Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

In February 2026, Allegro MicroSystems introduced the ACS37017 Hall-effect current sensor, completing an expanded portfolio targeting speed, power density, and accuracy for high-voltage applications ...

Allegro MicroSystems is introducing the ACS37017, a Hall effect current sensor targeting power converters, EVs, industrial motor control and clean energy systems.

This application note introduces Hall Effect linear current sensor integrated circuits that are capable of enabling high bandwidth sensing in hybrid electric vehicles and other high current sensing ...

The newest current sensor family from Allegro MicroSystems, Inc., the ACS704, is the first SOIC8-packaged Hall-effect current sensor with the current path integrated into the package for greater ...

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 ...

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 ...

The ACS37017 from Allegro MicroSystems is a Hall-effect current sensor designed for high-voltage power conversion systems in ...

Two similar families of precision, analog-output current sensors use the Hall effect to measure tens of amps with low drift and high linearity while providing 3-kVrms galvanic isolation. Current ...

Texas Instruments has picked the Hall effect for its latest isolated current sensor, and claims 50ppm/°C drift over temperature and ±0.5% drift over lifetime. Aimed at electric vehicle chargers and ...

While TMR works differently, it's a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet ...

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 ...
