电源控制：
VCC1 可提供单电源控制也可以用来作为备用电源，VCC2 为主电源。在主电源关闭的情况下，也能保持时钟的 连续运行。DS1302 由 Vcc1 或 Vcc2 两者中的较大者供电。当 Vcc2 大于 Vcc1＋0.2V 时，Vcc2 给 DS1302 供电。当 Vcc2 小于 Vcc1 时，DS1302 由 Vcc1 供电。
数据输入：
经过 8 个时钟周期的控制字节的输入，一个字节的输入将在下 8 个时钟周期的上升沿完成，数据传输从字节最 低位开始。
数据输出：
经过 8 个时钟周期的控制读指令的输入，控制指令串行输入后，一个字节的数据将在下个 8 个时钟周期的下降 沿被输出，注意第一位输出是在最后一位控制指令所在脉冲的下降沿被输出，要求 RST 保持位高电平。
1. 可通过 Vcc1 进行涓流充电 2. 双重电源补给 3. 备用电源可采用电池或者超级电容(0.1F 以上)，可以用老式电脑主板上的 3.6V 充电电池。 如果断电时间较短(几小时或几天)时，就可以用漏电 较小的普通电解电容器代替。100 μ F 就可以保证 1 小时的正常走时。DS1302 在第一次加电后，必须进行 初始化操作。初始化后就可以按Hale Waihona Puke 常方法调整时间。1 / 10

Burst mode operation and device very low consumption helps to meet the standby energy saving regulations.Advance frequency jittering reduces EMI filter cost. Brown-out function protects the switch mode power supply when the rectified input voltage level is below the normal minimum level specified for the system. The high voltage start-up circuit is embedded in the device.VIPER17Table 1.Device summaryOrder codesPackage Packaging VIPER17LN / VIPER17HN DIP-7Tube VIPER17HD / VIPER17LD SO16 narrowTube VIPER17HDTR / VIPER17LDTRT ape and reelContents VIPER17Contents1Block diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 2Typical power . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 43Pin settings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 53.1Connection diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 53.2Pin description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 54Electrical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 64.1Maximum ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 64.2Thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 64.3Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 5Typical electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 6Typical circuit . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 147Operation descriptions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 157.1Power section and gate driver . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 157.2High voltage startup generator . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 157.3Power-up and soft-start up . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 167.4Power down operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 187.5Auto restart operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 187.6Oscillator . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 187.7Current mode conversion with adjustable current limit set point . . . . . . . 197.8Over voltage protection (OVP) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 197.9About CONT pin . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 217.10Feed-back and over load protection (OLP) . . . . . . . . . . . . . . . . . . . . . . . 217.11Burst-mode operation at no load or very light load . . . . . . . . . . . . . . . . . . 247.12Brown-out protection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 257.132nd level over current protection and hiccup mode . . . . . . . . . . . . . . . . . 27 2/33VIPER17Contents 8Package mechanical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28 9Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 323/33Block diagram VIPER174/331 Block diagram2 Typical powerTable 2.Typical powerPart number 230 V AC85-265 V ACAdapter (1)Open frame (2)Adapter (1)Open frame (2)VIPER179 W12 W5 W7 W1.Typical continuous power in non ventilated enclosed adapter measured at 50 °C ambient.2.Maximum practical continuous power in an open frame design at 50 °C ambient, with adequate heat sinking.VIPER17Pin settings5/333 Pin settings3.1 Connection diagram3.2 Pin descriptionTable 3.Pin descriptionPin N.NameFunctionDIP-7SO161 1...4GND This pin represents the device ground and the source of the power section. 25VDDSupply voltage of the control section. This pin also provides the charging currentof the external capacitor during start-up time.36CONTControl pin. The following functions can be selected:1. current limit set point adjustment. The internal set default value of the cycle-by-cycle current limit can be reduced by connecting to ground an external resistor.2. output voltage monitoring. A voltage exceeding 3 V shuts the IC downreducing the device consumption. This function is strobed and digitally filtered for high noise immunity.47FBControl input for duty cycle control. Internal current generator provides bias current for loop regulation. A voltage below 0.5 V activates the burst-mode operation. A level close to 3.3 V means that we are approaching the cycle-by-cycle over-current set point.510BRBrownout protection input with hysteresis. A voltage below 0.45 V shuts down (not latch) the device and lowers the power consumption. Device operation restarts as the voltage exceeds 0.45 V plus hysteresis voltage.

The burst mode operation guaranties high performance in the stand-by mode and helps in the energy saving norm accomplishment.All the fault protections are built in auto restart mode with very low repetition rate to prevent IC's over heating.7.1 Power section and gate driverThe power section is implemented with an avalanche ruggedness N-channel MOSFET, which guarantees safe operation within the specified energy rating as well as high dv/dt capability. The Power section has a BV DSS of 800 V min. and a typical R DS(on) of 20 Ω at 25 °C.The integrated SenseFET structure allows a virtually loss-less current sensing.The gate driver is designed to supply a controlled gate current during both turn-on and turn-off in order to minimize common mode EMI. Under UVLO conditions an internal pull-down circuit holds the gate low in order to ensure that the Power section cannot be turned on accidentally.7.2 High voltage startup generatorThe HV current generator is supplied through the DRAIN pin and it is enabled only if the input bulk capacitor voltage is higher than V DRAIN_ST ART threshold, 80 V DC typically. When the HV current generator is ON, the IDD_ch current (3 mA typical value) is delivered to the capacitor on the V DD pin. In case of Auto Restart mode after a fault event, the IDD_chcurrent is reduced to 0.6 mA, typ. in order to have a slow duty cycle during the restart phase.Operation descriptions VIPER1716/337.3 Power-up and soft-start upIf the input voltage rises up till the device start level (V DRAIN_ST ART ), the V DD voltage begins to grow due to the IDD_ch current (see Table 7 on page 7) coming from the internal high voltage start up circuit. If the V DD voltage reaches V DDon threshold (~14 V) the power MOSFET starts switching and the HV current generator is turned OFF . See Figure 23 on page 17.The IC is powered by the energy stored in the capacitor on the VDD pin, C VDD , until when the self-supply circuit (typically an auxiliary winding of the transformer and a steering diode) develops a voltage high enough to sustain the operation.C VDD capacitor must be sized enough to avoid fast discharge and keep the needed voltage value higher than V DDoff threshold. In fact, a too low capacitance value could terminate the switching operation before the controller receives any energy from the auxiliary winding. The following formula can be used for the V DD capacitor calculation:Equation 1The t SSaux is the time needed for the steady state of the auxiliary voltage. This time is estimated by applicator according to the output stage configurations (transformer, output capacitances, etc.).During the converter start up time, the drain current limitation is progressively increased to the maximum value. In this way the stress on the secondary diode is considerably reduced. It also helps to prevent transformer saturation. The soft-start time lasts 8.5 ms and the feature is implemented for every attempt of start up converter or after a fault.C VDD I DDch t SSaux ×V DDon V DDoff–----------------------------------------=VIPER17Operation descriptions17/33Operation descriptions VIPER177.4 Power down operationAt converter power down, the system loses regulation as soon as the input voltage is so lowthat the peak current limitation is reached. The V DD voltage drops and when it falls belowthe V DDoff threshold (8 V typical) the power MOSFET is switched OFF, the energy transfersto the IC interrupted and consequently the V DD voltages decreases, Figure23 on page17.Later, if the V IN is lower than V DRAIN_START (80 V typical), the start up sequence is inhibitedand the power down completed. This feature is useful to prevent converter’s restart attemptsand ensures monotonic output voltage decay during the system power down.7.5 Auto restart operationIf after a converter power down, the V IN is higher than V DRAIN_ST ART, the start up sequenceis not inhibited and will be activated only when the V DD voltage drops down the V DDrestartthreshold (4.5 V typical). This means that the HV start up current generator restarts the V DDcapacitor charging only when the V DD voltage drops below V DDrestart. The scenario abovedescribed is for instance a power down because of a fault condition. After a fault condition,the charging current is 0.6 mA (typ.) instead of the 3 mA (typ.) of a normal start up converterphase. This feature together with the low V DDrestart threshold (4.5 V) ensures that, after afault, the restart attempts of the IC has a very long repetition rate and the converter workssafely with extremely low power throughput. The Figure25 shows the IC behavioral after ashort circuit event.7.6 OscillatorThe switching frequency is internally fixed to 60 kHz or 115 kHz. In both case the switchingfrequency is modulated by approximately ±4 kHz (60 kHz version) or ±8 kHz(115 kHz version) at 250 Hz (typical) rate, so that the resulting spread-spectrum actiondistributes the energy of each harmonic of the switching frequency over a number of side-band harmonics having the same energy on the whole but smaller amplitudes.18/33VIPER17Operation descriptions19/337.7Current mode conversion with adjustable current limit set pointThe device is a current mode converter: the drain current is sensed and converted in voltage that is applied to the non inverting pin of the PWM comparator. This voltage is compared with the one on the feed-back pin through a voltage divider on cycle by cycle basis.The VIPER17 has a default current limit value, I DLIM , that the designer can adjust according the electrical specification, by the R LIM resistor connected to the CONT see Figure 16 on page 12.The CONT pin has a minimum current sunk needed to activate the I DLIM adjustment: without R LIM or with high R LIM (i.e. 100 K Ω) the current limit is fixed to the default value (see I DLIM , Table 8 on page 8).7.8 Over voltage protection (OVP)The device can monitor the converter output voltage. This operation is done by CONT pin during power MOSFET OFF-time, when the voltage generated by the auxiliary winding tracks converter's output voltage, through turn ratio See Figure 26.In order to perform the output voltage monitor, the CONT pin has to be connected to the aux winding through a resistor divider made up by R LIM and R OVP (see Figure 21 and Figure 27). If the voltage applied to the CONT pin exceeds the internal 3 V reference for fourconsecutive times the controller recognizes an over voltage condition. This special feature uses an internal counter; that is to reduce sensitivity to noise and prevent the latch from being erroneously activated. see Figure 26 on page 20. The counter is reset every time the OVP signal is not triggered in one oscillator cycle.Referring to the Figure 21, the resistors divider ratio k OVP will be given by:Equation 2Equation 3N AUXN SEC--------------k OVP V OVPN AUXN SEC--------------V OUTOVP V DSEC +()V DAUX –⋅--------------------------------------------------------------------------------------------------=k OVP R LIMR LIM R OVP+---------------------------------=Operation descriptions VIPER1720/33Where:●V OVP is the OVP threshold (see Table8 on page9)●V OUT OVP is the converter output voltage value to activate the OVP (set by designer)designer●N AUX is the auxiliary winding turns●N SEC is the secondary winding turns●V DSEC is the secondary diode forward voltage●V DAUX is the auxiliary diode forward voltage●R OVP together R LIM make the output voltage dividerThan, fixed R LIM, according to the desired I DLIM, the R OVP can be calculating by: Equation 4The resistor values will be such that the current sourced and sunk by the CONT pin be within the rated capability of the internal clamp.R OVP R LIM1k OVP–k OVP----------------------×=VIPER17Operation descriptions21/337.9 About CONT pinReferring to the Figure 27, through the CONT PIN, the below features can be implemented:1.Current Limit set point2.Over voltage protection on the converter output voltageThe Table 9on page 21 referring to the Figure 27, lists the external resistance combinations needed to activate one or plus of the CONT pin functions.7.10 Feed-back and over load protection (OLP)The VIPER17 is a current mode converter: the feedback pin controls the PWM operation, controls the burst mode and actives the overload protection of the device. Figure 28 on page 23 and Figure 29 show the internal current mode structure.With the feedback pin voltage between V FBbm and V FBlin , (respectively 0.5 V and 3.3 V ,typical values) the drain current is sensed and converted in voltage that is applied to the non inverting pin of the PWM comparator.This voltage is compared with the one on the feedback pin through a voltage divider on cycle by cycle basis. When these two voltages are equal, the PWM logic orders the switch off of the power MOSFET . The drain current is always limited to I DLIM value.In case of overload the feedback pin increases in reaction to this event and when it goes higher than V FBlin the drain current is limited or to the default I DLIM value or the one imposedTable 9.CONT pin configurationsFunction / componentR LIM (1)1.R LIM have to be fixed before R FF and R OVPR OVP D AUX I Dlim reductionSee Figure 8No No OVP≥ 80 K ΩSee Equation 4Y es I Dlim reduction + OVPSee Figure 8See Equation 4Y esOperation descriptions VIPER1722/33through a resistor at the CONT pin (using the R LIM, see Figure16 on page12); the PWM comparator is disabled.At the same time an internal current generator starts to charge the feedback capacitor (C FB) and when the feedback voltage reaches the V FBolp threshold, the converter is turned off and the start up phase is activated with reduced value of I charge to 0.6 mA.During the first start up phase of the converter, after the soft-start up time (typical value is 8.5 ms) the output voltage could force the feedback pin voltage to rise up to the V FBolp threshold that switches off the converter itself.To avoid this event, the appropriate feedback network has to be selected according to the output load. More the network feedback fixes the compensation loop stability. The Figure28 on page23 and Figure29 show the two different feedback networks.The time from the over load detection (VFB = V FBlin) to the device shutdown(VFB = V FBolp) can be calculating by C FB value (see Figure28 on page23 and Figure29), using the formula:Equation 5In the Figure28, the capacitor connected to FB pin (C FB) is used as part of the circuit to compensate the feedback loop but also as element to delay the OLP shut down owing to the time needed to charge the capacitor (see equation 5).After the start up time, 8.5 ms typ value, during which the feedback voltage is fixed at V FBlin, the output capacitor could not be at its nominal value and the controller interpreter this situation as an over load condition. In this case, the OLP delay helps to avoid an incorrect device shut down during the start up.Owing to the above considerations, the OLP delay time must be long enough to by-pass the initial output voltage transient and check the over load condition only when the output voltage is in steady state. The output transient time depends from the value of the output capacitor and from the load.When the value of the C FB capacitor calculated for the loop stability is too low and cannot ensure enough OLP delay, an alternative compensation network can be used and it is showed in Figure29 on page23.Using this alternative compensation network, two poles (f PFB, f PFB1) and one zero (f ZFB) are introduced by the capacitors C FB and C FB1 and the resistor R FB1.The capacitor C FB introduces a pole (f PFB) at higher frequency than f ZB and f PFB1. This pole is usually used to compensate the high frequency zero due to the ESR (Equivalent Series Resistor) of the output capacitance of the fly-back converter.The mathematical expressions of these poles and zero frequency, considering the scheme in Figure29 are reported by the equations below:Equation 6T OLP delay–C FBV FBolp V FBlin–3μA---------------------------------------×=VIPER17Operation descriptions Equation 7Equation 8The R FB(DYN) is the dynamic resistance seen by the FB pin.The C FB1 capacitor fixes the OLP delay and usually C FB1 results much higher than C FB.The Equation 5 can be still used to calculate the OLP delay time but C FB1 has to beconsidered instead of C FB. Using the alternative compensation network, the designer cansatisfy, in all case, the loop stability and the enough OLP delay time alike.23/33Operation descriptions VIPER177.11 Burst-mode operation at no load or very light loadWhen the voltage on feedback pin falls down 50 mV below the burst mode threshold, V FBbm,power MOSFET is not more allowed to be switched on. It can be switched on again if thevoltage on feedback pin exceeds V FBbm. The voltage on PWM comparator non invertinginternal input, connected to feedback pin through a resistive voltage divider, is lowerclamped to a certain value leading to a minimum value, of 90 mA (typ.) for the drain peakcurrent.When the load decrease the feedback loop reacts lowering the feedback pin voltage. As thevoltage goes 50 mV below V FBbm MOSFET stops switching. After the MOSFET stops, as aresult of the feedback reaction to the energy delivery stop, the feedback pin voltageincreases and exceeding V FBbm threshold MOSFET the power device start switching again.Figure30 shows this behavior called burst mode. Systems alternates period of time wherepower MOSFET is switching to period of time where power MOSFET is not switching. Thepower delivered to output during switching periods exceeds the load power demands; theexcess of power is balanced from not switching period where no power is processed. Theadvantage of burst mode operation is an average switching frequency much lower then thenormal operation working frequency, up to some hundred of hertz, minimizing all frequencyrelated losses.24/33VIPER17Operation descriptions25/337.12 Brown-out protectionBrown-out protection is a not-latched shutdown function activated when a condition of mainsunder voltage is detected.The Brown-out comparator is internally referenced to V BRth ,0.45 V typ value, and disables the PWM if the voltage applied at the BR pin is below this internal reference. Under this condition the power MOSFET is turned off. Until the Brown out condition is present, the VDD voltage continuously oscillates between the V DDon and the UVLO thresholds, as shown in the timing diagram of Figure 31 on page 25. A voltage hysteresis is present to improve the noise immunity.The switching operation is restarted as the voltage on the pin is above the reference plus the before said voltage hysteresis. See Figure 31.The Brown-out comparator is provided also with a current hysteresis, I BRhyst .With thisapproach is possible to set the V INon threshold and V INoff thresholds separately, by properly choosing the resistors of the divider connect to the BR pin.Fixed the V INon and the V INoff levels, with reference to Figure 31, the following relationships can be established for the calculation of the resistors R H and R L :Equation 9。

DS91D176/DS91C176Multipoint-LVDS (M-LVDS)TransceiversGeneral DescriptionThe DS91C176and DS91D176are high-speed M-LVDS differential transceivers designed for multipoint applications with multiple drivers or receivers.Multipoint LVDS (M-LVDS)is a new bus interface standard (TIA/EIA-899)based on LVDS but including several enhancements to improve multi-point performance.M-LVDS devices have superior drive capability and can support up to 32loads.Along with in-creased drive,M-LVDS devices are required to have a con-trolled edge rate to minimize reflections and EMI.The 1nSec minimum edge rate is tolerant of stub lengths up to 2inches in length.M-LVDS devices also have a very large common mode range for additional noise margin in heavily loaded and noisy backplane environments.The DS91C176/DS91D176are half-duplex transceivers that accept LVTTL/LVCMOS signals at the driver inputs and con-vert them to differential M-LVDS signal levels.The receiver inputs accept low voltage differential signals (LVDS,B-LVDS,M-LVDS,LV-PECL)and convert them to 3V LVC-MOS signals.The DS91C176receiver contains an M-LVDS type 2failsafe circuit with an internal 100mV offset that provides a LOW output for both short and open input condi-tions.Featuresn Meets TIA/EIA-899M-LVDS Standard n Capable of driving 32LVDS loadsn Controlled Edge Rates Tolerant to Stubsn Wide Common Mode for Increased

trace is greater than 1/5of the transition edge,then the trace is considered a transmission line.If the velocity equals 160ps per inch fora typical loaded backplane,then the maximum stub length is 312ps/160ps/inch or 1.95inches (approximately 2inches).To determine the maximum stub for your backplane,the propagation velocity for the backplane is required (refer to application notes AN-905and AN-808).Typical Performance CharacteristicsSupply Current vs.FrequencyOutput VOD vs.Load Resistance20024662Supply Current measured using a clock pattern with driver terminated to 50ohms .V CC =3.3V,T
