莱姆电流互感器的电路

----------专业最好文档，专业为你服务，急你所急，供你所需-------------莱姆（LEM ）电流互感器的电路1、LEM 电流互感器的原理解析在智能化较高的电子设备上，应用最多的是电子式电流互感器，其突出优点在于把普通电流传感器与霍尔元件、电子电路有机地结合起来，既沿袭了普通传感器测量范围宽的长处，又发挥了电子电路反应速度快的优势。

而且大拓展了其应用范围，可用于交流、直流及脉动电流进行测量。

该类电子式传感器，有些为非标产品，系变频器生产厂家自行制作的，通用性较差。

近年来也有一些厂家专门生产通用性较好的电子式电流传感器，本机例所采用的是莱姆电流传感器（由瑞士LEM 公司推出的产品）。

其外型、内部电路板和原理框图如图1所示。

a ）LEM 电流互感器外型b ）LEM 电流互感器内部结构c ）LEM 电流互感器内部原理框图图1 LEM 电流互感器外型、内部结构和原理框图LEM 有源电流互感器（以下简称LEM 电流互感器）为中间有透孔，三引线端的方形塑封器件，中间透孔供穿过变频器的输出电流引线，作为电流互感器的原边，穿绕匝数一般为1匝；三引线端，其中两引线为供电电源引入，一引脚为电流检测信号输出。

其内部结构含带空隙铁心（空隙处供放置霍尔元件）、副边线圈、电子电路板。

输出电流信号在外置负载电阻上，可以转化为表征着输出电流大小的线性电压信号。

LEM （LA108-P 型）电流互感器测绘电路，如图9-4所示。

注：为便于原理分析，图中元件序号为作者所添加。

图2 LEM （LA108-P 型）电流互感器测绘电路图LEM 电流互感器的工作原理（参见图9-3c ）电路与图9-4电路）：LEM 电流互感器的原理是磁场平衡式的，由闭环控制完成零磁通检测的任务。

即主电流回路所产生的磁场，通过一个次线线圈L1（1000匝，直流电阻99Ω）的电流所产生的磁场进行了补偿，使霍尔器件U1始终处于检测零磁通的工作状态。

当主回路有一大电流Ip流过时，在导体周围产生相应的电磁场Hp，穿过磁场的磁力线被聚集环聚集，并作用于霍尔器件，霍尔器件U1产生电流信号输出；此电流信号经信号放大器U2（差分放大器）放大，输入至功率放大电路（由VT1、VT2构成的互补放大器），从而产生一个流经L1的补偿电流Is。

Metrix Vibration ST5484E 振动传感器数据手册说明书

ST5484E Seismic Velocity 4-20 mA TransmitterDatasheet2-Pin MIL Connector(Option D=4)The ST5484E is a self-contained seismic velocity transmitter that incorporates a piezoelectric accelerometer, signal integrator, RMS peak detector, and a 4-20 mA signal conditioner into a single package. It can be mounted directly on a machine case or bearing housing without intervening signal conditioning equipment. The amplitude of the integrated acceleration (velocity) signal is con -verted to a proportional 4-20 mA signal compatible with industrial process control instrumentation such as PLCs, DCSs, and SCADA systems that can provide trending and/or alarming capabilities for a simplified vibration monitoring strategy.When the flying lead or terminal block connector options are chosen, the transmitter does not need a separate environmental housing and can directly accept conduit. To reduce installed cost, it can be used with barriers for intrinsically safe installations, or wired directly to explosion-proof conduit fittings for explosion- proof installations.Need A Local Display?When continuous, local indication of vibra -tion levels is required at the transmitter, the Metrix ST5491E provides these capabilities.Its sensing and transmitter elements are similar to the ST5484E, but it includes a convenient 2½ digit LCD display in an integral conduit elbow and is rated for use in temperatures from -10o C to +70o C. Refer to Metrix datasheet 1004598 for ordering information and de -tailed specifications.A vibration transmitter may be appropriate in applications where a stand-alone monitoring system may not be warranted.The ST5484E handles general-purpose vibration measurements on a wide range of rotating and reciprocating machinery with ro -tative speeds between 120- and 6,000-rpm. Seismic measure -ments are suitable for machines with rolling-element bearings because shaft vibration in such machines is usually transmitted directly through the bearing to the bearing housing without sub -stantial damping or attenuation. Seismic transducers can also measure vibration that does not originate at the shaft, such as bearing-related wear and defects, footing/foundation problems, piping resonances that are coupled to the machine, etc.Why Measure Velocity?Acceleration and displacement levels are heavily influenced by the frequencies at which the vibration is occurring, while velocity levels are much less influenced. Thus, although acceleration,velocity, and displacement measurements are inter-related math -ematically, seismic velocity measurements tend to be more con -sistent over a wide range of frequencies than either displacement or acceleration. Consequently, broadband (sometimes called “overall” or “unfiltered”) velocity measurements are appropriate for monitoring many machines as a reliable indicator of damag -ing vibratory energy, with the notable exception of machines with fluid-film bearings, which are usually better addressed by shaft-observing proximity probes.Casing displacement is not a practical measurement to make directly and is typically just an integrated seismic velocity mea -surement. As such, the primary decision when selecting a seis -mic sensor will usually be whether to measure casing velocity or casing acceleration. As noted above, casing velocity will often be more appropriate because it tends to be a more reliable indicator of damaging vibratory energy over a broad frequency spectrum for low- to medium-speed machinery.Flying Leads(Option D=0, 1, 5, or 6) (2-wire shown; 4-wire also available)2-Pin Terminal Block(Option D=2)4-Pin Terminal Block(Option D=3)1180OVERVIEWAPPLICATIONSNote: Units sold with an explosion proof rating will in -clude a conduit elbow:8200-000 IEC for ATEX/IECEx/INMETRO/KOSHA/EAC8200-000 for CSAExplosion Proof Versionswith Option D≠4ST5484E Seismic Velocity 4-20 mA TransmitterDatasheetNOTE: For machines with fluid-film bearings, shaft- observing proximity probes will provide more effective vibration measurements than seismic transducers due to the rotor dynamics of the machine and the attenuation of vibratory energy through a fluid-film boundary. Accord -ingly, Metrix recommends and provides proximity probes and associated 4-20 mA transmitters or monitoring systems for such applications.For machines with rolling element bearings and running above 6,000 rpm, and/or where impulsive casing vibration occurs, acceleration may be a better measurement. In such situations, it is recommended that you consult witha Metrix sales professional who can review your application and assist with selection of the proper transducer type and associated transmitter or monitoring system.• RFI/EMI Immunity – Enhanced circuit design and installa -tion techniques aggressively filter out noise from common sources such as handheld radios•Excellent Moisture Resistance – The 2-pin MIL connec -tor version is hermetically sealed to provide an IP67-rated enclosure. Flying lead and terminal block versions are fully potted and rated to IP66 when installed with optional IEC conduit elbow• Hazardous Area Approvals – North American (CSA), Brazil -ian (INMETRO), and European (ATEX & IEC) approvals avail -able•Dynamic Signal Availability – 2-wire versions provide a 4-20 mA velocity- proportional signal for easy connection to PLCs, DCSs, and other plant control systems. Optional 4-wire ver -sions 1 also provide the raw acceleration signal (100 mV/g) for use with vibration data collectors and analyzers • Variety of Connection Options – Flying leads, terminal block, and MIL-type connectors available• Conduit-Ready 2 – Terminal block and flying lead options have conduit threads on top of sensor. No special housings are required for connection of conduit•Rugged, Industrial Design – Robust construction offers out -standing durability; built-in base and housing strain protec -tion helps ensure that over-torqueing sensor-to- machine and sensor-to-conduit connections won’t damage internals or body•High- and Low-Pass Filter Options – The ST5484E can be ordered with a wide variety of low- and high-pass filter options to precisely tailor the band over which vibration is measured•Polarity-Independent Wiring – Metrix patented IPT® tech -nology allows loop power to be connected without regard to voltage polarity, reducing field wiring errors and ensuring that the raw acceleration output 1 is not phase inverted • Multiple Mounting Options – Integral and removablemounting stud options available in both metric and English thread sizes; flat base mounting adapters are also available • Loop-Powered – Runs on nominal 24 V DC power supplied by the 4-20 mA current loop•Wide Supply Voltage Range – Accepts loop power voltages from 11 to 29.6 V DC (intrinsically safe) or 30.0 V DC (explosion proof & non-incendive)• RMS Amplitude Detection – Measures Root Mean Square (RMS) vibration amplitude. Options available for True RMS or scaled RMS (RMS x √2) for “derived peak”•Numerous Full Scale Ranges – The full scale ranges provid -ed in option AAA reflect frequently-ordered ranges; how -ever, many others (too numerous to list) are also available. Consult factory for applications requiring other full scale rangesNotes:1. Dynamic raw acceleration signal available with 4-wire versions only(ordering options D= 1 and D=3).2. Metrix recommends flexible (rather than solid) conduit when pos -sible. Solid conduit can introduce preload forces on the sensor andalter of the vibration response of the sensor.All specifications are at +25°C (+77°F) and +24 V DC supply voltage unless otherwise noted.FEATURESSPECIFICATIONSST5484E Seismic Velocity 4-20 mA TransmitterDatasheetST5484E Seismic Velocity 4-20 mA TransmitterDatasheetA A AB BCD -ST5484E- - -FE ORDERING INFORMATIONST5484E Seismic Velocity 4-20 mA TransmitterDatasheetNOTES:1. Smaller-diameter mounting studs are not able to withstand sus -tained ambient vibration levels above2.0 in/sec. Consult Table 2 for allowable combinations of A and B options.2. The ST5484E uses an RMS amplitude detection circuit. Full scaleranges in peak units use scaled RMS (i.e., RMS x √2). The “derived peak” measurements will equal true peak only under the special case of a pure sinusoid, not complex vibration signals.3. Hazardous Area Certifications are not compatible with all connec -tion types. Consult Table 3 for allowable combinations of C & D options.4. Some approvals require intrinsic safety barriers, others requireExplosion-Proof wiring practices. Refer to Table 4.5. Refer to the Accessories section of this document.

High- and Low-Pass filter corners for standard filters must beseparated by at least one octave (low-pass frequency must be at least twice the high-pass frequency). All combinations are allowed except E = 6 and F = 4, 5, or 6. Custom filters with closer separa -tion and/or different roll-offs may be available in some instances.Consult the factory if custom filters are required.Conduit elbows are used with flying leads and terminal block versions of the ST5484E transmitter. They are not compatible with MIL-connector versions of the transmitter. A variety of available configurations accommodate English and metric conduit thread sizes, hazardous area approvals, materials of construction, and IP ratings. Note that not all configurations are available with hazardous area approvals or IP ratings. Consult the ordering information below. For ST5484E’s that need an explosion proof (Ex d) rating, that are utiliz -ing flying leads, Option D=0, 1, 5, & 6, will have an attached 8200 conduit elbow and must be used with a certified junction box or other certified connection location. For ST5484E’s that need an explosion proof (Ex d) rating, utilizing integral terminal block, Option D=2 & 3, no junction box is necessary. Table 4 in the datasheet relates what hazardous area (Option C) is allowed per ST5484E Connection (Op -tion D).

MAX4172：高品质的高侧电流感应器说明书

General DescriptionThe MAX4172 is a low-cost, precision, high-side current-sense amplifier for portable PCs, telephones, and other systems where battery/DC power-line monitoring is critical. High-side power-line monitoring is especially useful in battery-powered systems, since it does not interfere with the battery charger’s ground path. Wide bandwidth and ground-sensing capability make the device suitable for closed-loop battery-charger and general-purpose current-source applications. The 0 to 32V input common-mode range is independent of the supply voltage, which ensures that current-sense feedback remains viable, even when connected to a battery in deep discharge.T o provide a high level of flexibility, the MAX4172 functions with an external sense resistor to set the range of load current to be monitored. It has a current output that can be converted to a ground-referred voltage with a single resistor, accommodating a wide range of battery voltages and currents.An open-collector power-good output (PG ) indicates when the supply voltage reaches an adequate level to guarantee proper operation of the current-sense amplifier. The MAX4172 operates with a 3.0V to 32V supply voltage, and is available in a space-saving, 8-pin μMAX ® or SO package.Applications●Portable PCs: Notebooks/Subnotebooks/Palmtops ●Battery-Powered/Portable Equipment●Closed-Loop Battery Chargers/Current Sources ●Smart-Battery Packs ●Portable/Cellular Phones●Portable Test/Measurement Systems●Energy Management SystemsBenefits and Features●Ideal for High-Side Monitoring• 3V to 32V Supply Operation• ±0.5% Typical Full-Scale Accuracy Over T emperature • High Accuracy +2V to +32V Common-Mode Range, Functional Down to 0V, Independent of Supply Voltage• 800kHz Bandwidth [V SENSE = 100mV (1C)]• 200kHz Bandwidth [V SENSE = 6.25mV (C/16)] ●Minimizes Board Space Requirements• μMAX and SO Packages19-1184; Rev 5; 12/20μMAX is a registered trademark of Maxim Integrated Products, Inc.Click here to ask about the production status of specific part numbers.+Denotes a lead(Pb)-free/RoHS-compliant package.Ordering InformationTypical Operating CircuitPin ConfigurationPART TEMP RANGE PIN-PACKAGE MAX4172ESA+-40°C to +85°C 8 SO MAX4172EUA+-40°C to +85°C 8 μMAX MAX4172GUA+-40°C to +105°C8 µMAXMAX4172Low-Cost, Precision, High-SideCurrent-Sense AmplifierV+, RS+, RS-, PG .................................................-0.3V to +36V OUT .............................................................-0.3V to (V+ + 0.3V)Differential Input Voltage, V RS+ - V RS- ..........................±700mV Current into Any Pin .........................................................±50mA Continuous Power Dissipation (T A = +70°C)SO (derate 5.88mW/°C above +70°C) ........................471mW μMAX (derate 4.10mW/°C above +70°C) ...................330mWOperating Temperature RangeMAX4172E_A .................................................-40°C to +85°C MAX4172G_A ...............................................-40°C to +105°C Storage Temperature Range ............................-65°C to +150°C Lead Temperature (soldering, 10s) .................................+300°C Soldering Temperature (reflow) .......................................+260°C(V+ = +3V to +32V; V RS+, V RS- = 0 to 32V; T A = T MIN to T MAX ; unless otherwise noted.

This feature not only allows the monitoring of current flow into a battery in deep discharge, but also enables high-side current sensing at voltages far in excess of the supply voltage (V+).The MAX4172 current-sense amplifier’s unique topology simplifies current monitoring and control. The MAX4172’s amplifier operates as shown in Figure 1. The battery/load current flows through the external sense resistor(R SENSE ), from the RS+ node to the RSnode. Current flows through R G1 and Q1, and into the current mirror, where it is multiplied by a factor of 50 before appearing at OUT.To analyze the circuit of Figure 1, assume that current flows from RS+ to RS-, and that OUT is connected to GND through a resistor. Since A1’s inverting input is high impedance, no current flows though R G2 (neglecting the input bias current), so A1’s negative input is equal to V SOURCE - (I LOAD x R SENSE ). A1’s open-loop gain forces its positive input to essentially the same voltage level as the negative input. Therefore, the drop across R G1 equalsPin DescriptionTypical Operating Characteristics (continued)5µs/divSTARTUP DELAYGNDV OUT 500mV/divV+2V/divGNDV SENSE = 100mVMAX4172-1010ms/divV+ to PG POWER-UP DELAYGNDPG 2V/divV+2V/divGND100kW PULLUP RESISTOR FROM PG TO +4VMAX4172-11PIN NAME FUNCTION1RS+Power connection to the external sense resistor.

A low level indicates that V+ is sufficient to power the MAX4172, and adequate time has passed for power-on transients to settle out.8V+Supply Voltage Input for the MAX4172Current-Sense AmplifierI LOAD x R SENSE. Then, since I RG1 flows through R G1, I RG1 x R G1 = I LOAD x R SENSE. The internal current mirror multiplies I RG1 by a factor of 50 to give I OUT = 50 x I RG1. Substituting I OUT/50 for I RG1, (I OUT/50) x R G1 = I LOAD x R SENSE, or:I OUT = 50 x I LOAD x (R SENSE/R G1)The internal current gain of 50 and the factory-trimmed resistor R G1 combine to result in the device’s transcon-ductance (G m) of 10mA/V. G m is defined as being equal to I OUT/(V RS+ - V RS-). Since (V RS+ - V RS-) = I LOAD x R SENSE, the output current (I OUT) can be calculated with the following formula:I OUT = G m x (V RS+ - V RS-) =(10mA/V) x (I LOAD x R SENSE)Current OutputThe output voltage equation for the MAX4172 is given below:V OUT = (G m) x (R SENSE x R OUT x I LOAD)where V OUT = the desired full-scale output voltage, I LOAD equals the full-scale current being sensed, R SENSE equals the current-sense resistor, R OUT equals the voltage-setting resistor, and G m equals the device’s transconductance (10mA/V).The full-scale output voltage range can be set by changing the R OUT resistor value, but the output voltage must be no greater than V+ - 1.2V. The above equation can be modified to determine the R OUT required for a particular full-scale range:R OUT = (V OUT)/(I LOAD x R SENSE x G m)OUT is a high-impedance current source that can be integrated by connecting it to a capacitive load.PG OutputThe PG output is an open-collector logic output that indicates the status of the MAX4172’s V+ power supply. A logic low on the PG output indicates that V+ is sufficient to power the MAX4172. This level is temperature dependent (see Typical Operating Characteristics graphs), and is typically 2.7V at room temperature. The internal PG comparator has a 100mV (typ) hysteresis to prevent possible oscillations caused by repeated toggling of the PG output, making the device ideal for power-management systems lacking soft-start capability. An internal delay (15μs, typ) in the PG comparator allows adequate time for power-on transients to settle out. The PG status indicator greatly simplifies the design of closed-loop systems by ensuring that the components in the control loop have sufficient voltage to operate correctly. Applications InformationSuggested Component Valuesfor Various ApplicationsThe Typical Operating Circuit is useful in a wide variety of applications. Table 1 shows suggested component values and indicates the resulting scale factors for various applications required to sense currents from 100mA to 10A.Adjust the R SENSE value to monitor higher/lower current levels. Select R SENSE using the guidelines and formulas in the following section.Figure 1. Functional DiagramCurrent-Sense AmplifierSense Resistor, R SENSEChoose R SENSE based on the following criteria:● Voltage Loss: A high R SENSE value causes the power-source voltage to degrade through IR loss. For minimal voltage loss, use the lowest R SENSE value.● Accuracy: A high R SENSE value allows lower currents to be measured more accurately. This is because offsets become less significant when the sense voltage is larger. For best performance, select R SENSE to provide approximately 100mV of sense voltage for the full-scale current in each application.● Efficiency and Power Dissipation: At high current levels, the I 2R losses in R SENSE can be significant. Take this into consideration when choosing the resistor value and its power dissipation (wattage) rating. Also, the sense resistor’s value might drift if it is allowed to heat up excessively.● Inductance: Keep inductance low if I SENSE has a large high-frequency component. Wire-wound resis-tors have the highest inductance, while metal film is somewhat better. Low-inductance metal-film resistors are also available. Instead of being spiral wrapped around a core, as in metal-film or wirewound resistors, they are a straight band of metal and are available in values under 1Ω.● Cost: If the cost of R SENSE is an issue, you might want to use an alternative solution, as shown in Figure 2. This solution uses the PCB traces to create a sense resistor. Because of the inaccuracies of the copper resistor, the full-scale current value must be adjusted with a potentiometer. Also, copper’s resistance temperature coefficient is fairly high (approximately 0.4%/°C).In Figure 2, assume that the load current to be measured is 10A, and that you have determined a 0.3-inchwide, 2-ounce copper to be appropriate. The resistivity of 0.1-inch-wide, 2-ounce (70μm thickness) copper is 30mΩ/ft. For 10A, you might want R SENSE = 5mΩ for a 50mV drop at full scale. This resistor requires about 2 inches of 0.1-inch-wide copper trace.Current-Sense Adjustment(Resistor Range, Output Adjust)Choose R OUT after selecting R SENSE . Choose R OUT to obtain the full-scale voltage you require, given the full-scale I OUT determined by R SENSE . OUT’s high impedance permits using R OUT values up to 200kΩ with minimal error. OUT’s load impedance (e.g., the input of an op amp or ADC) must be much greater than R OUT (e.g., 100 x R OUT ) to avoid degrading measurement accuracy.High-Current MeasurementThe MAX4172 can achieve high-current measurements by using low-value sense resistors, which can be paralleled to further increase the current-sense limit. As an alternative, PCB traces can be adjusted over a wide range.Figure 2. MAX4172 Connections Showing Use of PC BoardTable 1.

However, in high-current systems, large voltage drops can develop across the ground plane, which can add to or subtract from V OUT. Use a single-point star ground for the highest currentmeasurement accuracy. The MAX4172 requires no special bypassing and responds quickly to transient changes in line current. If the noise at OUT caused by these transients is a problem, you can place a 1μF capacitor at the OUT pin to ground. You can also place a large capacitor at the RS terminal (or load side of the MAX4172) to decouple the load, reducing the current transients. These capacitors are not required for MAX4172 operation or stability. The RS+ and RS- inputs can be filtered by placing a capacitor (e.g., 1μF) between them to average the sensed current.Chip Information SUBSTRATE CONNECTED TO GNDPackage InformationFor the latest package outline information and land patterns (footprints), go to /packages.

As magnetic fields can permeate non-magnetizable metals, they detect a permanent magnet attached to the piston through the aluminium cylinder wall.Weld-field immune permaprox sensors "freeze"the switching status when detecting a magnetic AC field (50…60 Hz). In this way, falseswitching operations are prevented during the welding process. When the AC field disappears,the sensors resume standard operation.TURCK Inc. | 3000 Campus Drive Minneapolis, MN 55441-2656 | Phone: 763-553-7300 | Application Support: 1-800-544-7769 | Fax 763-553-0708 | 2|3B I M -I K M -A P 6X 2-H 1141/S 34 W /K L I 3 | 07/22/2021 14-49 | t e c h n i c a l c h a n g e s r e s e r v e dTechnical dataMounting instructionsMounting instructions/DescriptionAccessoriesKLI169710Mounting bracket for mounting magnetic field sensors on tie-rodcylinders; cylinder diameter: 32…100mm; material: Die-cast ZincKLI369712Mounting bracket for mounting magnetic field sensors on tie-rodcylinders; cylinder diameter: 63…160mm; material: Die-cast ZincKLI56971802Mounting bracket for mounting magnetic field sensors on profile cylinders; cylinder diameter: 32…50mm; material: AluminumKLI66971805Mounting bracket for mounting magnetic field sensors on profilecylinders; cylinder diameter: 50…100mm; material: AluminumTURCK Inc. | 3000 Campus Drive Minneapolis, MN 55441-2656 | Phone: 763-553-7300 | Application Support: 1-800-544-7769 | Fax 763-553-0708 | 3|3B I M -I K M -A P 6X 2-H 1141/S 34 W /K L I 3 | 07/22/2021 14-49 | t e c h n i c a l c h a n g e s r e s e r v e dKLI76971810Mounting bracket for mounting magnetic field sensors on profilecylinders with external dovetail guide;cylinder diameter: 32…200 mm;material: AluminumKLI5Z 6971803Mounting bracket for mounting magnetic field sensors on tie-rod cylinders; cylinder diameter: 32…63mm; material: AluminumKLI6Z 6971806Mounting bracket for mounting magnetic field sensors on tie-rodcylinders; cylinder diameter: 50…125mm; material: Aluminum。

In the design of the TS1103, the input amplifier was reconfiguredfor fully differential input/output operation and a second low-threshold p-channel FET (M2) was added where the drain terminal of M2 is also connected to ROUT. Therefore, the behavior of the TS1103 for when V RS- > V RS+ is identical for when V RS+ > V RS-.Referring to the typical application circuit on Page 1, the inputs of the TS1103’s differential input/output amplifier are connected across an external RSENSE resistor that is used to measure current. At the non-inverting input of the TS1103 (the RS- terminal), the applied voltage is I LOAD x RSENSE. Since the RS- terminal is the non-inverting input of the internal op amp, op amp feedback action forces the inverting input of the internal op amp to the same potential (I LOAD x RSENSE). Therefore, the voltage drop across RSENSE (V SENSE = V RS+ - V RS-) and the voltage drop across RGAINA (at the RS+ terminal) are equal. Necessary for gain ratio match, both RGAINA and RGAINB are the same value.Since p-channel M1’s source is connected to the inverting input of the internal op amp and since the voltage drop across RGAINA is the same as theTS1103 Page 8TS1103 Rev. 1.0external V SENSE, op amp feedback action drives the gate of M1 such that M1’s drain-source current is equal to:I DS(M1)=V SENSE RGAINAorI DS(M1)=I LOAD x R SENSERGAINASince M1’s drain terminal is connected to ROUT, the output voltage of the TS1103 at the OUT terminal is, therefore;V OUT=I LOAD x R SENSE xR OUT RGAINAWhen the voltage at the RS- terminal is greater than the voltage at the RS+ terminal, the external VSENSE voltage drop is impressed upon RGAINB. The voltage drop across RGAINB is then converted into a current by M2 that then produces an output voltage across ROUT. In this design, when M1 is conducting current (V RS+> V RS-), the TS1103’s internal amplifier holds M2 OFF. When M2 is conducting current (V RS-> V RS+), the internal amplifier holds M1 OFF. In either case, the disabled FET does not contribute to the resultant output voltage.The current-sense amplifier’s gain accuracy is therefore the ratio match of ROUT to RGAIN[A/B]. For each of the four gain options available, Table 1 lists the values for ROUT and RGAIN[A/B]. The TS1103’s output stage is protected against input overdrive by use of an output current-limiting circuit of 3mA(typical) and a 7V internal clamp protection circuit.Table 1: Internal Gain Setting Resistors (Typical Values)The SIGN Comparator OutputAs shown in the TS1103’s block diagram, the design of the TS1103 incorporated one additional feature – an analog comparator the inputs of which monitor the internal amplifier’s differential output voltage. While the voltage at the TS1103’s OUT terminal indicates the magnitude of the load current, the TS1103’s SIGN output indicates the load current’s direction. The SIGN output is a logic high when M1 is conducting current (V RS+> V RS-). Alternatively, the SIGN output is a logic low when M2 is conducting current (V RS+< V RS-). The SIGN comparator’s transfer characteristic is illustrated in Figure 1. Unlike other current-sense amplifiers that implement a OUT/SIGN arrangement, the TS1103 exhibits no “dead zone” at I LOAD switchover.Figure 1: TS1103's SIGN Comparator TransferCharacteristic.SIGNPropagationDelay-msFigure 2: SIGN Comparator Propagation Delay vs V SENSE.1000.1101V SENSE (│V RS+ - V RS-│) - mV0.1 1 10 100TS1103TS1103 Rev. 1.0 Page 9The other attribute of the SIGN comparator’s behavior is its propagation delay as a function of applied V SENSE [(V RS+ - V RS-) or (V RS- - V RS+)]. As shown in Figure 2, the SIGN comparator’spropagation delay behavior is symmetric regardless of current-flow direction and is inversely proportional to V SENSE .APPLICATIONS INFORMATIONChoosing the Sense ResistorSelecting the optimal value for the external RSENSE is based on the following criteria and for each commentary follows:1) RSENSE Voltage Loss2) V OUT Swing vs. Applied Input Voltage at V RS+and Desired V SENSE 3) Total I LOAD Accuracy4) Circuit Efficiency and Power Dissipation 5) RSENSE Kelvin Connections1) RSENSE Voltage LossFor lowest IR power dissipation in RSENSE, the smallest usable resistor value for RSENSE should be selected.2) V OUT Swing vs. Applied Input Voltage at V RS+ and Desired V SENSEAs there is no separate power supply pin for the TS1103, the circuit draws its power from the voltage at its RS+ and RS- terminals. Therefore, the signal voltage at the OUT terminal is bounded by the minimum voltage applied at the RS+ terminal.Therefore,V OUT(max) = V RS+(min) - V SENSE(max) – V OH(max) andR SENSE < V OUT (max )GAIN × I LOAD (max )where the full-scale V SENSE should be less than V OUT(MAX)/GAIN at the application’s minimum RS+ terminal voltage. For best performance with a 3.6V power supply, RSENSE should be chosen to generate a V SENSE of: a) 120mV (for the 25V/V GAIN option), b) 60mV (for the 50V/V GAIN option), c) 30mV (for the 100V/V GAIN option), or d) 15mV (for the 200V/V GAIN option) at the full-scale I LOAD current in each application. For the case where the minimum power supply voltage is higher than 3.6V, each of the four full-scale V SENSE s above can be increased.3) Total Load Current Accuracy In the TS1103’s linear region where V OUT < V OUT(max), there are two specifications related to the circuit’s accuracy: a) the TS1103’s input offset voltage (V OS(max) = 200μV) and b) its gain error (GE(max) = 0.6%). An expression for the TS1103’s total error is given by:V OUT = [GAIN x (1 ± GE) x V SENSE ] ± (GAIN x V OS )A large value for RSENSE permits the use of smaller load currents to be measured more accurately because the effects of offset voltages are less significant when compared to larger VSENSE voltages. Due care though should be exercised as previously mentioned with large values of RSENSE.4) Circuit Efficiency and Power DissipationIR losses in RSENSE can be large especially at high load currents. It is important to select the smallest, usable RSENSE value to minimize power dissipation and to keep the physical size of RSENSE small. If the external RSENSE is allowed to dissipate significant power, then its inherent temperature coefficient may alter its design center value, thereby reducing load current measurement accuracy. Precisely because the TS1103’s input stage was designed to exhibit a very low input offset voltage, small RSENSE values can be used to reduce power dissipation and minimize local hot spots on the pcb.5) RSENSE Kelvin ConnectionsFor optimal V SENSE accuracy in the presence of large load currents, parasitic pcb track resistance should be minimized. Kelvin-sense pcb connections between RSENSE and the TS1103’s RS+ and RS- terminals are strongly recommended. The drawing in Figure 3 illustrates the connections between theTS1103Page 10TS1103 Rev. 1.0current-sense amplifier and the current-sense resistor. The pcb layout should be balanced and symmetrical to minimize wiring-induced errors. In addition, the pcb layout for RSENSE should include good thermal management techniques for optimal RSENSE power dissipation.6) RSENSE CompositionCurrent-shunt resistors are available in metal film, metal strip, and wire-wound constructions. Wire-wound current-shunt resistors are constructed with wire spirally wound onto a core. As a result, these types of current shunt resistors exhibit the largest self inductance. In applications where the load current contains high-frequency transients, metal film or metal strip current sense resistors are recommended.Internal Noise FilterIn power management and motor control applications, current-sense amplifiers are required to measure load currents accurately in the presence of both externally-generated differential and common-mode noise. An example of differential-mode noise that can appear at the inputs of a current-sense amplifier is high-frequency ripple. High-frequency ripple – whether injected into the circuit inductively or capacitively - can produce a differential-mode voltage drop across the external current-shunt resistor (RSENSE). An example of externally-generated, common-mode noise is the high-frequency output ripple of a switching regulator that can result in common-mode noise injection into both inputs of a current-sense amplifier.Even though the load current signal bandwidth is DC, the input stage of any current-sense amplifier can rectify unwanted, out-of-band noise that can result in an apparent error voltage at its output. This rectification of noise signals occurs because all amplifier input stages are constructed with transistors that can behave as high-frequency signal detectors in the same way pn-junction diodes were used as RF envelope detectors in early radio designs. Against common-mode injected noise, the amplifier’s internal common-mode rejection is usually sufficient.To counter the effects of externally-injected noise, it has always been good engineering practice to add external low-pass filters in series with the inputs of a current-sense amplifier. In the design of discrete current-sense amplifiers, resistors used in the external low-pass filters were incorporated into the circuit’s overall design so errors because of any input-bias current-generated offset voltage errors and gain errors were compensated.With the advent of monolithic current-sense amplifiers, like the TS1103, the addition of external low-pass filters in series with the current-sense amplifier’s inputs only introduces additional offset voltage and gain errors. To minimize or eliminate altogether the need for external low-pass filters and to maintain low input offset voltage and gain errors, the TS1103 incorporates a 50-kHz (typ), 2nd -order differential low-pass filter as shown in the TS1103’s Block Diagram.Output Filter CapacitorIf the TS1103 is part of a signal acquisition system where its OUT terminal is connected to the input of an ADC with an internal, switched-capacitor track-and-hold circuit, the internal track-and-hold’s sampling capacitor can cause voltage droop at V OUT . A 22nF to 100nF good-quality ceramic capacitor from the OUT terminal to GND forms a low-pass filter with the TS1103’s R OUT and should be used to minimize voltage droop (holding V OUT constant during the sample interval. Using a capacitor on the OUT terminal will also reduce the TS1103’s small-signal bandwidth as well as band-limiting amplifier noise.PC Board Layout and Power-Supply Bypassing For optimal circuit performance, the TS1103 should be in very close proximity to the external current-sense resistor and the pcb tracks from RSENSE to the RS+ and the RS- input terminals of the TS1103 should be short and symmetric. Also recommended are a ground plane and surface mount resistors and capacitors.Figure 3: Making PCB Connections to RSENSE.TS1103400 West Cesar Chavez, Austin, TX 78701TS1103 Rev. 1.0+1 (512) 416-8500 ▪ PACKAGE OUTLINE DRAWING6-Pin SOT23 Package Outline Drawing(N.B., Drawings are not to scale)Note:Dimension are exclusive of mold flash and gate burr.2.
