The CC6920B is a high-performance Hall-effect current sensor that can more effectively measure DC or AC current, featuring high accuracy, excellent linearity, and temperature stability, widely used in industrial, consumer, and communication equipment. The CC6920B integrates a high-precision, low-noise linear Hall circuit and a low-impedance primary current conductor. Input current flows through the internal 0.9mΩ conductor, and the magnetic field generated induces a corresponding electrical signal on the Hall circuit, which is then processed by the internal circuit to output a voltage signal, making the product easy to use. The low-impedance conductor minimizes power loss and heat dissipation, and the internal intrinsic insulation provides a basic operating isolation voltage of 424VRMS and 3500VRMS isolation withstand voltage between the input current path and the secondary side circuit. The linear Hall circuit is produced using an advanced BiCMOS process and includes a high-sensitivity Hall sensor component, Hall signal pre-amplifier, common-mode magnetic field rejection circuit, temperature compensation unit, oscillator, dynamic offset cancellation circuit, and amplifier output module. In the absence of current, the quiescent output is 50% VCC. Under a power supply voltage of 3.3V, the output can linearly change with the magnetic field between 0.33V and 2.97V, with linearity up to 0.1%. The CC6920B's internally integrated differential common-mode rejection circuit allows the chip output to be unaffected by external interfering magnetic signals; the integrated dynamic offset cancellation circuit ensures that the IC's sensitivity is not affected by external pressure and IC package stress. The CC6920B is available in SOP8 package, operates over a temperature range of -40 to +125°C, and complies with RoHS regulations.
