Sc813 is a member of Xinggong micro fully integrated Hall current sensor product line. Its main differential output mode is convenient for later stage application. Its ultra wide dynamic detection capability supports customers to detect current range as low as 1a and as high as 30A. Under the condition of insulation and isolation, it can realize the detection of load current. It is suitable to replace other passive or discrete sensor detection schemes such as power resistance, linear optocoupler, transformer, etc. The sc813 series of Xinggong micro is an isolated current detection chip based on the open-loop Hall sensor detection principle. By introducing the current wire at 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 induced by the magnetic sensor of the built-in chip, and then converted into a processable proportional voltage signal. The voltage signal is read and amplified by the built-in high-precision ADC, and the loops such as temperature, noise, hysteresis and nonlinearity are removed with digital calibration technology Environment variable, the final output and measured current value into an ideal ratio of the voltage value, to achieve isolated current measurement. Sc813 adopts fully automatic production and processing, which can bring incomparable consistency, high quality, high reliability and low cost to customers. The standard package design is very suitable for customers to carry out batch automatic placement production. It is the best solution for power devices, current detection, household appliances, power supply, load detection and other applications. Xinggong microelectronics is committed to the research of core chip technology, in order to bring customers the best current detection solutions for the purpose.
