Using the Hall effect for current measurement is inherently robust, but it can be an even more versatile tool when it comes to position sensing.

A new generation of small Hall-effect-based current sensors simplify the task. Hall-effect devices measure current via the intensity of the magnetic field generated by the current flow.

To measure the hall-effect sensor’s output at higher currents, one must either have a higher current power supply or, more wire wraps inside core of the sensor. This design idea explores the latter ...

You can use a current-shunt or Hall-effect sensor to make such measurements, but recent innovations have given the Hall-effect current sensor an edge up over current shunts in many applications.

Advances in IC technology have led to the Hall-effect sensors and current mirror methods for board-level current measurement and monitoring.

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

The Hall-effect based current sensors are qualified for use in a range of automotive and industrial applications, such as on-board chargers (OBC), DC/DC converters, power supplies, and small electric ...

The major drivers, restraints, opportunities, and challenges for the Hall-Effect current sensor market have been detailed in this report.
