                                                                                                  MCS1803 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. A primary conductor with a low resistance allows current to flow close to IC, which contains high-accuracy hall-effect sensors. This current generates a magnetic field that is sensed at two different points by the integrated hall-effect transducers. 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 stable offset. The galvanic isolation between pins of primary conductive path and the sensor leads allows MCS1803 to replace opto-isolators or other isolation devices. It requires a minimal number of readily available, standard external components. MCS1802 is available in SOIC-8 package. Applications include motor control, automotive systems, load detection and management, SMPS and overcurrent fault protection.
