Cross chip CC6937S8-5FB005

The CC6937 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 CC6937 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 0.5mΩ which provides much less power loss than the universal resistor sampling method. Otherwise, its internal inherent insulation provides 3750VRMS 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. The differential common-mode suppression circuit integrated in CC6937 can make the chip output unaffected by external interference magnetic signals. The integrated dynamic offset elimination circuit makes the sensitivity of the chip independent of external stress and chip packaging stress.
