Introduction

CC6926 is a high-performance Hall-effect current sensor capable of effectively measuring DC or AC current, featuring high accuracy, excellent linearity, and good temperature stability. It is widely used in industrial, consumer, and communications equipment. The CC6926 integrates a high-precision, low-noise linear Hall circuit and an ultra-low-impedance primary current conductor. The 30μΩ ultra-low-impedance conductor minimizes power loss and heat dissipation. The inherent internal isolation between the input current path and the secondary circuit provides 5000VRMS (AC) isolation voltage withstand. The sensor employs linear Hall sensor temperature compensation technology for superior temperature stability. The internally integrated differential common-mode rejection circuit prevents the chip output from being affected by external interference magnetic signals; the integrated dynamic offset cancellation circuit ensures that the chip sensitivity is unaffected by external stress and package stress. The CC6926 features an open-drain fast fault monitoring function, making it highly suitable for overcurrent fault detection. The reference voltage (VREF) allows differential measurements, and the device reference voltage (VOC) is used for setting the overcurrent fault threshold. The CC6926 is available in a TO263-7 package, operates over a temperature range of -40 to +125°C, and complies with RoHS requirements.
