They are also designed and assessed according to IEC 61508 for use in safety instrumented systems up to SIL 2.The MTLx541A provides an input for a separately-powered 4/20mA transmitter located in a hazardousarea, and repeats the transmitter current into a load in the safe area. The MTLx544A supports two identical channels for use with two separate transmitters. The MTLx541AS and MTLx544AS versions act as a current sink for the safe area connection rather than driving the current into the load.All the modules allow bi–directional transmission of HART communication signals superimposed on the4/20mA loop current, so that the transmitter can be interrogated either from the operator station or by a hand-held communicator (HHC).There are no configuration switches or operator controls to be set on the modules. These modules are members of the MTL4500 and MTL5500 range of products.1.2 Variant DescriptionFunctionally the MTL4500 and MTL5500 range of modules are the same but differ in the following way:- the MTL4500 modules are designed for backplane mounted applications- the MTL5500 modules are designed for DIN-rail mounting.In both models the hazardous area field-wiring connections (terminals 1,2, and optionally 4,5) are made through the removable blue connectors, but the safe area and power connections for the MTL454xA/MTL454xAS modules are made through the connector on the base, while the MTL554xA/MTL554xAS modules use the removable grey connectors on the top and side of the module.Note that the safe-area connection terminal numbers differ between the backplane and the DIN-rail mounting models.The analogue input models covered by this manual are:Note: To avoid repetition, further use of MTLx54xA and MTLx54xAS in this document can be understood to include both DIN-rail and backplane models. Individual model numbers will be used only where there is a need to distinguish between them.All the module types described in this manual have the same connectivity for the field signals, supporting 4-wire process transmitters or currents sourced in the hazardous area. The connection of the repeated current signals into the input measurement channels for the safety logic system follows the arrangement shown in the following diagram. When the input channels of the Safety Instrumented System (SIS) are providing power for the loop, the ‘S’ variants of the isolator modules are used to ‘sink’ the measuring current.In the other cases the isolator modules ‘source’ the measuring current that flows into a load resistor inside theinput card of the Safety Instrumented System.4SM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 22+1-Pwr (Safe area current source)B A 2+1-Pwr A BMTL5541A, MTL5541AS 1112current source (Safe area current sink) Figure 1.1 – Input and output connections 1.3 Product build revisions covered by this manual The information provided in this manual is valid for the product build revisions listed in the following table: The product build revision is identified by the field ‘CC’ in the module Product Identification Number that appears at the bottom left-hand corner of the side label: The CC field immediately precedes the 7-digit Serial Number field, DDDDDDD. Example:5SM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 22 System configurationAn MTLx54x module may be used in single-channel (1oo1) safety functions up to SIL 2. The worked example in this manual is for a SIL 2 application.The figure below shows the system configuration and specifies detailed interfaces to the safety-related and non safety-related system components. It does not aim to show all details of the internal module structure, but is intended to support understanding for the application.Figure 2 – System ConfigurationThe MTLx54xA/MTLx54xAS modules are designed to receive an active 4-20mA signal from separatelypowered process transmitters in the hazardous area and to repeat the current flowing in the field loop to the safe-area load. The shaded area indicates the safety-related system connection, while the power supply con-nections are not safety-related. The term ‘Logic Solver’ has been used to denote the safety system performing the monitoring function of the process loop variable.Note: When using the MTLx544A/MTLx544AS dual-channel modules, it is not appropriate for both channels to be used in the same loop, or the same safety function, as this creates concerns regarding common-cause failures. Consideration must also be given to the effect of common-cause failures when both loops of a dual-channel module are used for different safety functions.2.1 Associated System ComponentsThere are many parallels between the loop components that must be assessed for intrinsic safety as well asfunctional safety. In both situations the contribution of each part is considered in relation to the whole.The MTLx54xA/MTLx54xAS modules are components in the signal path between safety-related process trans-mitters and safety-related control systems. The transmitter or other field device must be suitable for the processand have been assessed and independently verified for use in functional safety applications.The field instrument and Analogue input card of the Logic Solver shall have a normal operating range of 4-20mAbut be capable of working over an extended range of 3 to 22mA for under- and over-range. The Logic Solver shallhave the ability to detect and annunciate input currents higher than the threshold of 21mA and lower than thethreshold of 3.6mA to determine out-of-range conditions.Note that the transmission of HART data is not considered as part of the safety function and is excluded fromthis analysis. However, for HART data communication to take place, the input impedance of the receiving equip-ment must be at least 240R.3 Selection of product and implicationsThe safe area output signal from the MTLx541A/AS and MTLx544A/AS modules is within the operating range of4-20mA under normal conditions. If the field wiring to the transmitter or connection between the isolator and logicsolver is open-circuit then the loop current will fall to less than 3.6mA and close to zero. If the field wiring connectionbetween the transmitter and isolator is short-circuited, the loop current will also fall to below 3.6mA.For module types MTLx541A and MTLx544A that source the 4-20mA signal in the safe area circuit, then the currentseen by the logic solver will fall to less than 3.6mA and close to zero if the connection between the isolator and logicsolver is shorted.For module types MTLx541AS and MTLx544AS that sink the 4-20mA signal in the safe area circuit, then the currentseen by the logic solver will rise to a value greater than 21mA if the connection between the isolator and logic solveris shorted.In both cases, the fault condition must be detected by the logic solver in Functional Safety applications. This shouldalso include the detection of power supply failures which cause the output of the isolator to fall to zero mA.4 Assessment of Functional Safety4.1 Hardware Safety IntegrityThe hardware assessment shows that MTLx541A/MTLx541AS and MTLx544A/MTLx544AS modules:• have a hardware fault tolerance (HFT) of 0• are classified as Type A devices (“non-complex” component with well-defined failure modes)• have no internal diagnostic elementsThe failure rates of these modules at an ambient temperature of 45°C are as follows:*(FITs means failures per 109 hours or failures per thousand million hours)• Reliability data for this analysis is taken from IEC TR 62380:2004 Reliability Data Handbook.• Failure mode distributions are taken principally from IEC 62061:2005 Safety of Machinery.• Stated failure rates for dual-channel modules apply to a single channel.It is assumed that the module is powered from a nominal 24V dc supply and operating at a maximum ambienttemperature of 45°C.6SM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 24.2 Systematic Safety IntegrityThe MTLx54x modules have a systematic safety integrity measure of SC 2. This has been established using,as described in IEC 61508-2: 2010, section 7.4.2.2 c.compliance Route 1S4.3 SIL CapabilityConsidering both the hardware safety integrity and the systematic capability, this allows the modules to beused in safety functions up to SIL 2 in a simplex architecture (HFT=0), provided SFF ≥60% is the case for the,application. The hardware safety integrity assessment has been conducted according to compliance Route 1Has described in IEC 61508-2:2010, section 7.4.4. (See example below).Note:• Independent of hardware architecture and systematic capability considerations, the hardware probability offailure for the entire safety function needs to be calculated for the application to ensure the required PFH (for ahigh or continuous demand safety function) or PFD AVG (for a low demand safety function) for the SIL is met.4.4 Example of use in a safety functionIn this example, the application context is assumed to be:• the safety function is to repeat current within ±2%• the logic solver will diagnose currents above 21mA and below 3.6mA as faults and take appropriateactionThe failure modes shown above can then be defined as:The failure rates of the MTL4541A and MTL5541A for these categories are then (FITs):In this example, the safe failure fraction (SFF) is 84.4%.*ne is not used in the calculation of SFF. Defining the “output current correct within ±2%” failure mode asrepresents a conservative approach to the calculation of SFF. Interpreting this failure mode as su(safe,neundetected) may also be considered and yields an SFF value of 87.7%.Accordingly, the SFF of all module types described in this manual, when used in the same application,are as follows:SM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 274.5 E M CThe MTL4500 and MTL5500 modules are designed for operation in normal industrial electromagnetic environ-ment but, to support good practice, modules should be mounted without being subjected to undue conductedor radiated interference, see Appendix A for applicable standards and levels.4.6 EnvironmentalThe MTL4500 and MTL5500 modules operate over the temperature range from -20°C to +60°C, and at up to95% non-condensing relative humidity.The modules are intended to be mounted in a normal industrial environment without excessive vibration, asspecified for the MTL4500 & MTL5500 product ranges. See Appendix A for applicable standards and levels.Continued reliable operation will be assured if the exposure to temperature and vibration are within the valuesgiven in the specification.5 InstallationThere are two particular aspects of safety that must be considered when installing the MTL4500 or MTL5500modules and these are:• Functional safety• Intrinsic safetyReference must be made to the relevant sections within the instruction manual for MTL4500 range (INM4500)or MTL5500 range (INM5500) which contain basic guides for the installation of the interface equipment tomeet the requirements of intrinsic safety. In many countries there are specific codes of practice, together withindustry guidelines, which must also be adhered to.Provided that these installation requirements are followed then there are no additional factors to meet theneeds of applying the products for functional safety use.To guard against the effects of dust and water the modules should be mounted in an enclosure providing atleast IP54 protection degree, or the location of mounting should provide equivalent protection such as inside anequipment cabinet.In applications using MTL4500 range, where the environment has a high humidity, the mounting backplanesshould be specified to include conformal coating.8SM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 26 M aintenanceTo follow the guidelines pertaining to operation and maintenance of intrinsically safe equipment in a hazardousarea, yearly periodic audits of the installation are required by the various codes of practice. In addition, proof-testing of the loop operation to conform with functional safety requirements should be carried out at theintervals determined by safety case assessment.Proof testing must be carried out according to the application requirements, but it is recommended that this becarried out at least once every three years.Refer to Appendix B for the proof testing procedure of the MTLx541A/AS and MTLx544A/AS modules.Note that there may also be specific requirements laid down in the E/E/PE operational maintenance procedurefor the complete installation.If an MTLx541A/AS and MTLx544A/AS module is found to be faulty during commissioning or during the normallifetime of the product, then such failures should be reported to the local MTL office. When appropriate, a Cus-tomer Incident Report (CIR) will be notified by Eaton to enable the return of the unit to the factory for analysis.If the unit is within the warranty period then a replacement unit will be sent.Consideration should be given to the service lifetime for a device of this type, which is in the region of tenyears. Operating an MTLx541A/AS and MTLx544A/AS module for longer than this period could invalidate thefunctional safety analysis, meaning that the overall safety function no longer meets its target SIL. If high failurerates of the MTL modules are detected, indicating that they have entered the ‘end of life phase’ of their servicelife, then they should be replaced promptly.7 Appendices7.1 Appendix A: Summary of applicable standardsThis annex lists all standards referred to in the previous sections of this document:SM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 2910SM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 27.2 Appendix B: Proof T est Procedure, MTLx541A/AS, MTLx544A/AS ModulesConfirmation, through testing, that a safety function will operate as designed, is a necessary periodic activity to ensure that the probability of failure upon demand (PFDavg) is maintained.In some applications, the user may prefer to conduct a proof test on the overall safety instrumented function without dismantling or disconnecting the individual instrumentation components, in order to avoid disturbing the integrity of the installation.However, where it is deemed desirable to perform proof testing on the MTL modules individually, thefollowing procedure may be used. Proof tests of the other components of the loop must then be conducted in accordance with their manufacturers’ instructions, to maintain the integrity of the overall safety function. Alternative proof tests may be devised and applied, provided they give a similar level of test coverage that is appropriate to the safety function.The tests described here - see Figure 7.1 - compare the output current of the MTL isolator with the input current (A1) over the required range of operation, and measure the “error current” i.e. the difference between the two - as indicated on A2. The tests should be employed per channel, as appropriate.Figure 7.1 - Basic test arrangementAmmeter A2 must be capable of measuring currents of either polarity. If it is not an auto-ranging instrument, set it to a high range before switch on, and then adjust sensitivity to obtain the required reading.Proof T est ProcedureTest sequence:1.

If the module is in a faulty or de-energised loop, restore normal fault-free and energisedoperation before testing.2 Input/Output characteristic functional safety testObserve normal anti-static precautions when handling equipment during device testing. Remove the unit fromthe target system and connect it as shown in Figure 7.2. This figure shows the arrangement for the MTLx541A/AS single-channel modules; for equivalent connections for the MTLx544A/AS dual-channel modules, refer tothe relevant product data sheets. Note that it is acceptable to leave the unit in the target system but only afterensuring that the all the hazardous area input and safe area output terminals have been disconnected from thesystem and are available for test. Alternatively, for the backplane-mounted MTL4500 range modules, a separatebackplane can be used to provide access to the power and output connections.Note that the combination of the 24V power supply and variable resistor RV1 in the hazardous area connectioncan be provided by a suitable industrial current simulator, which is likely to be more readily available. Also,the 250R resistor does not need to be a precision type; any value in the range 200-300R is acceptable wouldsuffice, such as a standard value of 240R.Where a second power supply is introduced for testing the MTLx541AS or MTLx544AS module variants, notethat both power supplies must be floating and not share a common 0V connection.During testing, a 24V nominal system power supply in the range 20.0 to 35.0V should be connected betweenterminals 13 and 14 (+ve to terminal 14).Figure 7.2 - Connections for testing the MTL5541A/AS and MTL4541A/AS modulesSM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 21112SM4541A/AS, 5541A/AS, 4544A/AS, 5544A/AS rev 2Channel 1Channel 2MeasurementsMake the following measurements. It is recommended to record the results in a table such as that shown on the next page. 1. Adjust resistor RV1 to vary the loop current (measured by Ammeter A1) through the range 4 to 20mA. (Tests 1 - 5 in table)2. The measured current imbalance (measured by Ammeter A2) over this range should not exceed ±50μA.3. Adjust RV1 to vary the current (A1) to 3.5mA and then 21.5mA (tests 6 & 7 in table).4. The measured current imbalance (A2) at these currents should not exceed ±200μA.5. Record the supply voltage Vs.If appropriate, repeat these measurements for Channel 2.3 System - Normal operation testDisconnect the test setup from the unit and reconnect the original system configuration.

蓝牙模块的工作方式全面分析一、广播模式蓝牙模块被设置成beacon广播模式，被作为蓝牙基站或信标使用，可以用来推送信息使用。

蓝牙模块工作在beacon广播模式二、主从模式蓝牙模块通信是指两个蓝牙模块或蓝牙设备之间进行通信，进行数据通信的双方一个是主机，一个是从机。

主机是指能够搜索别人并主动建立连接的一方，从机则不能主动建立连接，只能等别人连接自己。

蓝牙4.0模块由于协议限制，一个蓝牙模块的当前状态只能处于其中的一种，要么主机，要么从机。

支持主从模式的蓝牙模块是指能够在主机模式和从机模式之间切换，可以选择工作在主机模式下，也可以选择工作在从机模式下。

三、主从一体模式支持主从一体的的蓝牙模块允许蓝牙模块同时作为主设备和从设备。

举一个家庭自动化的例子。

比如如下场景：一个家庭有小宝宝，父母想要密切监视他们家的空气质量。

他们购买了多个传感器散布在房间周围，中央显示屏显示空气质量，这是本地的解决方案。

如果窗户意外地打开，父母在楼上可能听不到中央单位的警报报警。

主从一体多角色的蓝牙模块可以避免这种情况，传感器数据不再限于在本地显示。

现在可以在系统中连接智能手机，并且可以在云端收集数据。

家长可以在中央单元和智能手机上查看空气过敏原警告，增加他们孩子的保护。

蓝牙模块工作在主从一体模式在这个场景中，蓝牙模块MS50SFA使用了主从一体功能。

在中央显示单元中，MS50SFA工作在主从一体模式，用作主机收集并显示来自空气传感器节点（外围设备）的数据，同时作为从机将传感器数据或警报中继到作为BLE主机的智能手机。

四、扫描模式蓝牙模块工作在扫描模式是指能够扫描周围工作在从机模式或者beacon模式的蓝牙模块。

蓝牙模块工作在扫描模式内嵌蓝牙模块MS50SFA1的蓝牙MAC地址扫描设备充当主机角色，扫描周边设备，根据广播名称过滤，筛选出周边信号最强的设备，获取MAC地址；再进一步上传，通过标签打印机打印出符合要求的二维码。

五、连接模式蓝牙模块工作在连接模式是指两个蓝牙模块一主一从连接进行数据传输。

MIC45116 Evaluation Board20V/6A/DC-to-DC Power ModuleGeneral DescriptionMicrel’s MIC45116 is a synchronous step-down regulatormodule, featuring a unique adaptive ON-time controlarchitecture. The singular module package includes a DC-to-DC controller, power MOSFETs, bootstrap diode,bootstrap capacitor, and an inductor; simplifying the designand layout process for the end user.This highly integrated solution expedites system designand improves product time-to-market. The internalMOSFETs and inductor have been optimized to achievehigh efficiency at a low output voltage. The fully optimizeddesign can deliver up to a 6A current under a wide inputvoltage range of 4.75V to 20V, without an additionalcooling requirement.The MIC45116-1 uses Micrel’s HyperLight Load®(HLL).MIC45116-2 uses Micrel’s Hyper Speed Control™architecture which enables ultra-fast load transientresponse and allows for a reduction of output capacitance.The MIC45116 offers 1% output accuracy that can beadjusted from 0.8V up to 85% of the input voltage with twoexternal resistors. Note the output capacitor Cb is onlyrated to 6.3V.The basic parameters of this evaluation board include a4.75V to 20V input, a 0.8V to 5V at 6A output.Datasheets and support documentation are available onMicrel’s web site at: .RequirementsThe MIC45116-1 and MIC45116-2 evaluation board’sminimum requirement is one power supply with at least 6Acurrent capability. No external linear regulator is requiredto power the internal biasing of the IC because theMIC45116 has an internal PVDD LDO. In the applicationswith VIN < +5.5V, PVDD should be tied to VIN to bypassthe internal linear regulator. The output load can either bea passive or an active load.PrecautionsThe MIC45116 evaluation board does not have reversepolarity protection. Applying a negative voltage to the VINand GND terminals may damage the device. Themaximum VIN of the board is rated at 20V. Exceeding 30Von the VIN could damage the device. The voltage rating ofthe output capacitor is 6.3V. The output capacitor shouldbe replaced with higher voltage rated one to set the outputvoltage above 5V.Getting Started1. VIN SupplyConnect a supply to the VIN (TP6) and GND (TP7)terminals, paying careful attention to the polarity andthe supply range (4.75V < VIN < 20V). Monitor IIN witha current meter and monitor input voltage at VIN andGND terminals with a voltmeter. Do not apply poweruntil Step 4.2. Connect Load and Monitor OutputConnect a load to the VOUT (TP8) and GND (TP9)terminals. The load can be either a passive (resistive)or an active (as in an electronic load) type. A currentmeter may be placed between the VOUT terminal andload to monitor the output current. Ensure the outputvoltage is monitored at the VOUT terminal.3. Enable InputThe EN pin has an on board 100kΩ pull-up resistor(R4) to VIN, which allows the output to be turned onwhen PVDD exceeds its UVLO threshold. An ENconnector (TP3) is provided on the evaluation boardfor users to easily access the enable feature. Applyingan external logic signal on the EN pin to pull it low orusing a jumper to short the EN pin to GND will shut offthe output of the MIC45116 evaluation board.4. Turn PowerTurn on the VIN supply and verify that the outputvoltage is regulated to 1.8V.5. Loop MeasurementControl loop frequency response can be measured byinjecting AC sweep signal and measuring voltageacross test points A and B. R3 should change to asmall resistor value in the range of 10Ω to 20Ω for theloop measurement.Ordering InformationPart Number DescriptionMIC45116-1YMP EV MIC45116-1 Evaluation BoardMIC45116-2YMP EV MIC45116-2 Evaluation BoardHyper LightLoad is a registered trademark of Micrel, Inc.FeaturesFeedback ResistorsThe output voltage on the MIC45116 evaluation board, which is preset to 1.8V, is determined by the feedback divider, as illustrated in Equation 1:+×=BOTTOM REF OUTR R511V VEq. 1where V REF = 0.8V, and R BOTTOM is the lower feedbackresistor.Leaving the R BOTTOM open by removing all jumpers on the feedback headers gives a 0.8V output voltage. All other voltages not listed above can be set by modifying R BOTTOM value according to Equation 2:REFOUT REF BOTTOM V V V R51R −×= Eq. 2Note that the output voltage should not be set to exceed 5V unless the output capacitor (C6) is replaced with a higher voltage rating.Table 1.

It is one of the most critical waveforms for the converter.Current LimitThe MIC45116 uses the R DS(ON) of the low-side MOSFET and external resistor connected from the ILIM pin to the SW node to decide the current limit.VINFigure 1. MIC45116 Current-Limiting CircuitIn each switching cycle of the MIC45116, the inductor current is sensed by monitoring the low-side MOSFET in the OFF period. The sensed voltage (V (ILIM)) is compared with the power ground (PGND) after a blanking time of 150ns. In this way the drop voltage over the R26 resistor (V CL ) is compared with the drop over the bottom FET generating the short current limit. The small capacitor (C16) connected from ILIM pin to PGND filters the switching node ringing during the off-time allowing a better short-limit measurement. The time constant created by R26 and C16 should be much less than the minimum off time.The V CL drop allows programming of short limit through the value of the resistor (R26) if the absolute value of the voltage drop on the bottom FET is greater than V CL . In that case the V (ILIM) is lower than PGND and a short circuit event is triggered. A hiccup cycle to treat the short event is generated. The hiccup sequence including the soft-start reduces the stress on the switching FETs and protects the load and supply for severe short conditions.The short-circuit current limit can be programmed by using Equation 3:()CLCLDS(ON)PP L CLIM I V R 0.5)ΔI (I R26+××−=Eq. 3where:I CLIM = Desired current limitR DS(ON) = On-resistance of low-side power MOSFET, 16mΩ CL = Current-limit threshold (typical absolute value is = Current-limit source current (typical value is 80µA, L(PP) = Inductor current peak-to-peak, since the inductor Equation 4 to calculate the inductor Lf V )V (V V I sw IN(MAX)OUT IN(MAX)OUT L(PP)××−×=∆ Eq. 4The MIC45116 has 1.0µH inductor integrated into the module. In case of hard short, the short limit is folded down to allow an indefinite hard short on the output without any destructive effect. It is mandatory to make sure that the inductor current used to charge the output capacitance during soft start is under the folded short limit; otherwise the supply will go in hiccup mode and may not be finishing the soft start successfully.The MOSFET R DS(ON) varies 30% to 40% with temperature. Therefore, it is recommended to add a 50% margin to I CLIM in the above equation to avoid false current limiting due to increased MOSFET junction temperature rise.
