Introduction

The CC6900 is a high-performance linear current sensor with single-ended output, offering an efficient solution for AC or DC current sensing, and is widely used in industrial, consumer, and communication equipment. The device integrates a high-precision, low-noise linear Hall circuit and a low-impedance primary current conductor. When the sensed current flows through the primary conductor, the resulting magnetic field induces a corresponding electrical signal in the Hall circuit. This signal is processed by the conditioning circuitry and converted to a voltage output, making the product easy to use. The linear Hall circuit is fabricated using an advanced BiCMOS process and incorporates a high-sensitivity Hall sensor, Hall signal preamplifier, high-precision Hall temperature compensation unit, oscillator, dynamic offset cancellation circuit, and amplifier output stage. In the absence of a magnetic field, the quiescent output is 50% VCC. At a supply voltage of 5V, the OUT pin voltage varies linearly with the magnetic field over a range of 0.5~4.5V, with a linearity of up to 0.4%. The integrated dynamic offset cancellation circuit ensures that the chip's sensitivity is unaffected by external stress and package stress. The CC6900 is available in an SOP8 package and operates over a temperature range of -40~125℃.
