Current Sensor ICs

Allegro MicroSystems

With increasing concerns about the global demand for energy and environmental awareness, power electronics applications are under pressure to improve efficiency which necessitates the need for accurate current sensing. These sensors combine basic current measurement in a line of fully integrated Hall-effect current sensor ICs that provide highly accurate analog output voltage signals proportional to the applied current. The sensors can be used in applications that require voltage isolation and operation to 120 KHz bandwidth.
