The signals are arranged in functional groups according to their associated interface.The “n” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When “n” is not present before the signal name, the signal is asserted at the high voltage level.The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a signal is active, independent of whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inactive.5.1 Pin DescriptionsTable 5.2 USB2244/2244i 36-Pin QFN Pin DescriptionsNAMESYMBOL36-PIN QFNBUFFER TYPEDESCRIPTIONSECURE DIGITAL INTERFACESD DataSD_D[7:0]781020232545I/O12PUThe bi-directional signals should have weak pull-up resistors.

Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off.In addition, voltage transients on the AC power line may appear on the DC output. When this possibility exists, it is suggested that a clamp circuit be used.PARAMETER SYMBOL MIN MAXUNITS COMMENTSStorage Temperature T A-55150°C LeadTemperature 325°C Soldering < 10 seconds3.3V supply voltage V DD33, V DDA33-0.5 4.0V Voltage on USB+ and USB- pins -0.5(3.3V supply voltage + 2) ≤ 6VVoltage on GPIO10-0.5V DD33 + 0.3VWhen internal power FET operation of this pin is enabled, this pin may be simultaneously shorted to ground or anyvoltage up to 3.63V indefinitely, without damage to the device as long as V DD33 and V DDA33 are less than 3.63V and T A is less than 70o C.Voltage on any signal pin -0.5V DD33 + 0.3V Voltage on XTAL1 -0.5 4.0V Voltage on XTAL2-0.5V DD18 + 0.3VFigure 7.1 Supply Rise Time Model7.2 Recommended Operating ConditionsNote 7.3A 3.3V regulator with an output tolerance of 1% must be used if the output of the internal power FET’s must support a 5% tolerance.PARAMETERSYMBOLMINMAXUNITSCOMMENTSOperating Temperature Commercial Part Industrial Part T A T A 0-407085°C °C 3.3V supply voltage V DD33, V DDA33 3.0 3.6V (Note 7.3)3.3V supply rise time tRT0400μs Voltage onUSB+ and USB- pins-0.35.5VIf any 3.3V supply voltage drops below 3.0V, then the MAX becomes:(3.3V supply voltage) + 0.5 ≤ 5.5Voltage on any signal pin-0.3V DD33V Voltage on XTAL1 -0.3V DDA33V Voltage on XTAL2-0.3V DD18V7.3 DC Electrical CharacteristicsPARAMETER SYMBOL MIN TYP MAX UNITS COMMENTS I, IPU, IPD Type Input BufferLow Input Level High Input Level Pull DownPull Up V ILIV IHIPDPU2.072580.8VVμAμATTL LevelsIS Type Input BufferLow Input Level High Input Level HysteresisV ILIV IHIV HYSI2.04200.8VVmVTTL LevelsICLK Input BufferLow Input Level High Input Level Input Leakage V ILCKV IHCKI IL1.4-100.5+10VVμA VIN = 0 to V DD33Input Leakage (All I and IS buffers)Low Input Leakage High Input Leakage I ILI IH-10-10+10+10μAμAV IN = 0V IN = V DD33O12 Type BufferLow Output Level High Output Level Output Leakage V OLV OHI OLV DD33- 0.4-100.4+10VVμAI OL = 12mA @V DD33= 3.3VI OH = -12mA @V DD33= 3.3VV IN = 0 to V DD33(Note7.4)Note 7.4Output leakage is measured with the current pins in high impedance.Note 7.5See The USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics Note 7.6RBIAS is a 3.3V tolerant analog pin.Note 7.7Output current range is controlled by program software, software disables FET during short circuit condition.Note 7.8The assignment of each Integrated Card Power FET to a designated Card Connector is controlled by both firmware and the specific board implementation.

and bus-oriented receivers and transmitters.Together with the ’BCT2240 devices and SN74BCT2241, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable (OE) inputs, and complementary OE and OE inputs. These devices feature high fan-out and improved fan-in.To ensure the high-impedance state during power up or power down, OE should be tied to V CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.The outputs, which are designed to source or sink up to 12 mA, include 33-Ω series resistors to reduce overshoot and undershoot.ORDERING INFORMATIONT APACKAGE †ORDERABLE PART NUMBER TOP-SIDE MARKING PDIP − NTube SN74BCT2244N SN74BCT2244N C to 70SOIC DW Tube SN74BCT2244DW 0°C to 70°CSOIC − DW Tape and reel SN74BCT2244DWR BCT2244SOP − NS Tape and reel SN74BCT2244NSR BCT2244CDIP − JTube SNJ54BCT2244J SNJ54BCT2244J −55°C to 125°CCFP − W Tube SNJ54BCT2244W SNJ54BCT2244W LCCC − FKTubeSNJ54BCT2244FKSNJ54BCT2244FK†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at /sc/package.32120199101112134567818171615141Y12A41Y22A31Y31A22Y31A32Y21A4SN54BCT2244...FK PACKAGE(TOP VIEW)2Y 41A 11O E 1Y 42A 2O E2Y 1G N D 2A 1V C CCopyright © 2003, Texas Instruments IncorporatedPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.PRODUCTION DATA information is current as of pub lication date.SN54BCT2244, SN74BCT2244OCTAL BUFFERS AND LINE/MOS DRIVERS WITH 3-STATE OUTPUTSSCBS017D − SEPTEMBER 1988 − REVISED MARCH 2003FUNCTION TABLE (each buffer)INPUTS OUTPUTOE A YL H H L L L HXZlogic diagram (positive logic)1A11A21A31A41Y12A12A22A32A42Y11Y21Y31Y42Y22Y32Y41OE2OESN54BCT2244, SN74BCT2244OCTAL BUFFERS AND LINE/MOS DRIVERSWITH 3-STATE OUTPUTSSCBS017D − SEPTEMBER 1988 − REVISED MARCH 2003schematic of Y outputsOutputV CCGNDabsolute maximum ratings over operating free-air temperature range (unless otherwise noted)†Supply voltage range, V CC −0.5 V to 7 V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The IC operates based on IR's proprietary "One Cycle Control" (OCC) PFC algorithm based on the concept of resettable integrator.Theory of OperationThe OCC algorithm based on the resettable integrator concept works using two loops - a slow outer voltage loop and a fast inner current loop. The outer voltage loop monitors the VFB pin and generates an error signal which controls the amplitude of the input current admitted into the PFC converter. In this way, the outer voltage loop maintains output voltage regulation. The voltage loop bandwidth is kept low enough to not track the 2xf AC ripple in the output voltage and thus generates an almost DC error signal under steady state conditions.The inner current loop maintains the sinusoidal profile of the input current and thus is responsible for power factor correction. The information about the sinusoidal variation in input voltage is inherently available in the input line current (or boost inductor current). Thus there is no need to sense the input voltage to generate a current reference. The current loop employs the boost inductor current information to generate PWM signals with a proportional sinusoidal variation. This controls the shape of the input current to be proportional to and in phase with the input voltage. Average current mode operation is envisaged by filtering the switching frequency ripple from the current sense signal using an appropriately sized on-chip RC filter. This filter also contributes to the bandwidth of the current control loop. Thus the filter bandwidth has to be high enough to track the 120Hz rectified, sinusoidal current waveform and also filter out the switching frequency ripple in the inductor current. In IR1153 this averaging function can effectively filter high ripple current ratios (as high as 40% at maximum input current) to accommodate designs with small boost inductances.The IC determines the boost converter instantaneous duty cycle based on the resettable integrator concept. The required signals are the voltage feedback loop error signal V m (which is the V COMP pin voltage minus a DC offset of V COMP,START) and the current sense signal V ISNS. The resettable integrator generates a cycle-by-cycle, saw-tooth signal called the PWM Ramp which has an amplitude V m and period 1/f SW hence a slope of V m*f SW. The current sense signal is amplified by the current amplifier by a factor g DC and fed into the summing node where it is subtracted from V m to generate the summer voltage (= V m–g DC*V ISNS). The summer voltage is compared with the PWM ramp by the PWM comparator of the IC to determine the gate drive duty cycle. The instantaneous duty is mathematically given by:D = (V m - g DC.V ISNS)/V mAssuming steady state condition where the voltage feedback loop is well regulated (V m & V OUT are DC signals) & hence instantaneous duty cycle follows the boost-converter equation (D = 1 – V IN(t)/V OUT), the control equation can be re-written as:V m = g DC.V ISNS/(V IN(t)/V OUT)Further, recognizing that V ISNS = I L(t).R SNS and re-arranging yields:g DC.I L(t).R SNS = V m V IN(t)/V OUTSince V m, V OUT & g DC are constant terms:I L(t) α V IN(t)Thus the inductor current follows the input voltage waveform & by definition power factor correction is achieved.Feature setFixed Frequency OperationThe IC is programmed to operate at a fixed frequency of 22.2kHz (Typ). Internalization of the oscillator offers excellent noise immunity even in the noisy PFC environment while integration of the oscillator into the OCC core of the IC eliminates need for digital calibration circuits. Both these factors render the gate drive jitter free thus contributing to elimination of audible noise in PFC magnetics.IC Supply Circuit & Low start-up currentThe IR1153 UVLO circuit maintains the IC in UVLO mode during start-up if VCC pin voltage is less than the VCC turn-on threshold, V CC,ON and current consumption is less than 75uA. Should VCC pin voltage should drop below V CC,UVLO during normal operation, the IC is pushed back into UVLO mode and VCC pin has to exceed V CC,ON again for normal operation. There is no internal voltage clamping of the VCC pin.User initiated Micropower Sleep modeThe IC can be actively pushed into a micropower Sleep Mode where current consumption is less than 75uA by pulling OVP/EN pin below the Sleep threshold, V SLEEP even while VCC is above V CC,ON. This allows the user to disable PFC during application stand-by situations in order to meet stand-by regulations. Since V SLEEP is less than 1V, even logic level signals can be employed.IR1153SIR1153 General DescriptionProgrammable Soft StartThe soft start process controls the rate of rise of the voltage feedback loop error signal thus providing a linear increase of the RMS input current that the PFC converter will admit. The soft start time is essentially controlled by voltage error amplifier compensation components selected and is therefore user programmable to some degree based on desired voltage feedback loop crossover frequency.Gate Drive CapabilityThe gate drive output stage of the IC is a totem pole driver with 750mA peak current drive capability. The gate drive is internally clamped at 14.1V (Typ). Gate drive buffer circuits (especially cost-effective base-followers) can be easily driven with the GATE pin of the IC to suit any system power level.System Protection FeaturesIR1153 protection features include Brown-out protection (BOP), Open-loop protection (OLP), Overvoltage protection (OVP), Cycle-by-cycle peak current limit (IPK LIMIT), Soft-current limit and VCC under voltage lock-out (UVLO).- BOP is based on direct input line sensing using a resistor divider/RC filter network. If BOP pin falls below the Brown-out protection threshold V BOP, a Brown-out situation is immediately detected the following response is executed - the gate drive pulse is disabled, VCOMP is actively discharged and IC is pushed into Stand-by Mode. The IC re-enters normal operation only after BOP pin exceeds V BOP(EN). During start-up the IC is held in Stand-by Mode until this pin exceeds V BOP(EN).- OLP is activated whenever the VFB pin voltage falls below V OLP threshold. Once open loop is detected the following response is immediately executed - the gate drive is immediately disabled, VCOMP is actively discharged and the IC is pushed into Stand-by mode. There is no voltage hysteresis associated with this feature. During start-up the IC is held in Stand-by Mode until VFB exceeds V OLP. - The OVP pin is a dedicated pin for overvoltage protection that safeguards the system even if there is a break in the VFB feedback loop due to resistor divider failure etc. An overvoltage fault is triggered when OVP pin voltage exceeds the V OVP threshold of 106%VREF. The response of the IC is to immediately terminate the gate drive output and hold it in that state. The gate drive is re-enabled only after OVP pin voltage drops below V OVP(RST) threshold of 103% VREF. The exact voltage level at which overvoltage protection is triggered can be programmed by the user by carefully designing the OVP pin resistor divider. Itis recommended NOT to set the OVP voltage trigger limit less than 106% of DC bus voltage, since this can endanger the situation where the OVP reset limit will be less than the DC bus voltage regulation point – in this condition the voltage loop can become unstable.- Soft-current limit is an output voltage fold-back type protection feature encountered when the PFC converter input current exceeds to a point where the V m voltage saturates. As mentioned earlier, the amplitude of input current is directly proportional to V m, the error voltage of the feedback loop. V m is clamped to a certain maximum voltage inside the IC (given by V COMP,EFF parameter in datasheet). If the input current causes the V m voltage to saturate at its maximum value, then any further increase in input current will cause the duty cycle to droop which immediately forces the V OUT voltage of the PFC converter to fold-back. Since the highest current is at the peak of the AC sinusoid, the droop in duty cycle commences at the peak of the AC sinusoid when the soft-current limit is encountered. In most converters, the design of the current sense resistor is performed based on soft-current limit (i.e. V m saturation) and at the system condition which demands highest input current (minimum V AC & maximum P OUT).- Cycle-by-cycle peak current limit protection instantaneously turns-off the gate output whenever the ISNS pin voltage exceeds V ISNS(PK) threshold in magnitude. The gate drive is held in the low state as long as the overcurrent condition persists. The gate drive is re-enabled when the magnitude of ISNS pin voltage falls below the V ISNS(PK) threshold. This protection feature incorporates a leading edge blanking circuit to improve noise immunity.IR1153S IR1153 Pin DescriptionPin COM: This is ground potential pin of the IC. All internal devices are referenced to this point. Pin COMP: External circuitry from this pin to ground compensates the system voltage loop and programs the soft start time. The COMP pin is essentially the output of the voltage error amplifier. The voltage loop error signal V m used in the control algorithm is derived from V COMP (V m =V COMP–V COMP,START). V COMP is actively discharged using an internal resistance to below V COMP,START threshold whenever the IC is pushed into Stand-by mode (BOP or OLP condition) or UVLO/Sleep mode. The gate drive output and logic functions of the IC are inactive if VCOMP is less than V COMP,START. Also during start-up, the VCOMP voltage has to be less than V COMP,START in order to commence operation (i.e. a pre-bias on VCOMP will not allow IC to commence operation).Pin ISNS: ISNS pin is tied to the input of the current sense amplifier of the IC. The voltage at this pin, which provides the current sense information to the IC, has to be a negative voltage wrt the COM pin. Also since the IC is based on average current mode, the entire inductor current information is necessary. A current sense resistor, located below system ground along the return path to the bridge rectifier, is the preferred current sensing method. ISNS pin is also the inverting input to the cycle-by-cycle peak current limit comparator. Whenever V ISNS exceeds V ISNS(PK) threshold in magnitude, the gate drive is instantaneously disabled. Any external filtering of the ISNS pin must be performed carefully in order to ensure that the integrity of the current sense signal is maintained for cycle-by-cycle peak current limit protection.Pin BOP (Brown-out Protection): This pin is used to sense the rectified AC input line voltage through a resistor divider/capacitor network which is in effect a voltage division and averaging network, representing a scaled down signal of the average rectified input voltage (average DC voltage + 2xf AC ripple). During start-up the BOP pin voltage has to exceed V BOP(EN) in order to enable the IC to exit Stand-by mode and enter normal operation. A Brown-out situation is detected whenever the pin voltage falls below V BOP and the IC is pushed into Stand-by mode. Subsequently the pin has to exceed V BOP(EN) for the IC to exit Stand-by and resume normal operation.Pin OVP/EN: The OVP/EN pin is connected to the non-inverting input of the OVP(OVP) overvoltage comparator shown in the block diagram and thus is used to detect output overvoltage situations. The output voltage information is communicated to the OVP pin using a resistive divider. This pin also serves the second purpose of an ENABLE pin. The OVP/EN pin can be used to activate the IC into “micropower sleep” mode by pulling the voltage on this pin below the V SLEEP threshold.Pin VFB: The converter output voltage is sensed via a resistive divider and fed into this pin. VFB pin is the inverting input of the output voltage error amplifier. The non-inverting input of this amplifier is connected to an internal 5V reference. The impedance of the divider string must be low enough that it does not introduce substantial error due to the input bias currents of the amplifier, yet high enough to minimize power dissipation. Typical value of external divider total impedance will be around 2MΩ. VFB pin is also the inverting input to the Open Loop comparator. The IC is held in Stand-by Mode whenever VFB pin voltage is below V OLP threshold.Pin VCC: This is the supply voltage pin of the IC and sense node for the undervoltage lock out circuit. It is possible to turn off the IC by pulling this pin below the minimum turn off threshold voltage, V CC(UVLO) without damage to the IC. This pin is not internally clamped.Pin GATE: This is the gate drive output of the IC. It provides a drive current of ±0.75A peak with matched rise and fall times. The gate drive output of the IC is clamped at 14.1V(Typ).分销商库存信息:IRIR1153STRPBF IR1153SPBF。

Bypass them with a high quality ceramic capacitor to the GND pins.GND PINSThese pins return operational bias current to system ground. VO is measured with respect to GND. The GND pin sinks reference current established by the external resistor R T.VO PINSince this pin measures DCR voltage drop it is critical that it be Kelvin connected to the buck inductor output. Power accuracy may be degraded if the voltage at this pin is below VO min.VCS PINA switched current source internal to the IR3721 maintains the average voltage of this pin equal to the voltage of the VO pin. The average current into this pin is therefore proportional to buck inductor current. VRT PINA voltage reference internal to the IR3721 drives the V RT pin while the pin current is monitored and used to set the amplitude of the current monitor switched current source I REF. Connect this pin to GND through a precision resistor network R T. This network may include provision for canceling the positive temperature coefficient of the buck inductor’s DC resistance (DCR).VK PINThe voltage of the VK pin is used to modulate the amplitude of the DI pin. This is one of the terms used to determine the product of the multiplier output. If VK is connected to a fixed voltage then the output of the multiplier is proportional to current. If VK is connected to the buck converter output voltage then the output of the DI driven RC filter is proportional to power.DI PINThe Dl pin output has a duty ratio proportional to the current into VCS, and an amplitude equal to the voltage at the VK pin. The DI pin is intended to drive an external low pass filter. The output of this filter is the product of the current and voltage terms.FUNCTIONAL DESCRIPTIONPlease refer to the Functional Description Diagram below. Power flow from the buck converter inductor is the product of output voltage times the current I L flowing through the inductor.Power is measured with the aid of InternationalRectifier’s proprietary TruePower™ circuit. Current is converted to a duty ratio that appears at the DI pin. The duty ratio of the DI pin isΤ⋅)+(⋅=R T 2CS 1CS L RATIO DUTY V RR R DCR I DI Equation 1The full-scale current that can be measured corresponds to a duty ratio of one.The amplitude of the DI pin is the voltage appearing at pin VK. If a fixed voltage is applied to VK then the output of the RC filter driven by DI will be proportional to inductor current I L .If VO is applied to V K as shown in the figure then the output of the DI driven RC network will beproportional to power. The full-scale voltage that can be measured is established on the chip to be 1.8V.The full scale power P FS that can be measured is the product of full-scale voltage and full scale current.Figure 1 Functional Description DiagramTHERMAL COMPENSATION FOR INDUCTOR DCR CURRENT SENSINGThe positive temperature coefficient of the inductor DCR can be compensated if R T varies inversely proportional to the DCR. DCR of a copper coil, as a function of temperature, is approximated by)⋅)(+(⋅)(=)(Cu R R TCR T T T DCR T DCR -1Equation 2T R is some reference temperature, usually 25 °C, and TCR Cu is the resistive temperature coefficient ofcopper, usually assumed to be 0.39 %/°C near room temperature. Note that equation 2 is linearly increasing with temperature and has an offset of DCR(T R ) at the reference temperature.If R T incorporates a negative temperature coefficient thermistor then temperature effects of DCR can be minimized. Consider a circuit of two resistors and a thermistor as shown below.RpFigure 2 R T NetworkIf Rth is an NTC thermistor then the value of the network will decrease as temperature increases. Unfortunately, most thermistors exhibit far more variation with temperature than copper wire. One equation used to model thermistors is⎟⎟⎠⎞⎜⎜⎝⎛⎟⎟⎠⎞⎜⎜⎝⎛⋅)(=)(0110TT th th e T R T R - βEquation 3where R th (T) is the thermistor resistance at some temperature T, R th (T 0) is the thermistor resistance at the reference temperature T 0, and β is the material constant provided by the thermistor manufacturer. Kelvin degrees are used in the exponential term of equation 3. If R S is large and R P is small, thecurvature of the equivalent network resistance can be reduced from the curvature of the thermistor alone. Although the exponential equation 3 can nevercompensate linear equation 2 at all temperatures, a spreadsheet can be constructed to minimize error over the temperature interval of interest. Theequivalent resistance R T of the network shown as a function of temperature is)(++=)(T R R R T R th p s T 111Equation 4using R th (T) from equation 3.Equation 2 may be rewritten as a new function of temperature using equations 2 and 4 as follows:())(+⋅)(=)(ΤT DCR R R T R V T I 2CS 1CS T R FS Equation 5With Rs and Rp as additional free variables, use a spreadsheet to solve equation 5 for the desired full scale current while minimizing the I FS (T) variation over temperature.TYPICAL 2-PHASE DCR SENSING APPLICATIONThe IR3721 is capable of monitoring power in a multiphase converter. A Two Phase DCR Sensing Circuit is shown below. The voltage output of any phase is equal to that of any and every other phase because they are electrically connected and monitored at VO as before.Output current is the sum of the two inductor currents (I L1 + I L2). Superposition is used to derive the transfer function for multiphase sensing.

Because the voltage on the shunt resistor is directly proportional to the current I L through the inductor, R CS2 and C CS2 do not need to match the L / DCR time constant. Because the value of the shunt resistance does not change with temperature as the inductor DCR does, R T can be a fixed resistor.IFigure 4 Resistor Sensing CircuitCOMPONENT SELECTION GUIDELINES Use a 0.1 μF, 6.3V, X7R ceramic bypass capacitorfrom VDD to GND and from VK to GND.Filter the DI output with an RC filter to give a stable analog representation of the current or power. Some of the DI source resistance of this filter is internal to the IR3721 and specified in the electrical specifications table. Add twenty thousand to fifty thousand additional ohms externally to minimize resistance variation. As the DI source resistance increases beyond these guidelines, the voltage measurement error caused by non-ideal voltmeter conductance will increase.Select a filter capacitor that limits 512 kHz sampling frequency ripple to an acceptable value. Sampling frequency ripple will appear as an error, but can be reduced 20 dB for each decade that the filter corner frequency is below 512 kHz. Select a capacitor value that achieves the desired balance between low sampling frequency ripple and adequate bandwidth. Resistor current sensingFor resistor current sensing select a precision resistor for R T inside the R T resistance range limits specified in the Electrical Specifications table, such as 25.5kΩand 1% tolerance.Next, select a shunt resistor that will provide the most current sensing voltage while also considering the allowable power dissipation limitations. The DI output will saturate to the VK voltage when full scale current I FS flows through this shunt. Recommended maximum current sensing voltage range is 5 to 150 mV. Maximum sensing voltages less than 5 mV will cause comparator input offset voltage errors to dominate, and voltages larger than 150 mV will cause comparator leakage current, I CS, errors to dominate. Select R CS2 to be the next higher standard value resistor from (R SHUNT·I FS·R T) / V RT in order to accommodate full scale current I FS.Bypass VCS to VO with capacitor C CS2. The value of this capacitor limits the bandwidth, but is required because it is the integrator of the delta sigma modulator. Consider selecting the value of C CS2 to place a filter corner frequency at 5 kHz, which will reduce sampling ripple by 40 dB.DCR current sensingSelect an R T network resistance between 20kΩ and 45.3kΩ. Consider the R T network of Figure 5 for DCR current sensing.26.1 kΩ, 1%15.0 kΩ, 1%2.00 kΩ, 1%Murata ThermistorNCP15WB473F03RC47 kΩ, 1%Figure 5 R T networkThe resistance of the network above at 25°C, R T(25), is 37.58kΩ. Over temperature R T(T) is multiplied by copper resistance, DCR(25)·(1+(T-25)·0.0039), divided by (DCR(25)·( R T(25)) to normalize the results, and plotted as nominal error in Figure 6.Figure 6 Nominal error vs. TemperatureNote that the error due to temperature compensation at 25°C is zero, assuming ideal R T components. At other temperatures the results are over or under reported by the factor in percent indicated.Proceed to calculate R SUM, defined as the sum ofR CS1 plus R CS2, as follows.R SUM=I FS·DCR(25) ·R T(25) / V RTAgain, I FS is full scale current and V RT is the reference voltage establishing the current in R T.Estimate the capacitance C CS1 with the following equation.SUMCS R DCR LC ⋅)(⋅>2541Choose a standard capacitor value larger than indicated by the right hand side of the inequality above.Calculate the equivalent resistance R eq .R eq = L / (DCR(25) ·C CS1)We now have two equations, R SUM = R CS1 + R CS2 and Req = (R CS1 · R CS2) / (R CS1 + R CS2). Calculate R CS1 and R CS2 using the following two equations.⎟⎟⎟⎟⎟⎟⎠⎞⎜⎜⎜⎜⎜⎜⎝⎛⋅+⋅=2R R 411R R SUM eq SUM CS1- and⎟⎟⎟⎟⎟⎟⎠⎞⎜⎜⎜⎜⎜⎜⎝⎛⋅⋅=2R R 411R R SUM eq SUM 2CS --Use the next higher standard 1% value than indicated in the equations above. This will insure that full scale current can be measured.Bypass VCS to VO with capacitor C CS2. The value of this capacitor limits the bandwidth, but is required because it is the integrator of the delta sigmamodulator. Consider selecting the value of C CS2 to place a filter corner frequency at 5 kHz, which will reduce sampling ripple by 40 dB.分销商库存信息: IRIR3721MTRPBF。

The signals are arranged in functional groups according to their associated interface.The “n” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When “n” is not present before the signal name, the signal is asserted at the high voltage level.The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a signal is active, independent of whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inactive.5.1 Pin DescriptionsTable 5.2 USB2244/2244i 36-Pin QFN Pin DescriptionsNAMESYMBOL36-PIN QFNBUFFER TYPEDESCRIPTIONSECURE DIGITAL INTERFACESD DataSD_D[7:0]781020232545I/O12PUThe bi-directional signals should have weak pull-up resistors.
