Our Innovations

At Allegro MicroSystems, innovation with purpose is in everything we do. We were first to market with industry-changing technologies such as chopper stabilization, and were the first to commercialize ion implantation, 1MHz current sensor surface mount ICs, and more. Today we’re moving technology—and the world—toward a safer, more sustainable future, investing in new technologies for advanced driver-assistance systems, electric vehicles, and green energy solutions.

Here are just a few of the ways we’ve been helping customers around the world innovate with purpose since 1990.
