Integrated sensor having a magnetic flux concentrator |
摘要 |
An integrated sensor has a magnetic field sensing element and first and second relatively high magnetically permeable members forming a gap, wherein the magnetic field element is disposed within the gap. The magnetically permeable members provide an increase in the flux experienced by the magnetic field sensing element in response to a magnetic field. The integrated sensor can be used as a current sensor, a proximity detector, or a magnetic field sensor.
