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 ...

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 ...

Members can download this article in PDF format. High-voltage systems including electric vehicles, industrial robots, communications infrastructure equipment, and renewable-energy installations often ...

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 ...

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

Hall effect sensors are everywhere right now. Keyboards, game controllers, and DIY kits use them for more precise inputs. But with any newly popular device, it can be easy to immediately jump onto the ...

Bipolar Hall-effect sensors are used in BLDC motors to detect the position of the rotating magnet. In this example, an eight-pole motor with a three-phase winding uses three bipolar latching ...

Allegro MicroSystems’ ACS758 Hall effect current sensor range from Solid State Supplies features leading noise performance and ultra-low power loss. The high current devices incorporate Allegro’s ...
