（具体霍尔开关元件见附录）1.7输入电阻和输出电阻 一般在几Ω到几百Ω，且输入电阻要大于输出电阻1.8外接上拉电阻 一般大于1K Ω。
对一般TTL 电路，由于其高电平电压较低，用于驱动CMOS 电路时，增加上拉电阻，可以提高其高电平的电压。
常用的阻值是4.7k 或10k 。
上拉电阻的是接在1脚电源Vcc 和3脚信号输出Vout 之间。
1.9功能分类 按照霍尔器件的功能可将它们分为: 霍尔线性器件 和 霍尔开关器件 。
前者输出模拟量，后者输出数字量。
都是输出高电平脉冲信号,不同的是开关型相当于到GS 设定值时电平反转；线性的可能是电压逐渐变化,到一定时使后处理电路输出反电平。
一般建议用线性的,开关型常因为温度等原因使得设定值漂移,导致灵敏度下降。

LN4913
■ 产品概述
LN4913 是一款基于混合信号 CMOS 技术的无极性霍 尔开关，这款 IC 采用了先进的斩波稳定技术，因而能够提 供准确而稳定的磁开关点。
在电路设计上，LN4913 提供了一个内嵌的受控时钟机 制来为霍尔器件和模拟信号处理电路提供时钟源，同时这个 受控时钟机制可以发出控制信号使得消耗电流较大的电路周 期性的进入“休眠”模式；同样通过这个机制，芯片被周期 性的“唤醒”并且根据预定好的磁场强度阈值检测外界穿过 霍尔器件磁场强度的大小。如果磁通密度高于“操作点”阈 值或者低于“释放点”阈值，则开漏输出晶体管被驱动并锁 存成与之相对应的状态。而在“休眠”周期中，输出晶体管 被锁定在其先前的状态下。在电池供电应用中，这种设计对 于延长工作寿命提供了最好支持。
霍尔元件简介
2工作原理霍尔元件应用霍尔效应的半导体。
所谓霍尔效应，是指磁场作用于载流金属导体、半导体中的载流子时，产生横向电位差的物理现象。
金属的霍尔效应是1879年被美国物理学家霍尔发现的。
当电流通过金属箔片时，若在垂直于电流的方向施加磁场，则金属箔片两侧面会出现横向电位差。
半导体中的霍尔效应比金属箔片中更为明显，而铁磁金属在居里温度以下将呈现极强的霍尔效应。
利用霍尔效应可以设计制成多种传感器。
霍尔电位差UH的基本关系为:UH=RHIB/d （1）RH=1/nq（金属）（2）式中RH――霍尔系数；n――单位体积内载流子或自由电子的个数；q――电子电量；I――通过的电流；B――垂直于I的磁感应强度；d――导体的厚度。
对于半导体和铁磁金属，霍尔系数表达式和式（2）不同，此处从略。
由于通电导线周围存在磁场，其大小和导线中的电流成正比，故可以利用霍尔元件测量出磁场，就可确定导线电流的大小。
利用这一原理可以设计制成霍尔电流传感器。
其优点是不和被测电路发生电接触，不影响被测电路，不消耗被测电源的功率，特别适合于大电流传感。
若把霍尔元件置于电场强度为E、磁场强度为H的电磁场中，则在该元件中将产生电流I，元件上同时产生的霍尔电位差和电场强度E成正比，如果再测出该电磁场的磁场强度，则电磁场的功率密度瞬时值P可由P=EH确定。
利用这种方法可以构成霍尔功率传感器。
如果把霍尔元件集成的开关按预定位置有规律地布置在物体上，当装在运动物体上的永磁体经过它时，可以从测量电路上测得脉冲信号。
根据脉冲信号列可以传感出该运动物体的位移。
若测出单位时间内发出的脉冲数，则可以确定其运动速度。
[1]3元件特性1、霍尔系数（又称霍尔常数）RH在磁场不太强时，霍尔电势差UH与激励电流I和磁感应强度B的乘积成正比，与霍尔片的厚度δ成反比，即UH =RH*I*B/δ，式中的RH称为霍尔系数，它表示霍尔效应的强弱。
另RH=μ*ρ即霍尔常数等于霍尔片材料的电阻率ρ与电子迁移率μ的乘积。
