Current Sensor ICs

Allegro MicroSystems has been driving innovation in the current sensor industry for more than 20 years, and continue to deliver first-to-market products that allow you to get a competitive edge over your competitors. Allegro offers a line of fully integrated Hall-effect current sensor ICs that provide highly accurate, low noise output voltage signals that are proportional to an applied AC or DC current, sensing even beyond 200 A with Allegro innovative linear ICs.

These current sensor ICs are in high volume production in many industrial applications such as motor control, smart meters, 2-wheelers, robotics, building automation or power tools, and in various places in today’s cars. Allegro also shines at high voltage with industry leading isolation ratings of up to 1100 _VRMS —ideal for residential and industrial solar inverter applications. Additionally, Allegro’s current sensors are also used in many power monitoring applications, such as data centers and server power supplies.

Allegro’s current sensors employ unique advanced IC and packaging techniques that help Design Engineers innovate in their new challenging applications, especially when increased energy efficiency and new operating features are required is required.
