Magnetic sensing indirectly measures the load current by making use of Ampere’s & Faraday’s laws. They measure the magnetic field produced by a current running through a conductor. Due to the non-invasive measurement technique, this method inherently offers high levels of isolation. TI’s magnetic sensors include fluxgate and hall effect sensors, designed to address position and current sensing.
