Introduction

CC6902 is a high-performance single-ended output linear current sensor that provides an efficient solution for AC or DC current sensing, 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 sampled current flows through the conductor, the resulting magnetic field induces a corresponding electrical signal in the Hall circuit, which is then processed by the signal conditioning circuitry to produce a voltage output, simplifying the application workflow. The linear Hall circuit is fabricated using advanced BiCMOS process technology, incorporating 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. With a 5V supply voltage, the OUT pin voltage varies linearly with the magnetic field over a range of 0.5~4.5V, with linearity up to 0.4%. The integrated dynamic offset cancellation circuit ensures that device sensitivity is unaffected by external mechanical stress and package stress. CC6902 is available in an SOP8 package with an operating temperature range of -40~125℃.
