Welcome to the Allegro MicroSystems Alternatives to Shunts for Current Sensing product training module. 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 magnetic current sensor ICs (Hall-Effect and GMR) 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. Additional features such as over-current digital fault outputs and filtering pins are available on several sensors. Sensing currents from 5 A to 2000 A is made possible with Allegro current sensing solutions.
