assessmentDirect peers
- Allegro MicroSystems: Allegro is the direct originator of the Power-Thru isolated gate driver platform (AHV85110/85111) referenced in Heyday's data. It is a pure-play analog/power-sensor IC company with established SiC/GaN driver products, making it the closest direct competitor and likely the upstream IP owner or licensor.
- Silicon Labs: Silicon Labs sells isolated gate drivers (Si827x family) targeting SiC and GaN FETs in industrial and renewable energy applications. It is a direct peer in the isolated gate driver IC market with comparable product architecture and customer base.
Broad incumbents
- Texas Instruments: TI offers a broad portfolio of isolated gate drivers (e.g., UCC217xx family) for IGBT, SiC, and GaN applications, supported by a massive analog sales channel and extensive reference designs. It competes broadly with Heyday across all isolated driver sockets.
- Infineon Technologies: Infineon is a leading supplier of SiC power devices and EiceDRIVER isolated gate driver ICs. As a broad-line power semiconductor incumbent with strong automotive/industrial presence, it is a key competitor for any WBG-focused driver startup.
- STMicroelectronics: STMicroelectronics produces STGAP isolated gate drivers for SiC and GaN and bundles them with its own SiC MOSFET portfolio. It is a major European-headquartered competitor directly relevant to Heyday's French/EU positioning.
- ON Semiconductor (onsemi): Onsemi offers isolated gate drivers (NCP/NCV series) for SiC and industrial applications, paired with its own SiC discrete portfolio. It is a broad-line analog/power incumbent competing in the same end sockets.
- Analog Devices: Analog Devices (including former Maxim) sells isolated gate drivers (MAX227xx, ADuM4135) targeting high-voltage SiC/GaN applications. As a broad-line high-performance analog incumbent, it competes for premium isolated driver design wins.
- Monolithic Power Systems: MPS offers a growing portfolio of gate drivers and power management ICs serving industrial, computing, and automotive markets. As a broad-line analog/power competitor, it is comparable in business model and end-customer profile.
Emerging players
- Navitas Semiconductor: Navitas is a GaN power IC company integrating gate drive functionality into its GaNFast power ICs. It represents an emerging 'drive-in-the-package' approach that could either complement or threaten discrete isolated driver suppliers like Heyday.
- Power Integrations: Power Integrations sells SCALE gate driver ICs and InnoSwitch power supply ICs that integrate high-voltage switches with drivers. It is an emerging/adjacent peer in the integrated-power-and-drive architectural space relevant to Heyday's integration approach.
