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 ...

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 ...

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 ...

Allegro Microsystems has introduced isolated differential current sensor ICs based on the Hall effect. Accuracy is typically +/-1% from 25 to 125°C, and +/-3% from -40 to +25°C. Both the ACS724KMA ...

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 ...

Current sensing with 1MHz bandwidth and 1.2mΩ insertion resistance is claimed by Allegro MicroSystems for its latest Hall-based sensor. Response time for the ACS730, as it is to be called, is 210ns.

The battery packs in electric vehicles (EVs) are only as safe and effective as the battery-management system (BMS) watching over it. The BMS plays a pivotal role in the EV, monitoring the voltages in ...
