The MPS MCS18xx Family
Efficient, Cost-Effective and Available Current Sensors
The members of the MCS18x family are linear Hall-effect current sensors ICs for AC or DC current sensing. The Hall array is differential to cancel out stray magnetic field.
A low-resistance 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. A small footprint enables easy integration into existing designs. With up to 3kVRMS isolation and a wide sensing range from ±5A to ±50A they fit various applications with different current levels and offer an alternative to shunt, transformer or optical isolated solutions while offering enhanced efficiency and smaller form factors.
The MCS18x family is ideal for wide variety of applications like multi-phase inverters, over-current fault protection, motor control, switched-mode power supplies, solar inverters, RF amplifiers, and automotive systems.
Samples available from stock up to two weeks, production quantities < 16 weeks.
