Overview
MCS1802 3.
3V, Linear Hall-Effect Current Sensor with ±2.
5% Accuracy Over Temperature DESCRIPTION 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.
A primary conductor with a low resistance allows current to flow close to the 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 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.
