Simplifying and accelerating high-power GaN and SiC system implementation

Allegro MicroSystems, Inc has acquired Heyday Integrated Circuits (Heyday), who specialise in compact, fully integrated isolated gate drivers that enable energy conversion in high-voltage GaN and SiC WBG semiconductor designs.

This acquisition combines Heyday's isolated gate drivers and Allegro's market-leading isolated current sensors to provide some of the smallest high-voltage and high-efficiency power systems. Also, this is expected to increase Allegro's addressable market for xEV, solar inverters, data centres and 5G power supplies, and broad-market industrial applications.

"The demand for simplified power management is increasing across the board, and high-voltage isolated gate drivers are fundamental for enabling technology for the future of high-efficiency power system designs," said Joe Duigan, senior director, Engineering and Business Development. "Together with Allegro's market-leading current sensors and Heyday's isolated gate drivers, we will be able to power the increasingly popular GaN and SiC MOSFET driven systems."

"We're thrilled to welcome Heyday to the Allegro family," said Vijay Mangtani, vice president of Power ICs at Allegro. "This acquisition will greatly accelerate our efforts to deliver a market leading energy-efficient technology platform for high-voltage designs in advanced mobility, clean energy, and motion control solutions."
