Cross chip CC6920SO-20A

The CC6920 device is a high-performance Hall-effect current sensor that can measure DC or AC current more efficiently, and has the advantages of high accuracy, excellent linearity and temperature stability in industrial, consumer, and communication equipment. The CC6920 device consists of a high-precision, low-noise linear Hall integrated circuit and a low-resistance main current conductor. Internal copper conductor’s resistance is typical 0.9mΩ, which provides much less power loss than the universal resistor sampling method. Otherwise, its internal inherent insulation provides 424VRMS basic working isolation voltage and 3500VRMS insulation withstand voltage between the input current path and the secondary circuit. The sensor adopts linear Hall sensor temperature compensation technology, which has high temperature stability characteristics. Zero current output voltage is 0.5VCC.
