Introduction

The CC6926 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 CC6926 device consists of a high-precision, low-noise linear Hall integrated circuit and a low-resistance main current conductor. Ultra-low impedance conductor of 30uΩ leads minimize power loss and heat dissipation. Otherwise, its internal inherent insulation provides 5000V_RMS (AC) 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 CC6926 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 CC6926 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. Reference voltage (VREF) allows differential measurements as well as a reference voltage (VOC) for setting overcurrent fault thresholds CC6926 is available in TO263-7 package. It’s operating ambient temperature range is -40~125℃. Comply with RoHS requirements.
