- Abstract:
- This paper introduces a novel magnetic sensor IC for current sensing applications. The magnetic sensing function is based on the combination of the Hall effect devices for DC and low frequency fields, and an inductive coil for high frequency fields. The sensor IC incorporates a horizontal Hall device and a planar coil for the magnetic field perpendicular to the chip surface; and a vertical Hall device that can be combined with an external coil for the magnetic field parallel to the chip surface. The integrated signal processing electronics contains innovative circuits based on the switched capacitors, which combines the Hall and coil signals in a convenient, stable and reproducible way. The new sensor features the frequency bandwidth from DC to 1MHz and the equivalent magnetic field noise 40µTrms.
