Before a system initializes, the power supply must stabi-lize. Using the ADM181x series ensures that there are typically 150 ms for the power supply to stabilize before the system is reset and safe system initialization begins.The ADM181x series of microprocessor reset circuits are avail-able in low cost, space-saving SOT-23 packages.ADM1810–ADM1813/ADM1815–ADM1818–SPECIFICATIONS(T A = –40؇C to +85؇C unless otherwise noted)Parameter Min Typ Max Units Test Conditions/NoteSUPPLYVoltage 1.2 5.5VCurrent3040µA(ADM1810/ADM1811/ADM1813)V CC < 5.5 V, RST Output Open3040µA(ADM1812) V CC < 5.5 V2835µA(ADM1815/ADM1816/ADM1817/ADM1818)V CC < 5.5 V, RST Output OpenOUTPUT CURRENT8mA@ 0.4 V, V CC≥ 2.7 V*350µA(ADM1810/ADM1812/ADM1815/ADM1817)@ 2.4 V, V CC≥ 2.7 VOUTPUT VOLTAGE V CC – 0.5V CC – 0.1V(ADM1810/ADM1812/ADM1815/ADM1817)@ 0 µA to 500 µAV CC TRIP-POINTADM1810-5, ADM1810-10, ADM1810-15/ADM1811/ADM1812/ADM1813-5 4.50 4.62 4.75V(5%)ADM1811/ADM1812/ADM1813-10 4.25 4.35 4.49V(10%)ADM1811/ADM1812/ADM1813-15 4.00 4.13 4.24V(15%)ADM1815/ADM1816/ADM1817/ADM1818-5 2.98 3.06 3.15V(5%)ADM1815/ADM1816/ADM1817/ADM1818-10 2.80 2.88 2.97V(10%)ADM1815/ADM1816/ADM1817/ADM1818-20 2.47 2.55 2.64V(20%)INTERNAL PULL-UP RESISTORADM1811/ADM1813/ADM1816/ADM1818 3.5 5.57.5kΩOUTPUT CAPACITANCE10pFRESET ACTIVE TIME100150300msV CC DETECT TO RSTFalling510µs(ADM1810/ADM1811/ADM1812/ADM1813)715µs(ADM1815/ADM1816/ADM1817/ADM1818) Rising100150300ms t R = 5 µsPUSH-BUTTON DETECT TO RST1µs(ADM1813/ADM1818)PUSH-BUTTON RESET100150300ms(ADM1818) 2.7 V ≤ V CC≤ 3.3 V100150300ms(ADM1813)NOTES*For ADM181x-20, V CC = V CCTP, sink current reduces to 8 mA.Specifications subject to change without notice.REV. 0–2–REV. 0ADM1810–ADM1813/ADM1815–ADM1818–3–ORDERING GUIDENOTESRL7 or REEL7 are in reels of 3000 parts.

Pressing this switch will pull the reset output low. If the push-button reset button pulls the RST output low for a period greater than 1 µs, then, when the reset button releases the RST line to float high, the RST line will stay low for a further 150 ms typical.Figure 4.Push-Button Reset Timing DiagramThe ADM1818 range has options which allow the user to monitor 3.3 V supplies with 10% and 20% tolerance options.While the ADM1813 range has options which allow the user to monitor 5 V supplies with 5%, 10% and a 15% tolerance options.ADM1810, ADM1812, ADM1815 AND ADM1817The ADM1812 is a 5 V low cost voltage monitor with an active high push-pull output. The ADM1812 supports 5%, 10% and15% tolerances. The ADM1810 is similar to the ADM1812,except that the ADM1810 has an active low push-pull output.The ADM1817 is 3.3 V voltage monitor with an active high push-pull output. The ADM1817 supports 5%, 10% and 20%tolerances. The ADM1815 is similar to the ADM1817, except that the ADM1815 has an active low push-pull output.The ADM1810/ADM1812/ADM1815/ADM1817 can be con-nected directly to most microprocessor-reset inputs without the need for external components.Figure 5.ADM1810/ADM1812/ADM1815/ADM1817Typical ApplicationOUTLINE DIMENSIONSDimensions shown in inches and (mm).3-Lead Plastic Surface Mount Package (SOT-23)(RT-3)ADM1811 AND ADM1816The ADM1811 is a low cost voltage monitor with an open drain output.

MAXIM MAX4561 MAX4568 MAX4569 数据手册
General DescriptionThe MAX4561/MAX4568/MAX4569 are low-voltage,ESD-protected analog switches. The normally open (NO) and normally closed (NC) inputs are protected against ±15kV electrostatic discharge (ESD) without latchup or damage, and the COM input is protected against 2.5kV ESD.These switches operate from a single +1.8V to +12V supply. The 70Ωat 5V (120Ωat 3V) on-resistance is matched between channels to 2Ωmax, and is flat (4Ωmax) over the specified signal range. The switches can handle Rail-to-Rail ® analog signals. Off-leakage current is only 0.5nA at +25°C and 5nA at +85°C. The digital input has +0.8V to +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply. The MAX4561 is a single-pole/double-throw (SPDT) switch. The MAX4568 NO and MAX4569 NC are single-pole/single-throw (SPST) switches.The MAX4561 is available in a 6-pin SOT23 package,and the MAX4568/MAX4569 are available in 5-pin SOT23 packages.________________________ApplicationsHigh-ESD Environments Battery-Powered Systems Audio and Video Signal Routing Low-Voltage Data-Acquisition Systems Sample-and-Hold Circuits Communications CircuitsFeatureso ESD-Protected NO, NC±15kV—Human Body Model±15kV—IEC 1000-4-2, Air-Gap Discharge ±8kV—IEC 1000-4-2, Contact Discharge o Guaranteed On-Resistance70Ω+5V Supply120Ωwith Single +3V Supplyo On-Resistance Match Between Channels (2Ωmax)o Low On-Resistance Flatness: 4Ωmax o Guaranteed Low Leakage Currents0.5nA Off-Leakage (at T A = +25°C)0.5nA On-Leakage (at T A = +25°C)o Guaranteed Break-Before-Make at 5ns(MAX4561 only)o Rail-to-Rail Signal Handling Capabilityo TTL/CMOS-Logic Compatible with +5V Supplies o Industry Standard Pin-OutsMAX4561 Pin Compatible with MAX4544MAX4568/MAX4569 Pin Compatible with MAX4514/MAX4515MAX4561/MAX4568/MAX4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches________________________________________________________________Maxim Integrated Products 1Pin Configurations/Functional Diagrams/Truth Tables19-1714; Rev 0; 4/00For free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.Ordering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.查询MAX4561EUT-T供应商M A X 4561/M A X 4568/M A X 4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS —Single +5V Supply(V+ = +4.5V to +5.5V, V IH = +2.4V, V IL = +0.8V, T A = T MIN to T MAX , unless otherwise specified.

To accomplish this, bidirectional SCRs are included on-chip between these terminals. When the voltages at these terminals go Beyond-the-Rails ™,the corresponding SCR turns on in a few nanoseconds and bypasses the surge safely to ground. This method is superior to using diode clamps to the supplies because unless the supplies are very carefully decou-pled through low-ESR capacitors, the ESD current through the diode clamp could cause a significant spike in the supplies. This may damage or compromise the reliability of any other chip powered by those same supplies.There are diodes from NC/NO to the supplies in addi-tion to the SCRs. A resistance in series with each of these diodes limits the current into the supplies during an ESD strike. The diodes protect these terminals from overvoltages that are not a result of ESD strikes. These diodes also protect the device from improper power-supply sequencing.Once the SCR turns on because of an ESD strike, it remains on until the current through it falls below its “holding current.” The holding current is typically 110mA in the positive direction (current flowing into the NC/NO terminal) at room temperature (see SCR Holding Current vs.Temperature in the Typical Operating Characteristics ). Design the system so that any sources connected to NC/NO are current-limited to a value below the holding current to ensure the SCR turns off when the ESD event is finished and normal operation resumes. Also, remember that the holding current varies significantly with temperature. The worst case is at +85°C when the holding currents drop to 70mA. Since this is a typical number to guarantee turn-off of the SCRs under all conditions, the sources con-nected to these terminals should be current-limited to no more than half this value. When the SCR is latched,the voltage across it is approximately 3V. The supply voltages do not affect the holding current appreciably.The sources connected to the COM side of the switches need not be current limited since the switches turn off internally when the corresponding SCR(s) latch.Even though most of the ESD current flows to GND through the SCRs, a small portion of it goes into V+.Therefore, it is a good idea to bypass the V+ with 0.1µF capacitors directly to the ground plane.ESD protection can be tested in various ways. Inputs are characterized for protection to the following:•±15kV using the Human Body Model•±8kV using the Contact Discharge method speci-fied in IEC 1000-4-2 (formerly IEC 801-2)•±15kV using the Air-Gap Discharge method speci-fied in IEC 1000-4-2 (formerly IEC 801-2)ESD Test ConditionsContact Maxim Integrated Products for a reliability report that documents test setup, methodology, and results.Human Body ModelFigure 6 shows the Human Body Model, and Figure 7shows the waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which can be dis-charged into the test device through a 1.5k Ωresistor.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifi-cally refer to integrated circuits. The MAX4561 enables the design of equipment that meets Level 4 (the highest level) of IEC 1000-4-2, without additional ESD protec-tion components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak cur-rent in IEC 1000-4-2. Because series resistance is lower in the IEC 1000-4-2 ESD test model (Figure 8), the ESD withstand voltage measured to this standard is generally lower than that measured using the Human Body Model.Figure 9 shows the current waveform for the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.The Air-Gap test involves approaching the device with a charged probe. The Contact Discharge method connects the probe to the device before the probe is energized.Chip InformationPROCESS: CMOSBeyond-the-Rails is a trademark of Maxim Integrated Products.TRANSISTOR COUNT: 69(MAX4561)39(MAX4568/MAX4569)M A X 4561/M A X 4568/M A X 4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches 8_______________________________________________________________________________________Figure 1.

NCP1618A驱动的500W宽范围前端调节器评估板用户手册说明书
EVBUM2716/D 500 W, Wide-Mains,NCP1618A-driven Evaluation Board User's ManualIntroductionThe NCP1618A is an innovative multimode power factor controller [1]. The circuit naturally transitions from one operation mode (CCM,CrM or DCM) to another depending on the switching period duration so that the efficiency is optimized over the line/load range. In very light−load conditions, the circuit enters the soft−SKIP mode for minimized losses. Housed in a SO−9 package, the circuit further incorporates the features necessary for building robust and compact PFC stages, with few external components.The evaluation board is a 500 W wide−mains PFC stage.EVB ELECTRICAL SPECIFICATIONSDescriptionValue Units Input Voltage Range90−265V rms Line Frequency Range 45 to 66Hz Output Power500W Minimum Output Load Current 13mA Maximum Output Load Current1300mA Load Conditions For Efficiency Measurements (10%, 20%,..)10−100%Minimum Efficiency Over the Line/Load Range 94%Minimum PF Over The Line Range At Full Load95%Hold−Up Time (the output voltage remaining above 300 V)> 20ms Peak−To−Peak Low Frequency Output Ripple< 8%Note that the evaluation board does not need an external source to power the NCP1618A V CC . A charge pump is implemented on the board which typically provides V CC with a 23−V voltage.EVAL BOARD USER’S MANUALTHE BOARDFigure 1. The Wide−Mains, 500 W PFC StageAPPLICATION SCHEMATICPower SectionFigure 2. Power Section of the Application Schematic90−265 VrmsFigure 2 shows the power section of the application schematic. Charge pump (R 1, C 11, D Z1) provides the V CC voltage using an auxiliary winding of the PFC choke. Two ON Semiconductor FCPF165N65 MOSFETS (Q 1a and Q 1b ) are paralleled [2]. A Silicon Carbide Schottky diode (SiC) FFSPF0865A from ON Semiconductor is used as the boost diode [3]. An NTC is placed in series with the bulk capacitor C 4 to limit inrush currents when the PFC stage is plugged in. MOSFET Q 2 (FCA76N60 − 600 V , 36 m Ω,TO−3P MOSFET from ON Semiconductor [4]) is implemented to bypass the NTC when the bulk capacitor is charged. Practically, the drive voltage and a V CC charge pump output are applied to Q 2 gate so that Q 2 is on and the NTC bypassed as soon as the PFC stage is in operation. The evaluation board supports the use of a totem pole (Q 3, Q 4)to shorten the MOSFET transitions. However, if the pnp transistor (Q 4) is implemented to speed−up the turning off event, in this application, npn transistor Q 3 is not used (only its base−emitter junction is used as a diode for turning on current).Control SectionFigure 3. Control Section of the Application SchematicPin 5 of the NCP1618 is designed to monitor a signal from an auxiliary winding for detecting the core reset when this voltage drops to zero. This function ensures valley turn on in discontinuous and critical conduction modes (DCM and CrM). This pin can also be used to detect an over−voltage condition of the bulk voltage, hence offering a redundant OVP protection (OVP2). However, as detailed in [5] direct sensing of the bulk voltage for OVP2 may cause too much a power dissipation when an ultra−low standby consumption is targeted. That is why this board instead uses the auxiliary winding voltage to reconstruct a voltage representative of the bulk voltage. More specifically, charge pump R2, C10 and D5 of Figure 2 provides a signal representative of the drain−source voltage of the MOSFET (N*V DS), where N is the turns ratio (auxiliary winding number of turns / primary winding number of turns). This voltage biases the ZCD circuitry and as it is equal to (N*V BULK) during the demagnetization phase, it is sensed for OVP2. Components R5, C7 and D9 clamps reconstructed (N*V DS) signal to prevent that when the circuit starts or restarts operation after an interruption, an incorrect initial value of the C10 voltage causes OVP2 spurious tripping. See [5] for more details.Circuitry for Soft−SKIP TestingFigure 4. Circuitry for Soft−SKIP Mode TestingS1Manual switchThe NCP1618A is designed to enter the soft−SKIP mode at very light load. Soft−SKIP minimizes losses by forcing a very low frequency burst−mode of operation. First, the circuit charges the output voltage to 103% of its nominal voltage and at that moment, enters a deep idle mode where no DRV pulses are generated and all non−necessary circuitries are turned off so that the circuit consumption is reduced to a minimum (250 m A typically). The circuit wakes up and restarts a new active burst cycle when the output voltage has dropped to 98% of its nominal level. In other words, as illustrated by Figure 17a, the output voltage swings between 103% and 98% of its nominal value. The NCP1618A can be externally forced to enter the soft−SKIP mode by grounding the V M pin or applying negative pulses on the pfcOK pin (refer to [1] for more details). In the absence of a downstream converter, the circuit of Figure 4can be used to provide the soft−SKIP signal. A square−wave signal varying between about 0 and an upper voltage of 5 to 15 V should be applied to the SKIP_control2 input of the board. According to the position of manual switch S 1, either the V M or the pfcOK pin will be used for controlling the soft−SKIP mode.Important Remark:Proposed circuitry was designed to illustrate the NCP1618 operation. It should not be re−used in practical applications as is unless appropriate verifications are made to check that it can meet reliability and safety requirements and comply with relevant norms. In particular, the inrush management circuitry may not be re−used if risks exist that the NTC is not properly shorted when the PFC stage starts switching. If the NTC is not shorted, the V OUT voltage will be the sum of the bulk capacitor voltage plus the voltage produced by the inductor current across the NTC (V C4 + (R NTC * I L )) and in this case, too high a (R NTC * I L ) voltage can be destructive for the application. It must be also noted that the inrush management circuitry increases the current loop when the boost stage fuels the bulk capacitor,making the layout less optimal for very high−speed switching operation, particularly with high t RR boost diodes.TYPICAL WAVEFORMSFigure 5 shows the line current at 115 V rms and at below different load levels:•At full load, the NCP1618 operates in CCM.•At 50% of the load, the system operates in critical conduction mode•At 40% of the load, the 130 kHz frequency clamp starts to trip (Frequency−clamped critical conduction mode)leading to critical conduction mode operation at the top of the sinusoid and valley−2 operation near the line zero crossing as illustrated by Figure 6.•At 20% load, the NCP1618 frequency foldback makesthe PFC stage operate at nearly 30 kHz. Note that the circuit continues turning on at the valley and that the number of valleys depends on the line instantaneous voltage. For instance, the number of skipped valleys is high at the top of the sinusoid where the resonant period is short while turn on in the second valley is obtained at the line zero crossing where the resonant period is long. See Figure 7. However, the NCP1618always turns on at the valley as long as valleys are detectable.Figure 5.

After a 30−mn warm−up time at full load, the load is decreased from1.30 A down to 0.13 A by 0.13−A steps. The measure is made after 5 mn of operation at the operating point under test.Figure 8. Efficiency vs. LoadThe efficiency remains above 94% from 10% to 100% of the load at the 4 tested line levels (90 V rms, 115 V rms,230V rms and 265 V rms).•Power Factor and THDPower factor and THD are measured over the load range.Practically, the load current is swept starting from 1300 mA to 130 mA with 130 mA steps.Figure 9. PF and THD versus Loada)Power factor (PF)b)Total harmonic distortion (THD)On the 20% to 100% load range, the power factor remains higher than 0.9 and the THD well below 20% at the four tested line levels.Startup SequencesWhen the board is plugged in, the circuit first turns on the internal high−voltage start−up current source to charge up the VCC capacitor. When V CC reaches V CC (on ) (17 Vtypically), operation can begin and the PFC stage starts to deliver energy. When the bulk capacitor is charged to 98%of its nominal voltage, the pfcOK pin turns high to enable the downstream converter. As indicated in the data sheet, a 100m F V CC capacitor is typically charged from 0 to V CC (on )in about 215 ms. The total V CC capacitance of our board being 220 m F, we can hence expect the PFC stage to start about 470 ms after it is plugged in.Figure 10. Startup Sequence at Full Load, Low Linea)General view b)Magnified viewFigure 10 shows a start−up sequence done at full load (1.3A) and at the lowest line level (90 V), the V CC capacitor being discharged when the board is plugged in. As illustrated by Figure 10a, the total time necessary to have pfcOK high from PFC stage plug−in is nearly 590 ms (about 420 ms to raise V CC and 170 ms to charge the output capacitor). Magnified view of Figure 10b shows that it takes less than a line cycle to reach the full input current capability.Note that two rising slopes can be seen on the plot of Figure 10a during the V CC charge phase. This is because the NCP1618 startup current is limited to 1 mA (typically) until the V CC voltage exceeds about 0.8 V . This feature prevents the internal high−voltage current source from overheating if the V CC pin happens to be accidentally grounded. When this first sequence is completed, the NCP1618 sources the nominal charge current of 12 mA typically.Figure 11. Startup Sequence at No Load, Low Line (90 V rms)a)General view b)Magnified viewHowever, in normal operation, the PFC stage starts up with no load since the downstream converter is normally disabled until pfcOK gets high. Figure 11a shows that in this practical condition, the total start−up time is significantly less than 500 ms: the V CC still takes about 420 ms and the bulk capacitor is charged within 60 ms.TYPICAL BEHAVIOR AND WAVEFORMSAbrupt Line VariationsThe circuit detects the line range. Practically, the high−line mode is set when the HV pin voltage exceeds 236V (typically) and recovers the low−line mode when theHV pin voltage remains less than 222 V for more than 25 ms (typical values). More practically, these voltage levels corresponds to line rms values of 167 V and 157 V respectively.Figure 12. High−line DetectionFigure 13. 90 V rms to 265 V rmsLine Step at Full LoadThe line range detection circuit optimizes the operation for universal (wide input mains) applications. Practically, in “high−line”:•The regulation bandwidth is divided by 4•The power expression defining the threshold below which frequency foldback is engaged is changed (see data sheet [1]).Figure 13 shows a low− to high−line transition at full load (I out = 1.3 A). This abrupt line change causes a voltage increase well−contained by the over−voltage protection.Figure 14 details a high− to low−line transition at full load.The circuit moderately reacts to the abrupt line change during the 25 ms necessary for low−line detection. After this delay, the NCP1618 sharply reacts and effectively limits the output voltage decay. Practically, the output voltage remains above 320 V .Figure 14. 265 V rms to 90 V rms Line Drop at Full Loada)General view b)Magnified viewI LINEV outV inI LINEV outV in320 VLoad StepsIn essence, PFC stages are slow systems. Thus, the output voltage of PFC stages may exhibit excessive over− and under−shoots because of abrupt load or input voltage variations (e.g. at start−up). The NCP1618 incorporates a fast line / load compensation to avoid such large output voltage variations. Practically, the circuit monitors the output voltage and limits possible deviations with respect to the regulation nominal voltage (V out ,nom ). More specifically,the NCP1618:•Disables the drive to stop delivering power when the output voltage exceeds the over voltage protection level (105% of V out ,nom ) and until V out has decayed back to 103% of V out ,nom (typical values).•Drastically speeds−up the regulation loop (DynamicResponse Enhancer) when the output voltage goes below 95.5 % of V out ,nom .To illustrate these functions, every 500 ms, the load is abruptly changed from 0.13 A to 1.30 A (respectively 10%and 100% of the full load) and vice versa, with 2 A/m s edges.Figure 15 shows the resulting output voltage under the load changes at 115 V rms. We can see that the NCP1618 is able to maintain the output voltage above 350 V when the load is abruptly raised from 10% to 100% (Figure 15a) and below about 410 V when the load is suddenly 90% reduced (Figure 15b).Figure 15. 10% to 100% Load Steps at 115 V rmsa)Rising load step b)Falling load stepI LINEV outV M pin voltageI LINEV outV M pin voltageThe same test is made at 230 V rms. Again as illustrated by Figure 16, the output voltage remains within a narrow range (between about 360 and 411 V).Figure 16. 10% to 100% Load Steps at 230 V rmsa)Rising load step b)Falling load stepI LINEV outV M pin voltageI LINEV outV M pin voltageThe V M pin voltage is shown in Figure 15 and Figure 16as it is indicative of the operation mode. It is a constant dc voltage in FCCrM mode (2.50 V) and during an operation interruption caused by the over−voltage protection (3.75 V)while the V M pin voltage is a rectified sine−wave in CCM.Soft−SKIP ModeThe NCP1618 is designed to be externally forced to enter the soft−SKIP mode by grounding the V M pin or applying negative pulses on the pfcOK pin. When in soft−SKIP mode,the circuit charges the output voltage to 103% of its nominalvoltage and at that moment, enters a deep idle mode where no DRV pulses are generated and all non−necessary circuitries are turned off so that the circuit consumption is reduced to a minimum (250 m A typically). The circuit wakes up when the output voltage has decayed down to 98% of its nominal level and restarts a new active burst cycle. In other words, as illustrated by Figure 17a, the output voltage swings between 103% and 98% of its nominal value.Magnified view of Figure 17b shows the active part of the burst. It illustrates that for best efficiency, the PFC stage operates at low frequency with valley switching.Figure 17. Soft−Skip Operation (115 V, 1% Load)a)General view b)Magnified viewLine−Sag TestsTests can be made which consist of rapidly and repeatedly plug and unplug the power supply. If no specific function is implemented, a huge current can take place when the power supply is reconnected.The NCP1618 detects short drops/interruptions of the mains to prevent an excessive stress when the line recovers.Practically, such line−sag situations are detected when the input voltage remains below 100 V for 25 ms or more (typical values) and in such cases, CCM mode is disabled and a soft−stop sequence starts. Soft stop is the gradualdown−to−zero discharge of the control signal to smoothly stop operation.When the line recovers, the circuit resets the BUV timer.It is because a line−sag event is likely to cause a BUV (bulk under−voltage) detection. When a BUV fault is detected, no restart is normally possible until the BUV timer (500 ms typically) has elapsed. However, if the BUV protection trips during a line−sag sequence, operation resumes as soon as the line recovers. Also, the NCP1618 interrupts the soft−stop discharge, grounds the control signal and charges V CC to its startup level (V CC (on ) = 17 V) if below for a clean start−up [1].Figure 18. Line Short Drops to 50 V rmsa)20−ms line sag (115 V rms, full load)b)50−ms line sag (115 V rms, full load)I LINEV outV inV pfcOKI LINEV outV inV pfcOKFigure 18a shows the case of a very short line sag (20 ms)while the circuit is operating at 115 V rms, full load. It is too short to trip the line−sag protection. Figure 18b shows a longer line sag situation (50 ms). In this case, we can see that after 25 ms, soft−stop is engaged and that after 37.5 ms, the BUV protection trips as attested by the pfcOK grounding.Operation resumes as soon as the line is back without waiting for the BUV timer being elapsed.Hold−Up TimeHold−up time tests are made at 90 V , full load. In the Figure 19a case, the line is interrupted for 20 ms. In this situation, the output voltage drops to 310 V which is well above the bulk under−voltage level (V out ,BUV = 280 V). In turn, pfcOK remains high and keeps enabling the downstream converter which loads the PFC stage.In the Figure 19b case, the line interruption is extended to 50 ms (test still made at 90 V , full load). This test enables to confirm the BUV level (about 280 V) which is reached after about the first 24 ms of line absence. This is the moment when due to the bulk under−voltage tripping (BUV), the pfcOK pin is grounded to disable the downstream converter.The two plots of Figure 19 also show that when the output voltage decays, so does the pfcOK voltage (when it is not grounded). Actually, when in high state, the pfcOK voltage is proportional to the output voltage to provide the downstream converter not only with an enable/disable signal but also with a signal representative of the output voltage for feedforward.Figure 19.

Connection sheet included withtransformer. See Product Resources for Download.Supplied with two neoprene rubber insulating pads, one metal centering washer and allmounting hardware (except the 1,500 VA size).1,500 VA size - is supplied with a potted center for extra strength.Minimum 8" long flexible leadsManufactured using Class B (130 degree C) materials.Hi-Pot test of 4,000VAC RMS between primary & secondaryUL recognized to UL506 (XPTQ2.Guide) UL file #E207860CSA certified to C22.2 #66 - CSA file #209651CE compliant to IEC 61558-2-4This series replaces our older 182 Toroid Series.Note about Inrush Current:Due to the superior magnetic properties of Toroidal transformers they will be susceptibleto high magnetizing current when initially energized, only limited by the low DC resistanceof the primary winding. Depending on where you are in the AC cycle when thetransformer is energized dictates the chances of overloading the supply circuit. This iswhy the transformer may sometimes energize without a problem and other times it willblow the fuse or trip the circuit breaker. The duration of this overload is rarely longer thana half of a cycle. Therefore, you should consider using a slow-blow fuse, time delayedcircuit breaker or other form of soft start circuitry for the supply line when using these highefficient Toroidal transformers.Gallery1182K615********************Dual12.41%Open A 1182L630************6V @ 5A Dual11.70%Open B 1182N650*********************Dual12.60%Open C 1182Q680**********************Dual9.70%Open D 1182H915**********************Dual11.42%Open A 1182K930*********************Dual12.80%Open B 1182M950*********************Dual13.20%Open C 1182N980*********************Dual10.50%Open D 1182Q9120**********************Dual9.00%Open E 1182K1230*********************Dual11.70%Open B 1182L1250**********************Dual12.60%Open C 1182M1280**********************Dual9.70%Open D 1182P1212024V C.T. @ 5A12V @ 10A Dual7.70%Open E 1182Q12160***********************Dual7.70%Open F 1182S12225***********************Dual7.20%Open G 1182T12300*************12V @ 25A Dual7.10%Open H 1182W121000**********************Dual 2.20%Open L-1 1182J153030V C.T. @ 1A15V @ 2A Dual12.30%Open B 1182K1550**********************Dual13.00%Open C 1182M1580**********************Dual10.20%Open D 1182N1512030V C.T. @ 4A15V @ 8A Dual8.50%Open E 1182P15160***********************Dual7.00%Open F 1182H15225************15V @ 15A Dual7.20%Open G 1182S1530030V C.T. @ 10A15V @ 20A Dual 5.00%Open H 1182F1815***********************Dual11.7%Open A 1182H1830**********************Dual12.20%Open B 1182J1850**********************Dual13.80%Open C 1182L1880**********************Dual10.50%Open D 1182M18120**********************Dual7.70%Open E 1182N18160**********************Dual7.70%Open F 1182G18225**********************Dual7.30%Open G 1182G2230**********************Dual12.60%Open B 1182J2250**********************Dual14.20%Open C 1182L2280**********************Dual10.40%Open D 1182M22120**********************Dual8.40%Open E1182N22160**********************Dual8.40%Open F 1182P22225***********************Dual 6.40%Open G 1182S24500************************Dual 5.10%Open I 1182T24625************************Dual 3.30%Open J 1182U24750************************Dual 3.60%Open L 1182V241000**********************Dual 2.20%Open L 1182K3080**********************Dual9.70%Open D 1182L3012060V C.T. @ 2A30V @ 4A Dual7.70%Open E 1182M30160**********************Dual7.70%Open F 1182F30225*********************Dual 6.30%Open G 1182P3030060V C.T. @ 5A30V @ 10A Dual 6.10%Open H 1182R30500***********************Dual 4.80%Open I 1182S30625************************Dual 4.10%Open J 1182T30750*************30V @ 25A Dual 3.10%Open K 1182T30P750*************30V @ 25A Dual 3.10%Potted K1182T601500120V C.T. @12.50A60V @ 25A Dual 2.91%Open M1182U301000**********************Dual 2.20%Open L 1182V40P1500**********************Dual 3.70%Potted MPart No.VAVAC Secondary (RMS)Dual or Single% Voltage Toroid Dim.

18号试验指测试标准
18号试验指是用于模拟儿童是否会触及电器设备中的危险部件的测试工具。
其测试标准主要包括以下几个方面：
1. 尺寸和形状：18号试验指的尺寸和形状需要符合相关标准，例如GB/T 16482图12等。
这些标准规定了试验指的长度、直径、倒圆角、节距等参数，以确保试验指能够代表儿童的手指尺寸和形状。
2. 材料和质地：18号试验指的材料和质地需要具有一定的硬度、韧性和耐
磨性，以确保在测试过程中不会因为材料的原因而影响测试结果。
3. 测试方法和程序：在测试过程中，需要按照规定的测试方法和程序进行操作。
例如，试验指需要按照规定的方向和角度插入设备的开口，测试过程中需要记录插入的深度和阻力等参数。
4. 结果判定：根据测试结果，判断电器设备是否符合标准要求。
一般来说，如果试验指能够顺利插入设备的开口，并且没有明显的阻力或异常现象，则认为设备符合标准要求；反之，则认为设备不符合标准要求。
需要注意的是，不同的国家和地区可能会有不同的测试标准和要求，因此在实际应用中需要根据具体的标准和要求进行测试和判断。
同时，由于试验指测试涉及到人身安全问题，因此测试人员需要经过专业培训并具备相应的资质和经验，以确保测试结果的准确性和可靠性。
MAX6018 精确、低电压、低掉电、微电压电压参考说明书
MAX6018AEUR16+ T MAX6018AEUR12+TMAX6018AEUR18+TMAX6018AEUR21+TMAX6018BEUR16+TGeneral DescriptionThe MAX6018 is a precision, low-voltage, low-dropout, micropower voltage reference in a SOT23 package. This three-terminal reference operates with an input voltage from (V OUT + 200mV) to 5.5V, and is available with output voltage options of 1.2V, 1.6V, 1.8V, and 2.048VThe MAX6018 voltage reference consumes less than 5μA (max) of supply current and can source and sink up to 1mA of load current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, devices in the MAX6018 family offer a supply current that is virtually independent of supply voltage (with only 0.1μA/V variation with supply voltage) and do not require an external resistor. The MAX6018 has initial accuracies of 0.2% (A grade) and 0.4% (B grade) and temperature drift of 50ppm/°C (max). The low-dropout voltage and the ultra-low, supply voltage-independent supply current make this device ideal for two-cell alkaline, end-of-life, battery-monitoring systems. The MAX6018 is available in a tiny 3-pin SOT23 package.Applications●Two-Cell, Battery-Operated Systems ●Battery-Operated Equipment ●Hand-Held Equipment ●Data-Acquisition Systems●Industrial and Process-Control SystemsBenefits and Features●Ultra-Low Supply Current: 5μA (max) ● 1.6V Output from 1.8V Input ●Ultra-Small, 3-Pin SOT23 Package ●Initial Accuracy: ±0.2% (max)●Low Temperature Drift: 50ppm/°C (max) ●200mV Dropout Voltage●Load Regulation (1mA Source): 700μV/mA (max) ●Line Regulation (V OUT + 200mV) to 5.5V: 250μV/V(max) ●Four Output Voltage Options: 1.2V, 1.6V,1.8V,2.048VPARTTEMP RANGE PIN-PACKAGE TOP MARK MAX6018AEUR12+T -40°C to +85°C 3 SOT23-3FZJH MAX6018BEUR12+T -40°C to +85°C 3 SOT23-3FZJI MAX6018AEUR16+T -40°C to +85°C 3 SOT23-3FZJJ MAX6018BEUR16+T -40°C to +85°C 3 SOT23-3FZJK MAX6018AEUR18+T -40°C to +85°C 3 SOT23-3FZJL MAX6018BEUR18+T -40°C to +85°C 3 SOT23-3FZJM MAX6018AEUR21+T -40°C to +85°C 3 SOT23-3FZJN MAX6018BEUR21+T-40°C to +85°C3 SOT23-3FZJOPARTOUTPUT VOLTAGE (V)INITIAL ACCURACY (%)MAX6018AEUR12 1.263±0.2MAX6018BEUR12 1.263±0.4MAX6018AEUR16 1.600±0.2MAX6018BEUR16 1.600±0.4MAX6018AEUR18 1.800±0.2MAX6018BEUR18 1.800±0.4MAX6018AEUR21 2.048±0.2MAX6018BEUR212.048±0.4MAX6018Precision, Micropower, 1.8V Supply, Low-Dropout, SOT23 Voltage ReferenceTypical Application CircuitPin ConfigurationOrdering InformationSelector Guide(Voltages Referenced to GND)V IN ...........................................................................-0.3V to +6V Output Short-Circuit Duration to GND or V IN............Continuous Continuous Power Dissipation (T A = +70°C)3-Pin SOT23 (derate 4.0mW/°C above +70°C) ..........320mW Operating Temperature Range ...........................-40°C to +85°C Junction Temperature ......................................................+150°C Storage Temperature Range ............................-65°C to +150°C Lead Temperature (soldering, 10s) .................................+300°C(V IN = 1.8V; C OUT = 47nF, I OUT = 0; T A = T MIN to T MAX, unless otherwise noted.

This three-terminal reference operates with an input voltage from (V OUT + 200mV) to 5.5V, and is available with output voltage options of 1.2V, 1.6V, 1.8V, and 2.048V. These devices can source up to 1mA with <200mV of dropout voltage, making them attractive for use in low-voltage applications.Applications InformationOutput/Load CapacitanceThese devices require a minimum of 100pF load to maintain output stability.They remain stable for capacitive loads as high as 1μF. In applications where the load or the supply can experience step changes, a larger output capacitor reduces the amount of overshoot (or undershoot) and assists the circuit’s transient response. Otherwise, applications may not need more than 100pF.Supply CurrentThe 5μA maximum supply current varies only 0.1μA/V with the supply voltage.When the supply voltage is below the minimum-specified input voltage (as during turn-on), the devices can draw up to 20μA beyond the nominal supply current. The input voltage source must be capable of providing this current to ensure reliable turn-on.Turn-On TimeThese devices typically turn on and settle to within 0.1% of their final value in 200μs. The turn-on time can increase up to 1ms with the device operating at the minimum dropout voltage and the maximum load.PIN NAME FUNCTION1INSupply Voltage Input.

Since the minimum input voltage is 2.5V, this specification is only meaningful when V OUT(NOM)> 2.5V. For V OUT(NOM)between 2.5V and 3.5V, use the following equations: Typical Dropout = -93mV/V ✕V OUT(NOM)+ 445mV;Guaranteed Maximum Dropout = -137mV/V ✕V OUT(NOM)+7004mV. For V OUT(NOM)> 3.5V, Typical Dropout = 120mV;Maximum Dropout = 220mV.Typical Operating Characteristics(V IN = (V OUT + 500mV) or +2.5V, whichever is greater; SHDN = IN, C IN = 1µF, C OUT = 3.3µF, T A = +25°C, unless otherwise noted.)5025125100751501752252002500 1.0 1.50.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5GROUND PIN CURRENT vs. INPUT VOLTAGEINPUT VOLTAGE (V)G R O U N D P I N C U R R E N T (μA )4070558513014511510016000.20.30.40.50.10.60.70.80.9 1.0LOAD CURRENT (A)G R O U N D P I N C U R R E N T (μA )GROUND PIN CURRENT vs. LOAD CURRENT110130120150140160170-4010-15356085TEMPERATURE (°C)G R O U N D P I N C U R R E N T (μA )GROUND PIN CURRENT vs. TEMPERATUREM A X 1818500mA Low-DropoutLinear Regulator in SOT234_______________________________________________________________________________________Typical Operating Characteristics (continued)(V IN = (V OUT + 500mV) or +2.5V, whichever is greater; SHDN = IN, C IN = 1µF, C OUT = 3.3µF, T A = +25°C, unless otherwise noted.)060301209015018000.20.10.30.40.5LOAD CURRENT (A)D R O P O U T V O L T A GE (m V )DROPOUT VOLTAGE vs. LOAD CURRENT-3.0-2.0-2.5-1.5-1.0-0.500.51.01.52.02.53.0LOAD CURRENT (A)O U T P U T V O L T A G E A C C U R A C Y (%)0.20.30.40.10.50.60.70.90.8 1.0OUTPUT VOLTAGE ACCURACYvs. LOAD CURRENT-3.0-2.0-2.5-1.5-1.0-0.500.51.01.52.02.53.0-40-1510356085TEMPERATURE (°C)O U T P U T V O L T A G E A C C U R A C Y (%)OUTPUT VOLTAGE ACCURACYvs. TEMPERATUREPOWER-SUPPLY REJECTION RATIOvs. FREQUENCY8002010P S R R (d B )40305060700.010.11101001000FREQUENCY (kHz)LINE TRANSIENTMAX1818 toc08V INV OUT2.5V 10m V /d i v3.5V 100μs/div500m V /d i vLOAD-TRANSIENT RESPONSEMAX1818 toc09I OUTV OUT500mA 100mA20m V /d i v40μs/divV IN = 3.3V V OUT = 2.5V LOAD-TRANSIENT RESPONSENEAR DROPOUTMAX1818 toc10V O U T 100m V /d i v200m A 0I O U T10μs/div V IN = V OUT + 100mV V OUT = 3.3VPOWER-ON RESETMAX1818 toc11V INV POKV OUT2V/div10ms/divMAX1818500mA Low-DropoutLinear Regulator in SOT23_______________________________________________________________________________________5SHUTDOWN WAVEFORMMAX1818 toc12POK SHUTDOWN VOLTAGEV OUT02V/div200μs/div1.001.011.021.031.041.051.061.071.081.091.101.112.53.03.54.04.55.05.5SHORT-CIRCUIT CURRENT LIMITvs. SUPPLY VOLTAGESUPPLY VOLTAGE (V)S H O R T -C I R C U I T C U R R E N T L I M I T (A )The MAX1818 is a low-dropout, low-quiescent-current linear regulator designed primarily for battery-powered applications. The device supplies loads up to 500mA and is available with preset output voltages. As illustrat-ed in Figure 1, the MAX1818 consists of a 1.25V refer-ence, error amplifier, P-channel pass transistor, and internal feedback voltage-divider.The 1.25V reference is connected to the error amplifier,which compares this reference with the feedback volt-age and amplifies the difference. If the feedback volt-age is lower than the reference voltage, thevoltage. If the feedback voltage is too high, the pass-transistor gate is pulled up, allowing less current to pass to the output.The output voltage is fed back through either an inter-nal resistive divider connected to OUT or an external resistor network connected to SE T. The Dual Mode comparator examines V SET and selects the feedback path. If V SET is below 50mV, the internal feedback path is used and the output is regulated to the factory-preset voltage.Pin DescriptionTypical Operating Characteristics (continued)(V IN = (V OUT + 500mV) or +2.5V, whichever is greater; SHDN = IN, C IN = 1µF, C OUT = 3.3µF, T A = +25°C, unless otherwise noted.)M A X 1818500mA Low-DropoutLinear Regulator in SOT236_______________________________________________________________________________________Additional blocks include an output current limiter, ther-mal sensor, and shutdown logic.Internal P-Channel Pass TransistorThe MAX1818 features a 0.25ΩP-channel MOSFE T pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSFETs require no base drive,which reduces quiescent current. PNP-based regula-tors also waste considerable current in dropout when the pass transistor saturates, and use high base-drive currents under large loads. The MAX1818 does not suf-fer from these problems and consumes only 125µA of quiescent current under heavy loads as well as in dropout.Output Voltage SelectionThe MAX1818’s Dual Mode operation allows operation in either a preset voltage mode or an adjustable mode.Connect SE T to GND to select the preset output volt-age. The two-digit part number suffix identifies the out-put voltage (see Selector Guide). For example, the MAX1818EUT33 has a preset 3.3V output voltage.The output voltage may also be adjusted by connecting a voltage-divider from OUT to SE T to GND (Figure 2).Select R2 in the 25k Ωto 100k Ωrange. Calculate R1with the following equation:R1 = R2 [(V OUT / V SET ) – 1]where V SET = 1.25V, and V OUT may range from 1.25V to 5.0V.ShutdownPull SHDN low to enter shutdown. During shutdown, the output is disconnected from the input and supply cur-rent drops to 0.1µA. When in shutdown, POK pulls low and OUT is high impedance. The capacitance and load at OUT determine the rate at which V OUT decays.SHDN can be pulled as high as 6V, regardless of the input and output voltage.Figure 1. Functional DiagramPOK OutputThe power OK (POK) output pulls low when OUT is less than 93% of the nominal regulation voltage. Once OUT exceeds 93% of the nominal voltage, POK goes high impedance. POK is an open-drain N-channel output. To obtain a voltage output, connect a pullup resistor from POK to OUT. A 100k Ωresistor works well for most appli-cations. POK can be used as a power-okay (POK) signal to a microcontroller (µC), or drive an external LED to indi-cate power failure. When the MAX1818 is shut down,POK is held low independent of the output voltage. If unused, leave POK grounded or unconnected.Current LimitThe MAX1818 monitors and controls the pass transis-tor’s gate voltage, limiting the output current to 0.8A (typ). This current limit doubles when the output voltage is within 4% of the nominal value to improve perfor-mance with large load transients.Thermal Overload ProtectionThermal overload protection limits total power dissipa-tion in the MAX1818. When the junction temperature exceeds T J = +170°C, a thermal sensor turns off the pass transistor, allowing the IC to cool. The thermal sensor turns the pass transistor on again after the junc-tion temperature cools by 20°C, resulting in a pulsed output during continuous thermal overload conditions.Thermal overload protection protects the MAX1818 in the event of fault conditions. For continuous operation,do not exceed the absolute maximum junction-temper-ature rating of T J = +150°C.Operating Region and Power DissipationThe MAX1818’s maximum power dissipation depends on the thermal resistance of the IC package and circuit board, the temperature difference between the die junction and ambient air, and the rate of air flow. The power dissipated in the device is P = I OUT ×(V IN -V OUT ). The maximum allowed power dissipation is 800mW at T A = +70°C or:P MAX = (T J(MAX)- T A ) / ( θJC + θCA )where T J - T A is the temperature difference between the MAX1818 die junction and the surrounding air, θJC is the thermal resistance of the junction to the case,and θCA is the thermal resistance from the case through the PC board, copper traces, and other materi-als to the surrounding air. For best heatsinking, the copper area should be equally shared between the IN,OUT, and GND pins.The MAX1818 delivers up to 0.5A RMS and operates with input voltages up to +5.5V, but not simultaneously.High output currents can only be sustained when input-output differential voltages are low, as shown in Figure 3.MAX1818500mA Low-DropoutLinear Regulator in SOT23_______________________________________________________________________________________7Figure 2. Adjustable Output Using External Feedback ResistorsApplications InformationCapacitor Selection andRegulator StabilityCapacitors are required at the MAX1818’s input and output for stable operation over the full temperature range and with load currents up to 500mA. Connect a 1µF capacitor between IN and ground and a 3.3µF low-E SR capacitor between OUT and ground. For output voltages less than 2V, use a 4.7µF low-E SR output capacitor. The input capacitor (C IN ) lowers the source impedance of the input supply. Reduce noise and improve load-transient response, stability, and power-supply rejection by using larger output capacitors, such as 10µF.The output capacitor’s (C OUT ) equivalent series resis-tance (ESR) affects stability and output noise. Use out-put capacitors with an E SR of 0.1Ωor less to ensure stability and optimum transient response. Surface-mount ceramic capacitors have very low E SR and are commonly available in values up to 10µF. Connect C IN and C OUT as close to the MAX1818 as possible to mini-mize the impact of PC board trace inductance.Noise, PSRR, and Transient ResponseThe MAX1818 is designed to operate with low dropout voltages and low quiescent currents in battery-powered systems while still maintaining good noise, transient response, and AC rejection. See the T ypical Operating Characteristics for a plot of power-supply rejection ratio (PSRR) versus frequency. When operating from noisy sources, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors and through passive filtering techniques.The MAX1818 load-transient response (see T ypical Operating Characteristics ) shows two components of the output response: a DC shift from the output imped-ance due to the load current change, and the transient response. A typical transient response for a step change in the load current from 100mA to 500mA is 8mV. Increasing the output capacitor’s value and decreasing the ESR attenuates the overshoot.Input-Output (Dropout) VoltageA regulator’s minimum input-to-output voltage differen-tial (dropout voltage) determines the lowest usable sup-ply voltage. In battery-powered systems, this determines the useful end-of-life battery voltage.Because the MAX1818 uses a P-channel MOSFET pass transistor, its dropout voltage is a function of drain-to-source on-resistance (R DS(ON)) multiplied by the load current (see Typical Operating Characteristics ).V DROPOUT = V IN - V OUT = R DS(ON)× I OUTThe MAX1818 ground current remains below 150µA in dropout.M A X 18188_______________________________________________________________________________________500mA Low-DropoutLinear Regulator in SOT23Selector GuideChip InformationTRANSISTOR COUNT: 845Package InformationFor the latest package outline information and land patterns, go to /packages .MAX1818500mA Low-DropoutLinear Regulator in SOT23Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.
