The CC921 product family is an open-loop current sensor module based on the Hall effect principle, which
can be used for AC or DC detection in a wide range of industrial, commercial and communication systems.
Each CC921 consists of a high precision, low noise, low temperature drift linear Hall IC, magnetic core, and built-in current conductor path with low insertion resistance. The applied current flowing through the path of a low-resistance current conductor creates a magnetic field, which the chip converts into a voltage signal output proportional to the input current. Because of the use of magnetic core inside the module, it can effectively suppress the interference of external common mode magnetic field to the module, and improve the accuracy in the magnetic field environment.
