Current Sensor ICs

Current Sensor ICs applications (isolator, current transducer, current sensing, hall effect current sensing, hall effect current sensor, current sensors)

Allegro MicroSystems, LLC has developed a line of fully integrated Hall-effect and GMR current sensors and Hall-effect linear integrated circuits that provide highly accurate, low noise output voltage signals that are proportional to an applied AC or DC current. These 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 and motor control applications.

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 0 A to 50 A and 50 A to 400 A. These integrated solutions provide galvanic isolation (up to 4.8 kV) and extremely low resistance on the primary conductor (≤ 1mΩ) for highly efficient solutions and are available in a variety of surface mount and through-hole packages.  For sensing beyond 200 A, an Allegro linear current sensor 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 Hall-effect or GMR current sensor ICs can provide a solution.
