This article is a technical document of Allegro’s Hall effect sensor integrated circuits, how these devices were built, and how Allegro use the Hall effect principle to develop these devices. It ...

Early in the study of electronics we are introduced to magnetism. The lines of force can be demonstrated by iron filings on a sheet of paper with a magnet underneath. In school science class, we made ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...
