considerations and Application Circuits.1.0Design ConsiderationsThis section covers the following design considerations:1.Frequency and Phase Response Considerations2.Unity-Gain Pulse Response Considerations3.Input Bias Current Considerations1.1Frequency and Phase Response Considerations The relationship between open-loop frequency response and open-loop phase response determines the closed-loop stability performance(negative feedback).The open-loop phase response causes the feedback signal to shift towards becoming positive feedback,thus becoming unstable.The further the output phase angle is from the input phase angle,the more stable the negative feedback will operate.Phase Margin(φm)specifies this output-to-input phase relationship at the unity-gain crossover point.Zero degrees of phase-margin means that the input and output are completely in phase with each other and will sustain oscillation at the unity-gain frequency.The AC tables showφm for a no load condition.Butφm changes with load.The Gain and Phase margin vs Fre-quency plots in the curve section can be used to graphically determine theφm for various loaded conditions.To do this, examine the phase angle portion of the plot,find the phase margin point at the unity-gain frequency,and determine how far this point is from zero degree of phase-margin.The larger the phase-margin,the more stable the circuit operation. The bandwidth is also affected by load.The graphs of Figure 1and Figure2provide a quick look at how various loads af-fect theφm and the bandwidth of the LMV821/822/824family. These graphs show capacitive loads reducing bothφm and bandwidth,while resistive loads reduce the bandwidth but in-crease theφm.Notice how a600Ωresistor can be added in parallel with220picofarads capacitance,to increase theφm 20˚(approx.),but at the price of about a100kHz of band-width.Overall,the LMV821/822/824family provides good stability for loaded condition.1.2Unity Gain Pulse Response ConsiderationsA pull-up resistor is well suited for increasing unity-gain, pulse response stability.For example,a600Ωpull-up resis-tor reduces the overshoot voltage by about50%,when driv-ing a220pF load.Figure3shows how to implement the pull-up resistor for more pulse response stability.Higher capacitances can be driven by decreasing the value of the pull-up resistor,but its value shouldn’t be reduced be-yond the sinking capability of the part.An alternate approach is to use an isolation resistor as illustrated in Figure4. Figure5shows the resulting pulse response from a LMV824, while driving a10,000pF load through a20Ωisolation resistor.DS100128-60FIGURE1.Phase Margin vs Common Mode Voltage forVarious

to Drive HeavyCapacitive Loads 111.3Input Bias Current ConsiderationInput bias current (I B )can develop a somewhat significant offset voltage.This offset is primarily due to I B flowing through the negative feedback resistor,R F .For example,if I B is 90nA (max room)and R F is 100k Ω,then an offset of 9mV will be developed (V OS =I B x R F ).Using a compensation resis-tor (R C ),as shown in Figure 6,cancels out this affect.But the input offset current (I OS )will still contribute to an offset volt-age in the same manner -typically 0.05mV at room temp.2.0APPLICATION CIRCUITSThis section covers the following application circuits:1.Telephone-Line Transceiver2.“Simple”Mixer (Amplitude Modulator)3.Dual Amplifier Active Filters (DAAFs)•a.Low-Pass Filter (LPF)•b.High-Pass Filter (HPF)5.Tri-level Voltage Detector2.1Telephone-Line TransceiverThe telephone-line transceiver of Figure 7provides a full-duplexed connection through a PCMCIA,miniature trans-former.The differential configuration of receiver portion (UR),cancels reception from the transmitter portion (UT).Note that the input signals for the differential configuration of UR,are the transmit voltage (Vt)and Vt/2.This is because R match is chosen to match the coupled telephone-line imped-ance;therefore dividing Vt by two (assuming R1>>R match ).The differential configuration of UR has its resistors chosen to cancel the Vt and Vt/2inputs according to the following equation:Note that Cr is included for canceling out the inadequacies of the lossy,miniature transformer.Refer to application note AN-397for detailed explanation.2.2“Simple”Mixer (Amplitude Modulator)The mixer of Figure 8is simple and provides a unique form of amplitude modulation.Vi is the modulation frequency (F M ),while a +3V square-wave at the gate of Q1,induces a carrier frequency (F C ).Q1switches (toggles)U1between in-verting and non-inverting unity gain configurations.Offset-ting a sine wave above ground at Vi results in the oscillo-scope photo of Figure 9.The simple mixer can be applied to applications that utilize the Doppler Effect to measure the velocity of an object.The difference frequency is one of its output frequency compo-nents.This difference frequency magnitude (/F M -F C /)is the key factor for determining an object’s velocity per the Dop-pler Effect.If a signal is transmitted to a moving object,the reflected frequency will be a different frequency.This differ-ence in transmit and receive frequency is directly propor-tional to an object’s velocity.DS100128-54FIGURE 5.Pulse Response per

LMV822/24bring economy and performance to DAAFs.The low-pass and the high-pass filters of Figure10and Fig-ure11(respectively),offer one key feature:excellent sensi-tivity performance.Good sensitivity is when deviations incomponent values cause relatively small deviations in a fil-ter’s parameter such as cutoff frequency(Fc).Single ampli-fier active filters like the Sallen-Key provide relatively poorsensitivity performance that sometimes cause problems forhigh production runs;their parameters are much more likelyto deviate out of specification than a DAAF would.TheDAAFs of Figure10and Figure11are well suited for highvolume production.Table1provides sensitivity measurements for a10MΩloadcondition.The left column shows the passive componentsfor the3kHz low-pass DAAF.The third column shows thecomponents for the300Hz high-pass DAAF.Their respec-tive sensitivity measurements are shown to the right of eachcomponent column.Their values consists of the percentchange in cutoff frequency(Fc)divided by the percentchange in component value.The lower the sensitivity value,the better the performance.Each resistor value was changed by about10percent,andthis measured change was divided into the measuredchange in Fc.A positive or negative sign in front of the mea-sured value,represents the direction Fc changes relative tocomponents’direction of change.For example,a sensitivityvalue of negative1.2,means that for a1percent increase incomponent value,Fc decreases by1.2percent.Note that this information provides insight on how to finetune the cutoff frequency,if necessary.It should be alsonoted that R4and R5of each circuit also caused variations inDS100128-39FIGURE8.Amplitude Modulator CircuitffmodcarrierDS100128-40FIGURE9.Output signal per the Circuit of

to an op amp’s parameters -Gain and Bandwidth,in particular.The LMV822/24provide a large gain and wide bandwidth.And DAAFs make excel-lent use of these feature specifications.Single Amplifier versions require a large open-loop to closed-loop gain ratio -approximately 50to 1,at the Fc of the filter response.Figure 12shows an impressive photo-graph of a network analyzer measurement (hp3577A).The measurement was taken from a 300kHz version of Figure 10.At 300kHz,the open-loop to closed-loop gain ratio @Fc is about 5to 1.This is 10times lower than the 50to 1“rule of thumb”for Single Amplifier Active Filters.In addition to performance,DAAFs are relatively easy to de-sign and implement.The design equations for the low-pass and high-pass DAAFs are shown below.The first two equa-tion calculate the Fc and the circuit Quality Factor (Q)for the LPF (Figure 10).The second two equations calculate the Fc and Q for the HPF (Figure 11).To simplify the design process,certain components are set equal to each other.Refer to Figure 10and Figure 11.These equal component values help to simplify the design equa-tions as follows:To illustrate the design process/implementation,a 3kHz,Butterworth response,low-pass filter DAAF (Figure 10)is designed as follows:1.Choose C 1=C 3=C =1nF2.Choose R 4=R 5=1k Ω3.Calculate R a and R 2for the desired Fc as follows:4.Calculate R 3for the desired Q.The desired Q for a Butter-worth (Maximally Flat)response is 0.707(45degrees into the s-plane).R 3calculates as follows:Notice that R 3could also be calculated as 0.707of R a or R 2.The circuit was implemented and its cutoff frequency mea-sured.The cutoff frequency measured at 2.92kHz.The circuit also showed good repeatability.Ten different LMV822samples were placed in the circuit.The correspond-ing change in the cutoff frequency was less than a percent.DS100128-92FIGURE 12.300kHz,Low-Pass Filter,Butterworth Response as Measured by the HP3577A NetworkAnalyzer

TS823/824/825 SeriesMicroprocessor Supervisory Circuitwith Watchdog Timer & Manual ResetSOT-25General DescriptionThe TS823/824/825 family allows the user to customize the CPU monitoring function without any external components. The user has a large choice of reset voltage thresholds and output driver configurations, all of which are present ant the factory. Each wafer is trimmed to the customer’s specifications.These circuits will ignore fast negative going transients on Vdd. The state of the reset output is guaranteed to be correct down to 1V. After Vdd crosses above a factory present threshold, the TS823/824/825 assert a reset signal. After a predetermined time (the “reset” interval) the reset is deasserted. If Vdd ever drops below the threshold voltage a reset is asserted immediately. In addition to a supply monitoring function the TS823/824/825 also monitor transitions at the watchdog (WDI) input. If a logic transition does not occur at the WDI pin within a certain time interval (the “watchdog” interval) then a reset is asserted. The reset deasserts after the reset interval, as explained earlier.The TS823/824/825 can both assert a reset manually by pulling the MR input to ground, and the micro-power quiescent current make this family a natural for portable battery powered equipment.Ordering InformationNote: x is the threshold voltage type, option as A : 4.63V B : 4.38V D : 3.08V E : 2.93VF : 2.63VG : 2.32VH : 2.19VContact factory for additional voltage option Part No. Package Packing TS823CX5x RFSOT-25 3Kpcs / 7” Reel TS824CX5x RF SOT-25 3Kpcs / 7” Reel TS825CX5x RF SOT-25 3Kpcs / 7” Reel Features ● Precision monitoring of +3V, +3.3V and +5V powersupply voltage● Tight voltage threshold tolerance +/-1.5% ● Fully specified over temperature● 210mS min. power-on reset pulse width● 3uA(typ) supply current● Guaranteed reset valid to Vdd = +1V● Power supply transient immunity ● No external componentsApplications● Computers and Controllers ● Embedded Controllers ● Intelligent instruments ● Critical uP monitoring● Portable / Battery powered equipment ●Automotive SystemsPin DescriptionsFunctionTS823TS824TS825RESET (Active-Low)11 1 Ground2 2 2 Manual Reset3 -4 (RESET) (Active-High)- 3 3 Watchdog Input 4 4 - Supply Voltage (Vdd)555Absolute Maximum RatingParameterSymbolMaximumUnitSupply VoltageVdd 6.0 V Supply Voltage - RecommendedVdd 0.9 ~ 5 V Operating Junction Temperature Range T OP -40 ~ +125 o CStorage Temperature Range T STG -65 ~ +150oC Thermal ResistanceΘjc256oC/W Maximum Lead Temperature (260oC) T LEAD 10 STS823/824/825 SeriesMicroprocessor Supervisory Circuit with Watchdog Timer & Manual ResetElectrical Specifications (Ta = 25o C, unless otherwise noted)ParameterConditionsSymbolMinTypMaxUnitInput Supply VoltageVdd 1.0 -- 5.5 V Supply CurrentWDI and MRB unconnected Idd-- 3 10 uATS823/824/825CX5A 4.56 4.63 4.7 TS823/824/825CX5B 4.31 4.38 4.45 TS823/824/825CX5D 3.033.08 3.13 TS823/824/825CX5E 2.89 2.93 2.97 TS823/824/825CX5F 2.59 2.63 2.67 TS823/824/825CX5G 2.28 2.32 2.36Reset ThresholdTS823/824/825CX5HV TH2.152.19 2.23 VRESET Output Voltage Low Vdd<V TH(MIN), I SINK =1.2mA, V OL -- -- 0.5 V (RESET) Output Voltage High Vdd>VTH(MAX), I SOURCE =0.5mA V OH 0.8 Vdd -- -- V Vdd to Reset DelayVdd =V TH - 100mVT D1 -- 40 -- uS Reset Active Timeout Period Ta=-40o C ~+85oC T D2 140 210 280 mS Watchdog Timeout Period T WD 1120 1760 2400 mS WDI Pulse WidthT WDI 50 -- -- nS W DIIL -- -- 0.7 V WDI Input Threshold Vdd = V TH x 1.2 W DIIH 0.8 Vdd -- -- V W DI =0V I IL -15 -8 0.7 uA WDI Input Current W DI =Vdd = 5V I IH -- 8 15 uA M RIL -- -- 0.7 V MR Input Threshold Vdd=V TH x 1.2M RIH 0.8 Vdd -- -- V MR Pulse WidthT WMR 1 -- -- uS MR Noise Immunity Pulse width with no reset -- 100 -- nS MR to Reset Delay Vdd = V TH - 100mV T DMR -- 500 -- nS MR Pull Up Resistance80 -- 120 K Ω Input Supply VoltageTa=-40oC~+85oCV CC1.0--5.5VDetail DescriptionPin FunctionPin Name Pin Description Reset Active Low GND Ground (Reset)Active HighMRThis pin is active low. Pulling this pin low to forces a reset. After a low to high transition reset remains asserted for exactly one reset timeout period. This pin is internally pulled high. If this function is unused then float this pin or tie it to Vdd.WDIWatch Dog Input. Any transition on this pin will reset the Watch Dog timer. If this pin remains high or low for longer than the Watch Dog interval then a reset is asserted. Float or tri-state this pin to disable the Watch Dog feature.VddPositive power supply. A reset is asserted after this voltage drops below a predetermined level. AfterTS823/824/825 SeriesMicroprocessor Supervisory Circuitwith Watchdog Timer & Manual Reset Application InformationThe TS823/824/825 are designed to interface with the reset input of a microprocessor and to prevent CPU execution errors due to power up, power down, and other power supply errors. The TS823/824 also monitor the CPU health by checking for signal transitions form the CPU at the WDI input.Reset OutputActive low reset outputs are denoted as RESET, Active high reset output are denoted as (RESET),A reset will be asserted if any of three things happen:1. Vdd drops below the threshold (Vth)2. The MR pin is pulled low.3. The WDI pin does not detect a transition within the Watch Dog interval (TWD)The reset will remain asserted for the prescribed reset interval after:1. Vdd rises above the threshold (Vth)2. MR goes high3. The Watch Dog timer have timed out causing the reset to assert.Manual Reset InputThe TS823 and TS825 feature a manual reset feature (MR). A logic low on the MR pin asserts a reset. The reset remains asserted a long as the MR pin remains low. After the MR pin transitions to a high state the reset remains asserted for the prescribed reset interval (TD2). The MR pin is internally pulled up to Vdd by a 100KΩ resistor. It is internally de-bounced to reject switching transients.The MR pin is ESD protected by diodes connected to Vdd and Gnd. So the MR pin should never be driven higher than Vdd or lower than Gnd.Watchdog InputThe TS823 and TS824 are equipped with a watchdog input (WDI). If the microprocessor does not produce a valid logic edge at the watchdog input (WDI) within the prescribed watchdog interval (TWD) then a reset asserts. The reset remains asserted for the required reset interval (TD2). Ata the end of the reset interval the reset is deasserted and the watchdog interval timer starts again from zero.If the watchdog input is left unconnected or is connected to a tri-stated buffer the watchdog function is disabled. As soon as the WDI input is driven either low or high the watchdog function resumes with the watchdog timer set to zero. Watchdog Input CurrentThe watchdog input pin (WDI) typically sources/sinks 8uA when driven high or low. So from a power dissipation point of view the duty cycle of the waveform at WDI is unimportant. When the WDI pin is floating or tri-stated the power supply current fall to less than 3uA.Glitch RejectionThe TS823/824/825 family will reject negative going transients on the Vdd line to some extent. The smaller the duration of the transient the larger its amplitude may be without triggering a reset. The “Glitch Rejection” chart in the graphs section of this datasheet shows the relation between glitch amplitude and allowable glitch duration to avoid unintended resets.Accurate Output State at Low VddWith Vdd voltage on the order of the MOS transistor threshold (<1V) the outputs of the TS823/824/825 may become undefined. For parts with active low output RESET a resistor placed between RESET and Gnd on the order of 100KΩwill ensure that the RESET output stays low when Vdd is lower than the threshold voltage of the part. In a like manner a resistor on the order of 100KΩ when placed between (RESET) and Vdd will ensure parts with active high output (RESET) will remain high when Vdd is lower than the threshold voltage of the parts.TS823/824/825 Series Microprocessor Supervisory Circuitwith Watchdog Timer & Manual Reset Reset Timing DiagramReset Timing DiagramTS823/824/825 SeriesMicroprocessor Supervisory Circuit with Watchdog Timer & Manual ResetElectrical Characteristics CurveFigure 1.

The input is designed to survive sustained input voltage up to 30V to protect against hot plug overshoot and faulty charging adapters. Thermal limiting protects the SC824 from excessive power dissipation.The SC824 provides three modes of charging: adapter mode, USB low power mode, and USB high power mode. Adapter mode charges up to 1A with the charging adapter operating either in voltage regulation or in current limit to obtain the lowest possible power dissipation. A single current programming pin is used to program precharge current, termination current, and fast-charge current in fi xed proportions. The USB modes provide low and high power fast-charge currents. The two USB modes dynami-cally limit the charging load if necessary to automatically prevent overloading the USB Vbus supply.The SC824 provides a battery NTC thermistor interface to disable charging when the battery temperature exceeds programmed thresholds. An optional programmable multi-stage charge timer protects against a faulty battery, or terminates charging on timeout if the system load is too great to terminate charging on current. A 45 minute top-off period following termination ensures a fully charged battery. The monitor state restarts a charge cycle if the battery discharges after the charger has turned off .LoadV ADAPTERMODE SELECT CPU GPIOTypical Application CircuitPin Confi gurationMarking InformationOrdering InformationDevicePackageSC824ULTRT (1)(2)MLPD-UT-10 2×2SC824EVBEvaluation BoardNotes:(1) Available in tape and reel only.

This pin is protected against damage due to high voltage up to 30V.2VSYS System reference voltage supply — 4.6V reference used internally and externally by the NTC circuit. Must have a 1μF capacitor connected between VSYS and GND.3MODECharging mode selection (tri-level logical) input — Logical high selects USB high power mode, floating selects USB low power mode, ground selects adapter mode.4RTIMETimer setting pin — Connect a resistor between this pin and ground to set the time-out value of the CC mode timer. Connect to ground to disable the timer. Tie to VSYS to select the 3 hour CC timer using the internal oscilla-tor.5GND Ground6STAT1Status open drain output pin that is active low when charging is in progress, with or without a charging fault. When charging is complete, pin is released. See STATx Pin Truth Table.7STAT0Status open drain output pin that is pulled low when a valid charging adapter is connected and the voltage is greater than the UVLO level and less than the OVP level, and no charging fault is detected. Pin is released when the input is disconnected from a power supply, or to indicate a charging fault. See STATx Pin Truth Table.8 IPRGMCharging current programming pin — Connect a resistor from this pin to ground to program charge current. Pre-charge current (also USB low power mode fast-charge current) is 20% of IPRGM-programmed fast-charge current in all modes. The charging termination current threshold for all modes is 10% of the IPRGM programmed fast-charge current. If this pin is grounded, pin-short detection holds the SC824 in logical reset, with charging disabled.9BATCharger output — Connect to battery positive terminal.10EN_NTCBattery NTC thermistor connection pin — EN_NTC pin input voltage ranges are ratiometric with respect to the VSYS pin output voltage. The safe-to-charge battery temperature range is programmed with a resistor from the EN_NTC pin to the VSYS pin, and a battery pack NTC thermistor to ground; charging is suspended when theEN_NTC pin voltage is less than 30%, or greater than 75%, of V VSYS . When pulled down below 10% of V VSYS , charging is unconditionally disabled. When the level exceeds 95% of V VSYS , the battery is assumed to be disconnected and the device operates in No-Battery mode.T Thermal PadPad is for heatsinking purposes — The thermal pad is not connected internally. Connect exposed pad to ground plane using multiple vias.分销商库存信息: SEMTECHSC824ULTRT。

1/5s LOW T c: 50 ppm/°C MAXIMUM s 1.225V OUTPUT VOLTAGEs LOW OPERATING CURRENT : 45µA max @25°Cs HIGH PRECISION AT 25°C: ±1%s STABLE WHEN USED WITH CAPACITIVELOADSs INDUSTRIAL TEMPERATURE RANGE:-40 to +85°C DESCRIPTIONThe TS824 is a low power shunt voltage reference featuring a very low temperature coefficient of 50ppm/°C as a maximum value. Providing 1.225V output voltage, the TS824 operates over the industrial temperature range (-40 to +85°C). Ideal for battery-powered equipments where power conservation is critical, the TS824 is housed in a tiny SOT23-3 package allowing space saving. The TS824 is typically stable with any capacitive loads within the entire temperature range. The product is thus easy to use and the design simpli-fied.APPLICATIONs Instrumentation,s Data acquisition systems,s Portable, Battery powered equipments sPower managementORDER CODELT = Tiny Package (SOT23-3) - only available in Tape & Reel (LT)PIN CONNECTIONS (top view)VoltagePrecisionSOT23-3SOT23 Marking 1.225V 1%TS824ILT-1.2L251Single temperature range: -40 to +85°CTS824-1.2HIGH THERMAL STABILITYMICROPOWER SHUNT VOLTAGE REFERENCEMarch 2002TS824-1.22/5ABSOLUTE MAXIMUM RATINGSOPERATING CONDITIONSELECTRICAL CHARACTERISTICS (note 3)T amb = 25°C (unless otherwise specified)Symbol ParameterValue Unit I K Reverse Breakdown Current20mA I F Forward Current10mA P D Power Dissipation (note 1)SOT23-3360mW T Std Storage Temperature -65 to +150°C TJ Junction Temperature+150°C T Lead Lead Temperature (soldering, 10 seconds)+260°C ESDHuman Body Model (HBM) (note 2)2kV Machine Model (MM) (note 2)200VNote 1: The maximum power dissipation must be derated at high temperature. It can be calculated using T JMAX (maximum junction tem-perature), R THJA (Thermal resistance junction to ambient) and T A (Ambient temperature). The maximum power dissipation formula at any temperature is P DMAX = (T JMAX - T A ) / R THJA. R THJA is 340°C/W for the SOT23-3 package.Note 2: The Human Body Model (HBM) is defined as a 100pF capacitor discharge through a 1.5k Ω resistor into each pin. The Machine Mode (MM) is defined as a 200pF capacitor discharge directly into each pins.Symbol ParameterValue Unit I min Minimum Operating Current 40µA I max Maximum Operating Current12mA T operOperating Free Air Temperature Range-40 to +85°CSymbol ParameterTest ConditionMin.Typ.Max.Unit V KReverse Breakdown VoltageI K = 100µA1.213 1.2251.237V Reverse Breakdown Voltage Tolerance I K = 100µA-40°C < T amb < +85°C -12-16+12+16mV I KMIN Minimum Operating Current T amb = 25°C4045µA -40°C < T amb < +85°C 50∆V K /∆TAverage Temperature Coefficient (note 4)I K = 100µA50ppm/°C∆V K /∆I K Reverse Breakdown Voltage Change with Operating Current RangeI KMIN < I K < 1mA-40°C < T amb < +85°C 0.311.5mV1mA < I K < 12mA -40°C < T amb < +85°C 2.5810R KA Static Impedance ∆I K = I KMIN to 1mA -40°C < T amb < +85°C 0.311.5Ω∆I K = 1mA to 12mA -40°C < T amb < +85°C 0.250.70.9K VH Long Term Stability I K = 100µA, t = 1000hrs 120ppm E NWide Band NoiseI K = 100µA100Hz < f < 10kHz200nV/√HzNote 3: Limits are 100% production tested at 25°C.
