Cross chip CC6922SG-5FB100-Q1

The CC6922-Q1 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 differential common-mode suppression circuit integrated in CC6922-Q1 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. Another advantage of the CC6922-Q1 is the fast fault monitoring function of the open-drain output, which is ideal for overcurrent fault detection. This feature is flexible in fault detection and greatly simplifies board application layout. The reference voltage (VREF) allows differential measurements and is allowed to be used as a reference voltage (VOC) of setting the overcurrent fault threshold CC6922-Q1 is available in SOP16W package. It’s operating ambient temperature range is -40~125℃. Comply with RoHS requirements. The CC6922-Q1 device is a precision current sensor based on Hall sensor. It has less than 3% full scale error and zero current reference signal output in the whole temperature range, which can realize bidirectional current detection. The input current flows through a wire between isolated input current pins, which has a resistance of 0.3mΩ at room temperature to reduce insertion loss. The magnetic field generated by the input current is sensed by Hall sensor and amplified by precise signal chain. It can be used for AC and DC current measurement with a bandwidth of 250kHz. The measuring current is 65A and 100A. There are 2 kinds of Current sensing range to choose. CC6922-Q1 is optimized for high accuracy and temperature stability, compensating for misalignment and sensitivity over the entire range. The input current of CC6922-Q1 flows through the primary side of the package through |P+ and IP- pins, the current flowing through the chip generates a magnetic field proportional t
