Monolithic Power Systems MCS1802
The MCS1802 is a linear Hall-effect current sensor for AC or DC current sensing. The Hall array is differential, which cancels out any stray magnetic field. This current generates a magnetic field that is sensed at two different points by the integrated Hall-effect transducers.| Part No. | MCS1802 |

DESCRIPTION
A primary conductor with a low resistance allows current to flow close to the IC, which contains high-accuracy Hall-effect sensors. The magnetic field difference between these two points is then converted into a voltage that is proportional to the applied current. A spinning current technique is used for a low and stable offset. The galvanic isolation between the pins of the primary conductive path and the sensor leads allows the MCS1802 to replace opto-isolators or other isolation devices. The MCS1802 requires a minimal number of readily available, standard external components. The device’s small footprint saves board area and makes it well-suited for space-constrained applications. The MCS1802 is available in an SOIC-8 package.FEATURES
