MCS1805GS-340-B-P

MCS1805GS-340-B-P is a linear hall-effect current sensor IC for AC or DC current sensing. The differential hall array cancels out any stray magnetic field. The primary conductor’s low resistance allows large currents to flow within close proximity to integrated circuit, which contains high-accuracy hall sensors. This current generates a magnetic field, which is sensed at two different points by integrated hall transducers. The magnetic field difference between these two points is then converted into a voltage that is proportional to applied current. A spinning current technique is used for a low, stable offset. Galvanic isolation between pins of primary conductive path and the sensor leads allow the MCS1805 to replace optoisolators or other isolation devices. It integrates fast OCD which makes it simple to monitor system for OC events. Applications include motor control, automotive systems, load detection and management, switch-mode power supplies and overcurrent fault protection.
