This application note presents some of the fundamental information about Hall-Effect sensors. It also presents the basics of magnetics, and the added value of programmable sensors and sensor interface ...

Allegro MicroSystems, LLC introduces a new linear, Hall-effect sensor IC specifically designed for applications that require medium accuracy in a very small package. Allegro’s A1304 is a factory ...

Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

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 ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

While most sensors that surround us and make modern technology possible are well-known and understood, magnetic sensors used in magnetometers are often overlooked or misunderstood, even though they’re ...

Current sensing is on a trajectory to intersect with the global high-voltage trend of robust, high-performing systems. Discover the tradeoffs between isolated shunt-based, closed-loop Hall-effect, and ...
