Overview The CC6905 is a high-performance Hall effect current sensor that can more effectively measure DC or AC current. It features high accuracy, good linearity, and temperature stability, and is widely used in industrial, consumer, and communication equipment. The CC6905 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 0.5mΩ conductor, and the magnetic field it generates induces a corresponding electrical signal on the Hall circuit. After internal signal processing, a voltage signal is finally output. The low-impedance conductor minimizes power loss and heat dissipation. The CC6905 is manufactured using an advanced BiCMOS process and includes a differential Hall sensor, chopper amplifier, variable gain amplifier, output polarity/sensitivity/offset, oscillator, filter, zero-point reference output, overcurrent output, and amplifier buffer output, etc. The sensor uses linear Hall sensor temperature compensation technology and has high temperature stability characteristics. The integrated differential common-mode rejection circuit in the CC6905 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 not affected by external pressure and chip packaging stress. The CC6905 is available in SOP8 and QFN-3×3 packages, with an operating temperature range of -40 to +125°C and is RoHS compliant.
