The CC6924 is a high-performance Hall effect current sensor that can more effectively measure DC or AC current. It features high accuracy, excellent linearity, and temperature stability, making it widely used in industrial, consumer, and communication equipment. The CC6924 consists of a high-precision, low-noise linear Hall integrated circuit and a low-impedance main current conductor. The input current flows through an internal 0.3mΩ conductor, generating a magnetic field that induces a corresponding electrical signal on the Hall circuit. This signal is then processed by an 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 inherent insulation provides a 5000VRMS insulation voltage between the input current path and the secondary circuit. The chip is manufactured using an advanced BiCMOS process and includes a differential Hall sensor, chopper amplifier, variable gain amplifier, output polarity/sensitivity/offset/common-mode rejection interface, oscillator, filter, zero-point reference output, current output, and amplifier buffer output, etc. The sensor uses linear Hall sensor temperature compensation technology, exhibiting high temperature stability. The integrated differential common-mode rejection circuit in the CC6924 allows the chip output to be unaffected by external interfering magnetic signals; the integrated dynamic offset elimination circuit ensures that the chip's sensitivity is unaffected by external pressure and chip packaging stress. The CC6924 is available in a SOP16W package, has an operating temperature range of -40 to +125°C, and complies with RoHS regulations.
