SC820 is a chip type current sensor with wide isolation distance and high current capacity developed by Shanghai Xinggan Microelectronics Co., Ltd. This product adopts wide body sop-16 package form, and achieves current wire impedance as low as 0.6m Ω on the package of 10.3mm * 10.4mm * 2.3mm, so it can be applied to the power system requiring continuous work and measuring up to 65A. The SC820 series of Xinggan 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. SC820 adopts automatic production and processing, which can bring incomparable consistency, high quality and high reliability to customers. The standard package design is very suitable for customers to carry out batch automatic placement production. It is the best solution for photovoltaic inverter, household appliances, charging pile and other applications. Xinggan microelectronics is committed to the research of core chip technology, in order to bring customers the best current detection solutions for the purpose.
