Hall-Effect based Current Sensor With Over-Current-Detection: MCS1823
Cancelling Stray Magnetic Fields
The MCS1823 from MPS is a linear Hall-effect current sensor IC for AC or DC current sensing. The Hall array is differential to cancel out any stray magnetic field.
Magnetic Field Sensed at Two Different Points
A low-resistance (0.6mΩ) primary conductor allows a large current to flow within close proximity to the integrated circuit containing high-accuracy Hall sensors. This current generates a magnetic field which is sensed at two different points by the integrated Hall 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 MCS1823 implements over-current detection (OCD) to easily monitor the system for over-current faults.
The small footprint of the sensor saves board area and makes it well-suited for space-constrained applications. The MCS1823 is available in an ultra-small QFN-12 (3x3mm) package.
