SC810 是上海兴工微电子(Senko Micro)开发的基于开环霍尔原理的芯片式电流传感器,可用于交流或直流电流测量,应用于工业,商业和通讯系统。芯片内部由一块精密的低失调线性霍尔电路和与电路距离相当近的铜导体电流路径构成。当路径中注入交流或直流电流时,电路中的霍尔元件对电流产生的磁场进行感应,经过信号处理后输出与电流呈线性关系的电压信号。原边导体的引脚(从1,2到3,4)在电气上与副边信号引脚(从5到8)实现了隔离,这使得SC810可以应用于需要电气隔离的应用场合,替代线性光耦和其他隔离器件。 The Senko Micro’s SC810 provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. The device package allows for easy implementation by the customer. The device consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage. A precise, proportional voltage is provided by the low-offset, chopper-stabilized Linear Hall IC, which is programmed for accuracy after packaging. The terminals of the conductive path (from pin1 and 2 to pin 3 and 4) are electrically isolated from the signal leads (pins 5 through 8). This allows the SC810 to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques.
