The SC783 series from Vicorv is an isolated current detection chip that operates based on the open-loop Hall sensor detection principle. By introducing the current wire on the high-voltage side into the package, based on the magnetic effect of the current, the proportional magnetic field generated around the measured wire is aggregated by the magnetic core, induced by the built-in chip's magnetic sensor, and converted into a processable proportional voltage signal. This voltage signal is read and amplified by an internal high-precision ADC, combined with digital calibration technology to remove environmental variables such as temperature, noise, hysteresis, nonlinearity, etc., and finally outputs a voltage value that is close to the ideal ratio to the measured current value, achieving isolated current measurement.
SC783 adopts fully automated production and processing, which can bring customers unparalleled consistency, high quality, and high reliability in module technology. This product can be used for AC or DC current measurement and is applied in industrial, commercial, and communication systems such as UPS, charging stations, frequency converters, and white goods.
