ISO5852S 具有分离输出和有源安全特性的高 CMTI 2.5A5A 隔离式IGBT、 MOSFET 栅极驱动器

内置的去饱和 (DESAT) 故障检测功能可识别 IGBT 何时处于过流状态。中的文本由“IGBT 处于过载状态”更改为“IGBT 处于过流状态”。检测到 DESAT 时，“静音”逻辑会立即阻断隔离器输出，并启动软关断过程以禁止 OUTH 并将 OUTL 拉至低电平持续 2μs。中的文本由“并降低 OUTL 的电压持续 2μs 以上” 更改为“并将 OUTL 拉至低电平持续 2μs”。当 OUTL 达到 2V 时（相对于最大负电源电势 VEE2），栅极驱动器输出会被“硬”拉至 VEE2 电势，从而立即将 IGBT 关断。

方正君逸M580双网隔离(USB)计算机介绍

方正君逸M580双网隔离计算机背景随着互联网时代的到来，网络信息技术的高速发展已彻底颠覆了传统的办公模式，大大提高的工作效率使我们无法再离开网络；与此同时，我们也正受到日益严重的来自网络的安全威胁，诸如网络的数据窃贼、黑客的侵袭、病毒发布者，甚至系统内部的泄密者。

信息安全已经成为各行业信息化建设中的首要问题。

面对这一严峻形势，国家保密局、中保委相继出台信息安全要求，明确规定涉密计算机信息系统必须与国际互联网或其他公共信息网实行物理隔离。

应运而生——方正君逸M580双网隔离计算机“极速安全方正为先”，方正科技倾力打造国内领先通过公安部、保密局、军队三方认证的双网隔离PC整机--方正君逸M580双网隔离计算机。

这款双网隔离计算机是根据政府、金融、企业等对网络与信息安全有特殊要求的机关、单位的需求，采用最新的双网隔离技术研发而成，该产品具有“双网快速切换”、“实时在线”、“安全易用”和“高兼容性”等特色，能够达到“网内网外，安全畅享”的效果。

安全性设计目标方正君逸M580隔离网计算机，融入了完整的终端安全体系结构设计概念，实现了内外网络的绝对的物理隔离，同时做到了网络隔离、硬盘数据隔离、内存隔离。

通过物理隔离的方式，在二个网间实时在线地、自由地切换时，保证计算机的数据在网络之间不被重用。

根据本产品设计方法：当计算机进入其中一个网络时，内部物理隔离部件保证被隔离的计算机硬盘、内存及相应网络相互不连通。

在转换网络时，正在运行的操作系统挂起并释放所拥有的资源，由隔离部件保存重要的信息，并唤醒另一个睡眠中的系统，恢复它的相关信息。

这样，计算机的硬件资源使用了对操作系统而言完全独立的硬件资源，并且这些资源在数据信息相互独立（包括内存，显存, 硬盘等），从而在数据上没有任何的泄漏。

功能特点⏹与隔离卡产品相比，切换时间由原来的120-180秒缩短至5-8秒⏹快速切换的同时，始终保留用户的网络工作现场环境⏹人性化开机界面，鼠标/键盘均可选择进入内外网系统⏹内外网系统切换时，对存储介质（光、软、U）作安全检测，提示用户取出介质⏹网络连接自动检测，如果内、外网线插反，系统自动提示错误并切断连接，防止意外数据泄漏。

Basic Operation: CMOS Output (Active Low)1-1. When the power supply voltage (VDD) is higher than the release voltage (+VDET), the Nch transistor is OFF andthe Pch transistor is ON to provide VDD (high) at the output. Since the Nch transistor N1 in Figure 1 is OFF, thecomparator input voltage isC B A C B R R R VDD R R ++∙+)(.1-2. When the VDD goes below +VDET, the output provides the VDD level, as long as VDD remains above thedetection voltage (–VDET). When the VDD falls below –VDET (point A in Figure 2), the Nch transistor becomes ON, the Pch transistor becomes OFF, and the VSS level appears at the output. At this time the Nchtransistor N1 in Figure 1 becomes ON, the comparator input voltage is changed to B AB R R VDD R +∙.1-3. When the VDD falls below the minimum operating voltage, the output becomes undefined, or goes to VDD whenthe output is pulled up to VDD.1-4. The VSS level appears when VDD rises above the minimum operating voltage. The VSS level still appearseven when VDD surpasses the –VDET, as long as it does not exceed the release voltage +VDET.1-5. When VDD rises above +VDET (point B in Figure 2), the Nch transistor becomes OFF and the Pch transistorbecomes ON to provide VDD at the output. The VDD at the OUT pin is delayed for Td due to the delay circuit.2. Delay Circuit2-1. Delay TimeThe delay circuit delays the output signal from the time at which the power voltage (VDD) exceeds the release voltage (+VDET) when VDD is turned on. The output signal is not delayed when the VDD goes below the detection voltage (–VDET). (Refer to Figure 2.) The delay time (t D) is a fixed value that is determined by a built-in oscillation circuit and counter.2-2. DS Pin (ON/OFF Switch Pin for Delay Time)The DS pin should be connected to Low or High. When the DS pin is High, the output delay time becomes short since the output signal is taken from the middle of counter circuit (Refer to Figure 3).Directions for use：1、Please use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading orpermanent damage to the device.2、When a resistor is connected between the V DD pin and the input with CMOS output configurations, oscillation mayoccur as a result of voltage drops at R IN if load current(I OUT) exists.(refer to the Oscillation Description(1) below)3、When a resistor is connected between the V DD pin and the input with CMOS output configurations, oscillation mayoccur as a result of through current at the time of voltage release even if load current(I OUT) does not exist. (refer to the Oscillation Description(2) below)4、With a resistor connected between the V DD and the input, detect and release voltage will rise as a result of the IC’ssupply current flowing through the V DD pin.5、In order to stabilize the IC’s operations, please ensure that V DD pin’s input frequency’s rise and fall times are morethan several u Sec/V.Oscillation Description：1、 Output current oscillation with the CMOS output configurationWhen the voltage applied at IN rises, release operations commence and the detector’s output voltage increase.Load current(I OUT) will flow at R L. Because a voltage drop(R IN*I OUT) is produces at the R IN resistor, located between the input(IN) and the V DD pin. The load current will flow via the IC’s pin. The voltage drop will also lead toa fall in the voltage level at the V DD pin. When the V DD pin voltage level falls below the detect voltage level, detectoperations will commence. Fllowing detect operations, load current flow will cease and since voltage drop at R IN will disapper, the voltage level at the V DD pin will rise and release operations will begin over again. Oscillation may occur with this “release-detect-release” repetition. Further, this condition will also appear via means of a similar mechanism during detect operations.2、 Oscillation as a result of through currentSince the ME2805 series are CMOS IC’s, through current will flow when the IC’s internal circuit switching operates(during release and detect operations). Consequently, oscillation is liable to occur as a result of drops in voltage at the through current’s resistor(R IN) during release voltage operations.(refer to diagram 2) since hysteresis exists during detect operations, oscillation is unlikely to occur.Type Characteristics1、SUPPLY CURRENT VS.

A unique combina-tion of advanced circuit design and laser-wafer trimmed thin-film resistors provide the AD580 with an initial tolerance of ±0.4%, a temperature stability of better than 10 ppm/°C and long-term stability of better than 250 µV. In addition, the low quiescent current drain of 1.5 mA max offers a clear advantage over classical Zener techniques.The AD580 is recommended as a stable reference for all 8-, 10-and 12-bit D-to-A converters that require an external reference.In addition, the wide input range of the AD580 allows operation with 5 volt logic supplies making the AD580 ideal for digital panel meter applications or whenever only a single logic power supply is available.The AD580J, K, L and M are specified for operation over the 0°C to +70°C temperature range; the AD580S, T and U are specified for operation over the extended temperature range of –55°C to +125°C.*Protected by Patent Nos. 3,887,863; RE30,586.PRODUCT HIGHLIGHTSser-trimming of the thin-film resistors minimizes the AD580 output error. For example, the AD580L output tolerance is ±10 mV.2.The three-terminal voltage in/voltage out operation of the AD580 provides regulated output voltage without any external components.3.The AD580 provides a stable 2.5 V output voltage for input voltages between4.5 V and 30 V. The capability to provide a stable output voltage using a 5-volt input makes the AD580 an ideal choice for systems that con-tain a single logic power supply.4.Thin-film resistor technology and tightly controlled bipolar processing provide the AD580 with temperature stabilities to 10 ppm/°C and long-term stability better than 250 µV.5.The low quiescent current drain of the AD580 makes it ideal for CMOS and other low power applications.6.The AD580 is available in versions compliant with MIL-STD-883.

Consult the factory for specifications and applications information.THEORY OF OPERATIONThe AD580 family (AD580, AD581, AD584, AD589) uses the “bandgap” concept to produce a stable, low temperature coefficient voltage reference suitable for high accuracy data ac-quisition components and systems. The device makes use of the underlying physical nature of a silicon transistor base-emitter voltage in the forward-biased operating region. All such transis-tors have approximately a –2 mV/°C temperature coefficient,unsuitable for use directly as a low TC reference; however,extrapolation of the temperature characteristic of any one of these devices to absolute zero (with emitter current proportional to absolute temperature) reveals that it will go to a V BE of 1.205volts at 0K, as shown in Figure 1. Thus, if a voltage could be developed with an opposing temperature coefficient to sum with V BE to total 1.205 volts, a zero-TC reference would result and operation from a single, low voltage supply would be possible.The AD580 circuit provides such a compensating voltage, V 1 in Figure 2, by driving two transistors at different current densities and amplifying the resulting V BE difference (∆V BE —which now has a positive TC); the sum (V Z ) is then buffered and amplified up to 2.5 volts to provide a usable reference-voltage output. Fig-ure 3 is the schematic diagram of the AD580.The AD580 operates as a three-terminal reference, which means that no additional components are required for biasing or cur-rent setting. The connection diagram, Figure 4 is quite simple.Figure 1.Extrapolated Variation of Base-Emitter Voltage with Temperature (I E αT), and Required Compensation,Shown for Two Different DevicesFigure 2. Basic Bandgap-Reference Regulator CircuitAD580REV. A–4–Figure 3.AD580 Schematic DiagramFigure 4.AD580 Connection DiagramVOLTAGE VARIATION VS. TEMPERATURESome confusion exists in the area of defining and specifying reference voltage error over temperature. Historically, references are characterized using a maximum deviation per degree Centi-grade; i.e., 10 ppm/°C. However, because of the inconsistent nonlinearities in Zener references (butterfly or “S” type charac-teristics), most manufacturers use a maximum limit error band approach to characterize their references. This technique mea-sures the output voltage at 3 to 5 different temperatures and guarantees that the output voltage deviation will fall within the guaranteed error band at these discrete temperatures. This ap-proach, of course, makes no mention or guarantee of perfor-mance at any other temperature within the operating tempera-ture range of the device.The consistent Voltage vs. Temperature performance of a typi-cal AD580 is shown in Figure 5. Note that the characteristic is quasi-parabolic, not the possible “S” type characteristics of clas-sical Zener references. This parabolic characteristic permits a maximum output deviation specification over the device’s full operating temperature range, rather than just at 3 to 5 discretetemperatures.Figure 5.Typical AD580K Output Voltage vs. TemperatureThe AD580M guarantees a maximum deviation of 1.75 mV over the 0°C to +70°C temperature range. This can be shown to be equivalent to 10 ppm/°C average maximum; i.e.,1.75mV max 70°C ×12.5V =10ppm /°C max averageThe AD580 typically exhibits a variation of 1.5 mV over thepower supply range of 7 volts to 30 volts. Figure 6 is a plot of AD580 line rejection versus frequency.NOISE PERFORMANCEFigure 7 represents the peak-to-peak noise of the AD580 from 1 Hz (3 dB point) to a 3 dB high end shown on the horizontal axis. Peak-to-peak noise from 1 Hz to 1 MHz is approximately 600 µV.Figure 6.AD580 Line Rejection PlotFigure 7.Peak-to-Peak Output Noise vs. FrequencyAD580REV. A–5–Figure 8.Input Current vs. Input Voltage (Integral Loads)THE AD580 AS A CURRENT LIMITERThe AD580 represents an excellent alternative to current lim-iter diodes which require factory-selection to achieve a desired current. This approach often results in temperature coefficients of 1%/°C. The AD580 approach is not limited to a specially selected factory set current limit; it can be programmed from 1 mA to 10 mA with the insertion of a single external resistor.The approximate temperature coefficient of current limit for the AD580 used in this mode is 0.13%/°C for I LIM = 1 mA and 0.01%/°C for I LIM = 13 mA (see Figure 9). Figure 8 displays the high output impedance of the AD580 used as a current lim-iter for I LIM= 1, 2, 3, 4, 5 mA.Figure 9.A Two-Component Precision Current LimiterTHE AD580 AS A LOW POWER, LOW VOLTAGEPRECISION REFERENCE FOR DATA CONVERTERSThe AD580 has a number of features that make it ideally suited for use with A/D and D/A data converters used in complexmicroprocessor-based systems. The calibrated 2.500 volt output minimizes user trim requirements and allows operation from a single low voltage supply. Low power consumption (1 mAquiescent current) is commensurate with that of CMOS-type de-vices, while the low cost and small package complements the de-creasing cost and size of the latest converters.Figure 10 shows the AD580 used as a reference for the AD754212-bit CMOS DAC with complete microprocessor interface.The AD580 and the AD7542 are specified to operate from a single 5 volt supply; this eliminates the need to provide a +15volt power supply for the sole purpose of operating a reference.The AD7542 includes three 4-bit data registers, a 12-bit DAC register, and address decoding logic; it may thus be interfaced directly to a 4-, 8- or 16-bit data bus. Only 8 mA of quiescent current from the single +5 volt supply is required to operate the AD7542 which is packaged in a small 16-pin DIP. The AD544output amplifier is also low power, requiring only 2.5 mA quies-cent current. Its laser-trimmed offset voltage preserves the±1/2 LSB linearity of the AD7542KN without user trims and it typically settles to ±1/2 LSB in less than 3 µs. It will provide the 0 volt to –2.5 volt output swing from ±5 volt supplies.Figure 10. Low Power, Low Voltage Reference for the AD7542 Microprocessor-Compatible 12-Bit DACAD580REV.
