微型霍尔效应传感器最终可以做在集成电路里,用来控制和测量电流。这种集成霍尔效应电流传感器可用于可编程电源和保护电路。霍尔效应应用于电流测量的基本原理早就建立了。霍尔效应传感器是测量导线附近某个固定位置的磁场,由于磁场与导线电流之比是可知的(几何函数),所以可推算出电流大小。尽管这个基本原理简 Micro-Hall effect sensors can eventually be used in integrated circuits to control and measure current. This integrated Hall-effect current sensor can be used for programmable power and protection circuits. The basic principle of Hall effect applied to current measurement has long been established. Hall effect sensors measure the magnetic field at a fixed position near the conductor. Since the ratio of the magnetic field to the conductor current is known (geometric function), the magnitude of the current can be estimated. Despite this basic principle of Jane
