常见的霍尔元件
常见的霍尔元件常见的霍尔元件有哪些种类，型号？单极性霍尔单极开关介绍:单极霍尔效应开关具有磁性工作阈值(Bop)。
如果霍尔单元承受的磁通密度大于工作阈值，那么输出晶体管将开启；当磁通密度降至低于工作阈值(Brp) 时，晶体管会关闭。
滞后(Bhys) 是两个阈值(Bop-Brp) 之间的差额。
即使存在外部机械振动及电气噪音，此内置滞后页可实现输出的净切换。
单极霍尔效应的数字输出可适应各种逻辑系统。
这些器件非常适合与简单的磁棒或磁杆一同使用。
Allegro 提供各种单极霍尔效应开关，各开关均具有与磁铁南极相关的不同工作阈值及滞后。

hall开关工作原理
hall开关工作原理今天咱们来唠唠这个超有趣的Hall开关呀。
你知道吗？Hall开关就像是一个小小的魔法器件呢。
想象一下，在一个微观的世界里，有这么一个东西在悄悄地感知着周围磁场的变化，然后像个机灵的小卫士一样做出反应。
那它到底是怎么做到的呢？这就得从它的内部结构说起啦。
Hall开关里面有个很关键的部分，叫Hall元件。
这个Hall元件呀，就像是一个超级敏感的磁场探测器。
当有磁场靠近它的时候，就会发生一些奇妙的事情哦。
在没有磁场的时候呢，Hall元件内部的电子是比较“自由散漫”地在跑来跑去的，就像一群调皮的小娃娃在一个空旷的场地里随意玩耍。
可是一旦有磁场来了，就像是一个严厉的老师走进了操场，这些电子就开始变得“规规矩矩”了。
磁场会对电子产生一种力，让它们在元件内部重新分布。
这种重新分布就会导致元件两边出现电压差。
哇塞，是不是很神奇呀？就这么悄咪咪地，因为磁场的到来，电压就发生了变化。
那这个电压变化有啥用呢？这可就和Hall开关的功能紧密相连啦。
当这个电压差达到一定的值，就像是触发了一个机关一样，Hall开关就会改变它的输出状态。
比如说，原来它输出的是低电平，就像在安静地休息，一旦磁场触发了这个电压变化达到了临界值，它就会一下子变成高电平，就像突然兴奋起来一样。
我们可以把Hall开关想象成一个有特殊本领的小宠物。
平常呢，它就在那安安静静地待着，对周围的普通东西都不怎么在意。
但是只要一有磁场这个特殊的“信号”，就像是主人给了它一个特殊的指令，它就立马做出反应。
而且呀，这个磁场的强度和方向不同，还会让Hall开关有不同的表现呢。
就好像小宠物对不同的指令有不同的回应一样。
在实际的应用里，Hall开关可是无处不在的大明星哦。
在我们的手机里，它可能就在负责检测手机翻盖或者滑盖的开合状态呢。
当我们合上手机盖的时候，有个小磁铁靠近了Hall开关，它就知道手机盖合上了，然后就可以通知手机做出相应的操作，比如关闭屏幕啦。
hall开关原理
hall开关原理
Hall开关是一种基于霍尔效应的电子开关。
霍尔效应是指当电流流过一个导电材料时，如果垂直于电流方向施加一个磁场，会在导电材料中产生一种电势差。
Hall开关利用这种电势差来控制开关状态。
Hall开关由霍尔传感器、放大器和开关电路组成。
当有磁场作用于霍尔传感器时，传感器产生的电势差会被放大器放大，然后经过开关电路控制开关状态。
当无磁场作用于霍尔传感器时，电势差较小，开关处于关闭状态；当有磁场作用于霍尔传感器时，电势差增大，开关被打开。
Hall开关具有以下优点：
1. 高可靠性：Hall开关没有机械接触，没有磨损和接触电阻，因此寿命较长，稳定性较高。
2. 快速响应：Hall开关的响应时间短，可以快速切换开关状态。
3. 低功耗：Hall开关工作时，只有在状态切换时才需要消耗能量，因此功耗较低。
4. 广泛应用：Hall开关可以应用于各种场景，如磁传感器、车辆传感器、工业自动化等。
总之，Hall开关利用霍尔效应实现开关控制，具有高可靠性、快速响应、低功耗等优点，广泛应用于各个领域。
OCH165 微功耗单极性HALL(霍尔)效应开关
TSOT23-3L (Top View)Pin NamePin No.Pin FunctionTSOT23-3LVDD 1 Power Supply Input GND 3 Ground OUTPUT 2 Output PinGeneral DescriptionThe OCH165 Unipolar Hall effect sensor IC is fabricated from mixed signal CMOS technology. It is comprised of one Hall plate and a CMOS output driver, mainly designed for battery-operation, hand-held equipment (such as Cellular and Cordless Phone, PAD). The total power consumption in normal operation is typically 21μW with a 3V power source. South poles of sufficient strength will turn the output on. The output will be turned off under no magnetic field. While the magnetic flux density (B) is larger than operating point (BOP), the output will be turned on (low), the output is held until B is lower than release point (BRP), and then turned off. The OCH165 is available in TSOT23-3L Package. Operating temperature range of the OCH165 is from -40°C to 85°C. To minimize the BOM cost, capacitors of the MLCC type are supported, and only one external component is needed to complete the application circuit.FeatureszMicro power consumption ideal for battery-powered applicationsz Input Voltage Range: 2.5V to 3.65V z Very High Sensitivity Hall Sensor z Chopper stabilized amplifier stage z Good RF noise immunity z TSOT23-3L packagez Not need the push-high resistanceApplicationsz Cover switch in clam-shell cellular phones z Cover switch in Notebook PC/PADz Contact-less switch in consumer products z Solid State Switchz Handheld Wireless Handset Awake Switch z Lid close sensor for battery-powered devisez Magnet proximity sensor for reed switchreplacement in low duty cycle applicationsPin ConfigurationTypical Application CircuitNote: C is for power stabilization and to strengthen the noise immunity, the recommended capacitance is10nF~100nF.Block DiagramAbsolute Maximum Ratings1 (T A=25°C unless otherwise noted)Parameter Symbol Rating UnitVDD to GND V DD-0.3 to 4.5VMagnetic Flux Density B UnlimitedStorage Temperature Range T S-55 to +150 ℃Operating Junction Temperature Range T J-40 to 150 ℃mW Package Power Dissipation TSOT23-3L P D 400Recommended Operating Conditions (T=25°C unless otherwise noted)AParameter Symbol Conditions Rating UnitSupply Voltage V DD Operating 2.5 ~ 3.65 V℃+85~ Operating Temperature Range T A Operating -40Electrical Characteristics(Unless otherwise noted ，typical values are at T A =25℃, V DD =3V) Symbol ParameterConditionsMin.

A short"awake" time allows for stabilization prior to the sensor sampling and data latching onthe falling edge of the timing pulse. Theoutput during the "sleep" time is latched inthe last sampled state. The supply currentis not affected by the output state.Chopper-Stabilized TechniqueThe Hall element can be considered as a resistor array similar to a Wheatstone bridge. A large portion of the offset is a result of the mismatching of these resistors. These devices use a proprietary dynamic offset cancellation technique, with an internal high-frequency clock to reduce the residual offset voltage of the Hall element that is normally caused by device over-molding, temperature dependencies, and thermal stress. The chopper-stabilizing technique cancels the mismatching of the resistor circuit by changing the direction of the current flowing through the Hall plate using CMOS switches and Hall voltage measurement taps, while maintains the Hall voltage signal that is induced by the external magnetic flux. The signal is then captured by a sample-and-hold circuit and further processed using low-offset bipolar circuitry. This technique produces devices that have an extremely stable quiescent Hall output voltage, are immune to thermal stress, and have precise recoverability after temperaturecycling. A relatively high sampling frequency is used for faster signal processing capability can be processed.Magnetic Field Detection MechanismThe Hall IC cannot detect magnetic fields that run horizontal to the package top layer. Be certain to configure the Hall IC so that the magnetic field is perpendicular to the top layer.OperationThe output of this device switches low (turns on) when a magnetic field perpendicular to the Hall sensor exceeds the operate point BOPS. After turn-on, the output is capable of sinking up to 1mA and the output voltage is V OUT (ON). When the magnetic field is reduced below the release point BRPS, the device output switches high (turns off). The difference between the magnetic operates and release points are the hysteresis (Bhys) of the device. This built-in hysteresis allows clean switching of the output even in the presence of external mechanical vibration and electrical noise.Applications:OCH165's pole-independent sensing technique allows for operation with either a north or south poles magnet orientation, enhancing the manufacturability of the device. The state-of-the-art technology provides the same outputpolarity for either pole face.C1 serves two purposes: minimizing ripples on the input voltage and enhancing immunity from RF transmission noises within close proximity. Recommended values are between 10nF and 100nF. The larger the capacitance, the better the noise immunity is for the OCH165.It is strongly recommended that an external bypass capacitor 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. The simplest form of magnet that will operate these devices is a bar magnet with either pole near the branded surface of the device.Ordering InformationMarking InformationTSOT23-3LPart Number Package Type Package Qty B RPS (Gauss) B OPS (Gauss) Temperature Eco Plan Lead OCH165TWAD TSOT23-3L7-in reel 3000pcs/reel50 ~ 10080 ~ 150-40～85℃GreenCuPackage Information TSOT23-3LSymbol Dimensions In Millimeters Dimensions In Inches Min.

hall开关原理
Hall开关原理及应用1. Hall效应的基本原理Hall效应是指当电流通过一块导体时，在垂直于电流方向和磁场方向的平面内，会产生一种电势差。
这种现象是由于电子在磁场中受到洛伦兹力的作用而引起的。
具体来说，当电流通过一块导体时，导体内的自由电子将受到磁场力的作用，偏转方向与电子运动方向、磁场方向以及载流子类型有关。
根据洛伦兹力的方向可知，在正常情况下，正负载流子分别受到力的作用后沿着不同方向偏转。
这种偏转将导致在导体两侧产生一个电势差，称为Hall电势差（VH）。
2. Hall开关的基本原理Hall开关利用了Hall效应，并结合了磁性材料和控制器件等元件，实现了对磁场变化敏感并能够控制其他设备工作状态的功能。
一个典型的Hall开关通常包括以下几个部分：2.1 磁性材料在Hall开关中，通常使用铌铁（Permalloy）等具有高磁导率和低矫顽力的材料作为磁性材料。
这种材料可以增强磁场对Hall元件的影响，提高开关的灵敏度。
2.2 Hall元件Hall元件是Hall开关的核心部分，它通常由半导体材料制成，如镓砷化物（GaAs）或硅（Si）。
Hall元件具有两个侧面接触端和一个中间探测端。
当电流通过Hall元件时，在垂直于电流方向和磁场方向的平面内会产生一个电势差。
2.3 控制器件控制器件用于检测Hall元件产生的电势差，并根据电势差的大小来控制其他设备的工作状态。
常见的控制器件包括运算放大器、比较器、数字转换器等。
2.4 磁场源磁场源用于提供一个外部磁场，使得Hall开关能够感知到磁场变化。
常见的磁场源包括永久磁铁、电磁铁等。
3. Hall开关的工作原理当外部磁场施加在Hall开关上时，由于Hall效应，会在Hall元件中产生一个电势差。
控制器件会检测到这个电势差，并根据设定的阈值来判断磁场的强度是否超过预设值。
当磁场强度超过预设值时，控制器件将触发一个开关信号，使得其他设备工作或停止工作。
例如，可以通过Hall开关来控制灯光的开关，当磁场强度达到一定程度时，灯光自动打开或关闭。
