Thealarm will be unblocked after the process reaches a non-alarm condition for the first time.In a multiple stage application, SP1and SP2are configured to operate at differenttemperatures, creating a progressive sequence for turning on the outputs(compressors) in response to a system demand. The output delays for turning on thecompressors (dL1and dL2) cause the compressors to be turned on one by one,minimizing energy demand.Another usage for multiple output controllers is in systems that require automaticselection between cool and heat action. In these applications, one output is configuredas reverse action (heating) and the other as direct action (refrigeration). The outputstatus led P1 and P2 in the controller panel, signals when the control output in on.CONFIGURATION PROTECTIONA protection system to avoid unwanted changes to the controller parametersis implemented. The level of protection can be selected from partial to full. The followingparameters are part of the protection system:Pas When this parameter is presented, the correct password should be entered toallow changes of parameters in the following levels.Prt Defines the level of parameters that will be password protected:1 - Only calibration level is protected (factory configuration);2 - Calibration and Configuration levels are protected;3 - All levels are protected - calibration, Configuration and setpoints.PA(Parameter for definition of a new password. Since it is located in the calibrationlevel, can only be changed by a user that knows the current password. Validpasswords are in the range 1 to 999.Configuration protection usagePAS parameter is displayed before entering a protected level. If the correct password isentered, parameters in all following levels can be changed. If wrong or no password isentered, parameters in the following levels will be read only.Important notes:1- After five consecutive attempts to enter a wrong password, new tentative will beblocked for the next 10 minutes. If the current valid password is unknown, the masterpassword can be used only to define a new password for the controller.2 - The password for a brand new device is 111.MASTER PASSWORDThe master password allows user to define a new password for the controller, even ifthe current password is unknown. The master password is based in the serial numberof the controller, and calculated as following:[ 1 ] + [ higher digit of SN2 ] + [ higher digit of SN1 ] + [ higher digit of SN0 ]For example the master password for the device with serial number 987123465 is: 1 9 3 6as follows: 1 +sn2= 987; sn1= 123; sn0= 465 = 1 + 9 + 3 + 6How to use the master password:1- Enter the master password value at PaS prompt.2- Go to PA( parameter and enter the new password, which must not be zero (0).3- Now you can use this new password to access all controller parameters with modifyrights.ERROR MESSAGESSensor measurement errors force the controller outputs to be turned off. The cause forthese errors may have origin in a bad connection, sensor defect (cable or element) orsystem temperature outside the sensor working range.

The parts are fully specified with a single +12 V power supply and will remain functional with single supplies as low as +5 V.GENERAL DESCRIPTIONThe ADG411, ADG412 and ADG413 are monolithic CMOS devices comprising four independently selectable switches. They are designed on an enhanced LC 2MOS process which provides low power dissipation yet gives high switching speed and low on resistance.The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion whenswitching audio signals. Fast switching speed coupled with high signal bandwidth also make the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipa-tion making the parts ideally suited for portable and battery powered instruments.The ADG411, ADG412 and ADG413 contain four indepen-dent SPST switches. The ADG411 and ADG412 differ only in that the digital control logic is inverted. The ADG411 switches are turned on with a logic low on the appropriate control input,while a logic high is required for the ADG412. The ADG413has two switches with digital control logic similar to that of the ADG411 while the logic is inverted on the other two switches.Each switch conducts equally well in both directions when ON and each has an input signal range that extends to the supplies.In the OFF condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching ac-tion for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.查询ADG411供应商捷多邦，专业PCB打样工厂，24小时加急出货ADG411/ADG412/ADG413–SPECIFICATIONS1Dual Supply(V DD = +15 V ؎ 10%, V SS = –15 V ؎ 10%, V L = +5 V ؎ 10%, GND = 0 V, unless otherwise noted)B Version T Version–40؇C to–55؇C toParameter+25؇C+85؇C+25؇C+125؇C Units Test Conditions/Comments ANALOG SWITCHAnalog Signal Range V DD to V SS V DD to V SS VR ON2525Ω typ V D = ±8.5 V, I S = –10 mA;35453545Ω max V DD = +13.5 V, V SS = –13.5 V LEAKAGE CURRENTS V DD = +16.5 V, V SS = –16.5 V Source OFF Leakage I S (OFF)±0.1±0.1nA typ V D = ±15.5 V, V S = ϯ15.5 V;±0.25±5±0.25±20nA max Test Circuit 2Drain OFF Leakage I D (OFF)±0.1±0.1nA typ V D = ±15.5 V, V S = ϯ15.5 V;±0.25±5±0.25±20nA max Test Circuit 2Channel ON Leakage I D, I S (ON)±0.1±0.1nA typ V D = V S = ±15.5 V;±0.4±10±0.4±40nA max Test Circuit 3DIGITAL INPUTSInput High Voltage, V INH 2.4 2.4V minInput Low Voltage, V INL0.80.8V maxInput CurrentI INL or I INH0.0050.005µA typ V IN = V INL or V INH±0.5±0.5µA maxDYNAMIC CHARACTERISTICS2t ON110110ns typ R L = 300 Ω, C L = 35 pF;175175ns max V S = ±10 V;

Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.Although the ADG411/ADG412/ADG413 feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.ADG411/ADG412/ADG413Typical Performance GraphsFigure 1.On Resistance as a Function of V D (V S ) Dual Supplies Figure 2.On Resistance as a Function of V D (V S ) for Different TemperaturesFigure 3.Leakage Currents as a Function of TemperatureFigure 4.On Resistance as a Function of V D (V S ) Single SupplyFigure 5.Supply Current vs. Input Switching FrequencyFigure 6.Leakage Currents as a Function of V D (V S )ADG411/ADG412/ADG413Figure 7.Off Isolation vs. Frequency Figure 8.Crosstalk vs. Frequency APPLICATIONFigure 9 illustrates a precise, fast, sample-and-hold circuit. An AD845 is used as the input buffer while the output operational amplifier is an AD711. During the track mode, SW1 is closed and the output V OUT follows the input signal V IN. In the hold mode, SW1 is opened and the signal is held by the hold capaci-tor C H.Due to switch and capacitor leakage, the voltage on the hold capacitor will decrease with time. The ADG411/ADG412/ADG413 minimizes this droop due to its low leakage specifica-tions. The droop rate is further minimized by the use of a poly-styrene hold capacitor. The droop rate for the circuit shown is typically 30 µV/µs.A second switch, SW2, which operates in parallel with SW1, is included in this circuit to reduce pedestal error. Since both switches will be at the same potential, they will have a differen-tial effect on the op amp AD711, which will minimize charge injection effects. Pedestal error is also reduced by the compensa-tion network R C and C C. This compensation network also re-duces the hold time glitch while optimizing the acquisition time. Using the illustrated op amps and component values, the pedes-tal error has a maximum value of 5 mV over the ±10 V input range. Both the acquisition and settling times are 850 ns.Figure 9.Fast, Accurate Sample-and-HoldADG411/ADG412/ADG413Test Circuit 1.On ResistanceTest Circuit 3.On LeakageTest CircuitsTest Circuit 2.Off LeakageTest Circuit 4.Switching TimesTest Circuit 5.Break-Before-Make Time DelayTest Circuit 6.Charge InjectionADG411/ADG412/ADG413C 1748a –3–2/98Test Circuit 8.Channel-to-Channel CrosstalkTest Circuit 7.Off Isolation P R I N T E D I N U .S .A .16-Lead Cerdip(Q-16)16-Lead Plastic DIP (Narrow)(N-16)MECHANICAL INFORMATIONDimensions are shown in inches and (mm).16-Lead SOIC (R-16A)16-Lead TSSOP(RU-16)。

32寸LG屏等离子电源板EAY40484901电路原理简介与维修
长虹32寸LG屏等离子电源板EAY40484901/902电路原理简介与维修方法(一)电源输入EMC电路与 PFC电路1、EMC电源滤波电路（1）互感线圈LF101、LF102和电容C101、C104、C105构成一个抗干扰电路，主要是用来滤除交流电源中的高频干扰。
（2）TH601、TH602热敏电阻，用于冷机开机时防止电源瞬间浪涌电流损坏其他元件。
（3）R101放电电阻，因为电源输入端阻抗达MΩ以上，所以关机后电阻给C101、C104、C105放电。
（4）VA101压敏电阻，电压过高内阻迅速下降而烧断保险丝，主要起保护作用，防止故障扩大。
2、PFC(有源功率因数校正)电路FAN5501A个脚功能介绍序号（脚）功能序号（脚）功能1 PFC高压检测 5 过零、过压检测2 参数设定 6 GND3 低压输入7 驱动输出4 电流反馈8 供电14V维修提示：EMC电源滤波电路损坏器件比较少，一般烧保险，多为PFC电路开关管Q602或Q603其中一个或两个损坏造成。
判断PFC电路是否工作，测大滤波电容C617或618两脚电压，如果有300V，说明PFC 电路没工作，需要重点查一下PFC芯片FAN5501A第⑧脚供电对不对，该供电受CPU控制，如果PFC芯片供电14V正常，还没有PFC电压(380V),多为PFC芯片FAN5501A①脚外接检测电阻R614、R615、R616、R617阻值变小所致（电阻下面有胶漏电造成电阻变小），维修过程中只需把电阻拆下来，再把贴片电阻下面和印制板上的胶处理干净从新安装电阻即可；如电压是380V左右，说明PFC电路工作正常，就不用查PFC电路。
PFC开关管：Q603Q602PFC检测电阻R614、R615R616、R617滤波电容：C617 C618（二）电压检测电路1、低压检测电路：220V交流电经D125、R144、 R142、 R123、 R137、 R138、 C126半波整流、滤波后变成直流电压，再经R139、 R140 、R141分压，给U121参考端提供一个大于2.5V电压，此时TL431阴极电位下降，PC151光耦导通，CPU IC701（17）脚有5V开机工作信号，CPU收到信号后25脚由低电位变成高电位控制5Vstb输出电压。
液晶显示屏背光灯及高压驱动电路原理与故障维修
但是为了保证电容C和电感L的谐振频率就是振荡器的振荡频率，又要使电容C的容抗XC的大小基本正好是灯管的限流值，电路的精确设计是至关重要的。
在维修中，电容C是比较容易损坏的元件，如有损坏，一定要用和原来一样的电容代换，否则其性能会大幅下降，甚至不能使用。
对于多灯管屏的亮度控制，如果同时间断灯管的瞬间供电，PWM的间断频率会和液晶屏的刷新频率差拍，液晶屏会出现滚道干扰、闪烁、亮度不均匀等现象，为了防止这种现象产生，加于每个灯管的断续脉冲波相位上有所差异，即对灯管来说，短暂停止供电在多根灯管中，不是同时断电、供电，必须是交替轮流断电、供电。多灯管系统一般把灯管分为4组，供电系统的PWM脉冲有4个通道，输出4路经过PWM调制的高频脉冲波，每个通道向一组灯管供电，通道之间输出的PWM调制脉冲，依次移相900，这样4组灯管则达到轮流断电、供电，使亮度更均匀，干扰最小，三星32寸液晶屏有16根灯管，分为4组，每组4根灯管（24根灯管液晶屏的就每组6根灯管）。
所以目前冷阴极荧光灯的亮度控制均采用脉冲调光，具体方法是；用30～200Hz的低频PWM脉冲波（PWM脉冲波的宽度受控于CPU）对施加于冷阴极荧光灯管上的连续振荡高压进行调制，使连续振荡波变成断续振荡波，从而达到控制亮度的目的，其控制原理是；断续的在极短间内停止对冷阴极荧光灯供电，由于停止时间极短，不足以使灯管的电离状态消失，但是其辐射的紫外线强度下降，管壁上的荧光粉的激发量减小，亮度也下降，只要控制PWM的脉冲的占空比，就可以改变灯管在一个导通/关闭周期的时间比，从而达到控制灯管平均亮度的目的见图5中，调制器输出的脉冲串信号，目前的技术可以达到400：1或更高的调光控制。

士兰微电子 SD4931 电流模式 PWM 控制器 说明书
100V电流模式PWM控制器描述SD4931 是用于开关电源的内置100V高压MOSFET的电流模式PWM 控制器。
SD4931 内置高压启动电路。
在轻载下会进入打嗝模式，从而有效地降低系统的待机功耗。
具有降频功能，进一步优化轻载条件下的转换效率。
具有软启动功能，能够减小器件的应力，防止变压器饱和。
有VDD打嗝功能，不仅防止V DD欠压重启，也有效地降低待机功耗。
SD4931内部还集成了各种异常状态的保护功能，包括：VDD欠压保护，VDD过压保护，前沿消隐，输出短路保护，过流保护，过温保护等。
触发保护后，电路会不断自动重启，直到系统正常为止。
主要特点♦20V至100V输入电压♦12~15V输出电压♦1A输出电流♦高压启动♦轻载打嗝♦降频♦软启动♦VDD打嗝♦VDD欠压保护♦VDD过压保护♦前沿消隐♦输出短路保护♦过流保护♦过温保护应用♦平衡轮♦以太网供电♦电动自行车♦电动工具产品规格分类内部框图极限参数电气参数(除非特别说明, VDD =12V；Tamb=25︒C)管脚排列图管脚描述功能描述SD4931是用于开关电源的内置高压MOSFET的电流模式PWM控制器，内置高压启动电路，在轻载下会进入打嗝模式，具有降频、软启动、VDD打嗝，还集成了VDD欠压保护、VDD过压保护、前沿消隐、输出短路保护、过流保护、过温保护等各种异常状态的保护功能。
高压启动SD4931内置高压启动电路。
启动时，输入电压从DRAIN端通过内置高压启动恒流源，对VDD端外置电容进行充电，充电电流为1mA，使得VDD电压上升，当升至启动电压14.3V时，将高压启动恒流源关断，则DRAIN端对VDD 端停止充电，转由电感电压通过二极管对VDD端进行供电；如果VDD电压降至欠压保护点8.9V，则将高压启动恒流源重新打开，又由DRAIN端对VDD端进行充电，使得VDD电压上升，升至启动电压14.3V。
恒压控制SD4931通过FB脚检测VOUT的变化，当VOUT变小，流入FB脚的电流减小，从而增大输出脉宽，使VOUT上升，使输出保持恒定，VOUT电压近似等于ZD1两端电压。
