Allegro has been driving innovation in the current sensor industry for nearly 20 years, with a history of first-to-market products that give our customers a competitive edge. Our advanced ICs help you achieve higher efficiency and power density in your designs. Our fully integrated solutions make design-in easy.
We're leading the market in main traction motor and auxiliary inverters for electric vehicles, and OEMs trust Allegro for applications like DC to DC converters and on-board chargers. We also shine at high voltage with industry leading isolation ratings of up to 1100Vrms—ideal for residential and industrial solar inverter applications.
Allegro offers a unique solution for current sensing through the development of proprietary packaging that employs flip-chip technology. This technology generates excellent magnetic coupling in a core-less package design and provides up to 4800 VRMS galvanic isolation.
Our high current sensor IC packages are fully integrated solutions that also provide high accuracy and reliability. These sensors are automotive-grade devices that can take the heat and deliver highly accurate open-loop current sensing in the harshest applications environments.
