This new component offers full isolation (no optocouplers required) and high sensitivity (from 20 mV to 200 mV per Amp of primary current) with no insertion losses. It is mounted directly onto a printed circuit board as an SMD device, reducing manufacturing cost.
Minisen integrates, within one mixed signal ASIC, Hall-effect sensors with a magnetic concentrator to allow direct current measurement without the need for an additional magnetic core. The non-contact measurement enables an almost unlimited current level as it eliminates the need for current to flow through the device. The only limiting factor is the thermal capacities of the primary conductor. The current can be carried either by a track (or tracks) located on a PCB underneath the Minisens, or by a cable or bus bar under or above the IC. The unlimited design possibilities for the primary conductor allow current measurement up to 70A or even higher.
