Allegro to acquire Heyday Integrated Circuits

Motion control ICs and sensor maker Allegro MicroSystems to acquire Heyday Integrated Circuits by paying $19 million. Heyday is a specialist in making compact fully-integrated isolated gate drivers for power switching FETs. Heyday' gate drivers are built on CMOS silicon technology and can drive MOSFETs as well as the new wide bandgap GaN and SiC FETs. Allegro says Heyday acquisition will complement its existing solutions for energy efficiency, including its market-leading current sensor solutions. Additionally, it is expected to significantly expand Allegro’s addressable market for electric vehicles (xEV), solar inverters, datacenter and 5G power supplies, and broad-market industrial applications. Quoting industry analysts and internal estimates, Allegro sees these advanced gate drive solutions give it a new access to an estimated $2.7 billion high-growth serviceable available market, increasing Allegro’s content opportunity in green energy applications such as xEV on-board chargers and solar and traction inverters. “With high-powered GaN and SiC wide bandgap systems expected to grow significantly over the next decade, our customers are facing an exponential demand for simplified power management solutions,” said Michael Doogue, Senior Vice President of Technology and Products at Allegro. “High-voltage isolated gate drivers are a fundamental enabling technology for t...
