Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.

Featuring DC to 5-MHz bandwidth, Allegro MicroSystems' galvanically isolated, high-accuracy magnetic current-sensor IC with zero current reference (ACS37030), and overcurrent fault with internal pull ...

To sense high dc currents, designers typically use shunt resistors or Hall-Effect-based current sensors. But shunt resistors are plagued by Joule (I2R) losses and the need to open the circuit where ...

Alps has developed a range of precision current sensors designed for the fine control of motor operation to optimise power consumption. Current sensors generally employ one of two ...

This application note provides techniques and background information about how a low cost, contact less current sensor can be built with the MLX91206. The sensor has no upper limit to the level of ...
