Current Sensor ICs
Allegro MicroSystems, LLC has developed a line of fully integrated Hall-effect current sensor ICs and Hall-effect linear ICs that provide highly accurate, low noise output voltage signals that are proportional to an applied AC or DC current. These current sensor ICs are in high volume production in many applications, including automotive HEV inverters and electronic power steering (EPS) systems, and in industrial and consumer inverters, compressors, and motors. Allegro current sensor ICs are also used in many power monitoring applications, such as computer blade servers and server power supplies.
Allegro’s proprietary fully integrated Hall-effect current sensor ICs employ advanced IC and packaging techniques for sensing current from 5 A to 200 A. For sensing beyond 200 A an Allegro current sensor linear IC can be used. Allegro current sensor ICs allow design engineers to use Hall-effect-based current sensor ICs in new applications where increased energy efficiency or new operating features are required.
Wherever current sensing is needed, an Allegro sensor IC can provide a solution.
