(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。

■ 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

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。

It incorporates advanced chopper-stabilization techniques to provide accurate and stable magnetic switch points.The circuit design provides an internally controlled clocking mechanism to cycle power to the Hall element and analog signal processing circuits. This serves to place the high current-consuming portions of the circuit into a “Sleep” mode. Periodically the device is “Awakened” by this internal logic and the magnetic flux from the Hall element is evaluated against the predefined thresholds. If the flux density is above or below the B OP /B RP thresholds then the output transistor is driven to change states accordingly. While in the “Sleep” cycle the output transistor is latched in its previous state. The design has been optimized for service in applications requiring extended operating lifetime in battery powered systems.The output transistor of the SS239 will be latched on (B OP ) in the presence of a sufficiently strong South or North magnetic field facing the marked side of the package. The output will be latched off (B RP ) in the absence of a magnetic field.Typical Application CircuitSEC's pole-independent sensing technique allows for operation with either a north pole or south pole magnet orientation, enhancing the manufacturability of the device. The state-of-the-art technology provides the same output polarity for either pole face.It is strongly recommended that an external bypass be connected (in close proximity to the Hall sensor) between the supply and ground of the device to reduce both external noise and noise generated by the chopper-stabilization technique. This is especially true due to the relatively high impedance of battery supplies.Internal Timing CircuitPin Definitions and DescriptionsSOT Pin №SIP Pin №Name Type Function1 1 VDD Supply Supply Voltage pin2 3 OUT Output Open Drain Output pinGroundpin3 2 GNDGroundTable 1: Pin definitions and descriptionsAbsolute Maximum RatingsParameter Symbol Value UnitsSupply Voltage (operating) V DD 6 VmASupply Current I DD 5Output Voltage V OUT 6 VOutput Current I OUT 5mA85°CtoOperating Temperature Range T A -40150°CStorage Temperature Range T S -50toESD Sensitivity - 4000 VTable 2: Absolute maximum ratingsExceeding the absolute maximum ratings may cause permanent damage.

在电路设计上,YS4913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。

霍尔效应实验说明书

霍尔效应实验说明书

霍尔效应实验霍尔效应是导电材料中的电流与磁场相互作用而产生电动势的效应。

1879年美国霍普金斯大学研究生霍尔在研究金属导电机构时发现了这种电磁现象,故称霍尔效应。

后来曾有人利用霍尔效应制成测量磁场的磁传感器,但因金属的霍尔效应太弱而未能得到实际应用。

随着半导体材料和制造工艺的发展,人们又利用半导体材料制成霍尔元件,由于它的霍尔效应显著而得到实用和发展,现在广泛用于非电量检测、电动控制、电磁测量和计算装置方面。

在电流体中的霍尔效应也是目前在研究中的“磁流体发电”的理论基础。

近年来,霍尔效应实验不断有新发现。

1980年原西德物理学家冯·克利青(K.Von Klitzing )研究二维电子气系统的输运特性,在低温和强磁场下发现了量子霍尔效应,这是凝聚态物理领域最重要的发现之一。

目前对量子霍尔效应正在进行深入研究,并取得了重要应用,例如用于确定电阻的自然基准,可以极为精确地测量光谱精细结构常数等。

在磁场、磁路等磁现象的研究和应用中,霍尔效应及其元件是不可缺少的,利用它观测磁场直观、干扰小、灵敏度高、效果明显。

[实验目的]1、了解霍尔效应原理及测量霍尔元件有关参数.2、测绘霍尔元件的s H I V -,M H I V -曲线了解霍尔电势差H V 与霍尔元件控制(工作)电流s I 、励磁电流M I 之间的关系。

3、学习利用霍尔效应测量磁感应强度B 及磁场分布。

4、判断霍尔元件载流子的类型,并计算其浓度和迁移率。

5、学习用“对称交换测量法”消除负效应产生的系统误差。

[实验原理]霍尔效应从本质上讲是运动的带电粒子在磁场中受洛仑兹力的作用而引起的偏转。

当带电粒子(电子或空穴)被约束在固体材料中,这种偏转就导致在垂直电流和磁场的方向上产生正负电荷在不同侧的聚积,从而形成附加的横向电场。

如右图(1)所示,磁场B 位于Z 的正向,与之垂直的半导体薄片上沿X 正向通以电流s I (称为控制电流或工作电流),假设载流子为电子(N 型半导体材料),它沿着与电流s I 相反的X 负向运动。
