Zero/span capabilities are also optionally available via these buttons with or withoutselection of a display option.Handheld ConfigurationSmartLine transmitters feature two-way communication and configuration capability between the operator and the transmitter. All Honeywell transmitters are designed andtested for compliance with the offered communication protocols and are designed to operate with any standards compliant handheld configuration device, such as the Honeywell Versatilis Configurator.Personal Computer ConfigurationOn a personal computer or laptop, Honeywell Field Device Manager (FDM) Software and FDM Express can be used for managing HART & Fieldbus device configurations.System Integration•SmartLine communications protocols all meet the most current published standards for HART/DE/Fieldbus.•Integration with Honeywell’s Experion PKS offers the following unique advantages.o Transmitter messaging.o Maintenance mode indication.o Tamper reporting.o FDM Plant Area Views with Health summaries.o All ST 800 units are Experion tested to providethe highest level of compatibility assurance.STA800 Smart Pressure Transmitter 3Modular DesignTo help contain maintenance & inventory costs, all ST 800 transmitters are modular in design supporting the user’s ability to replace meter bodies, add indicators or change electronic modules without affecting overall performance or approval body certifications. Each meter body is uniquely characterized to provide in-tolerance performance over a wide range of application variations in temperature and pressure and due to the Honeywell advanced interface, electronic modules may be swapped with any electronics module without losing in-tolerance performance characteristics.Modular Features•Meter body replacement•Exchange/replace electronics/comms modules*•Add or remove integral indicators*•Add or remove lightning protection (terminalconnection)** Field replaceable in all electrical environments (including IS) except flameproof without violating agency approvals.With no performance effects, Honeywell’s unique modularity results in lower inventory needs and lower overall operating costs. Plugged Impulse Line DetectionSTA800 models are offered with a PILD option which provides indication of a plugged impulse line or process connection. When used in conjunction with an advanced display, a non-critical diagnostic indication appears on the integral display. For units without an integral display, an indication can be seen via the host or handheld device when HART Protocol is utilized.Dual/Triple CalibrationSTA800 models are optionally offered with multiple calibrations. In lieu of a standard factory calibration, units can be supplied with 1, 2, or 3 customer specified calibrations. These calibrations are stored in the meter body and provide users with factory calibrated performance at up to three different calibrated ranges. This increases application flexibility without requiring any costly recalibration or additional inventory.4 STA800 Smart Pressure Transmitter Performance SpecificationsReference Accuracy:(conformance to +/-3 Sigma)Performance SpecificationsAccuracy at Specified Span and Temperature: (Combined Zero & Span, conformance to +/-3 Sigma)STA800 Smart Pressure Transmitter 5 Total Performance (% of Span):Total Performance Calculation: = +/- √(Accuracy)2 + (Temperature Effect)2Total Performance Examples (for comparison): standard accuracy 5:1 Turndown, +/-50o F (28o C) shiftTypical Calibration Frequency:Calibration verification is recommended every four (4) years.Notes:1.

NOTE: For detailed information on purchasing options, contact your local Allegro field applications engineer or sales representative.Allegro MicroSystems, Inc. reserves the right to make, from time to time, revisions to the anticipated product life cycle plan for a product to accommodate changes in production capabilities, alternative product availabilities, or market demand. The information included herein is believed to be accurate and reliable. However, Allegro MicroSystems, Inc. assumes no respon-sibility for its use; nor for any infringements of patents or other rights of third parties which may result from its use.Recommended Substitutions:For existing customer transition, and for new customers or new appli-cations, refer to the ACS712.Bidirectional 1.5 mΩ Hall Effect Based Linear Current Sensor ICwith V oltage Isolation and 15 A Dynamic RangeACS706ELC-05CDate of status change: December 26, 2006These parts are in production but have been determined to beNOT FOR NEW DESIGN. This classification indicates that sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is probable. Samples are no longer available.Not for New DesignFeatures and Benefits• Small footprint, low-profile SOIC8 package• 1.5 m Ω internal conductor resistance• 1600 V RMS minimum isolation voltage between pins 1-4 and 5-8• 4.5 to 5.5 V, single supply operation • 50 kHz bandwidth• 133 mV/A output sensitivity and 15 A dynamic range • Output voltage proportional to ac and dc currents • Factory-trimmed for accuracy• Extremely stable output offset voltage • Near-zero magnetic hysteresis• Ratiometric output from supply voltageThe Allegro ACS706 family of current sensor ICs provides economical and precise solutions for current sensing in industrial, automotive, commercial, and communications systems. The device package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, switch-mode power supplies, and overcurrent fault protection.The device consists of a precision, low-offset linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy at the factory.The output of the device has a positive slope (>V CC / 2) when an increasing current flows through the primary copper conduction path (from pins 1 and 2, to pins 3 and 4), which is the path used for current sampling. The internal resistance of this conductive path is typically 1.5 m Ω, providing low power loss. The thickness of the copper conductor allows survival of the device at up to 5× overcurrent conditions. The terminals of the conductive path are electrically isolated from the signal leads (pins 5 through 8). This allows the ACS706 to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques.The ACS706 is provided in a small, surface mount SOIC8 package. The leadframe is plated with 100% matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes. Internally, the flip-chip uses high-temperature Pb-based solder balls, currently exempt from RoHS. The device is fully calibrated prior to shipment from the factory.Use the following complete part number when ordering:Part NumberPackageACS706ELC-05CSOIC8 surface mountTÜV AmericaCertificate Number:U8V 04 12 54214 005AB S O L UTE MAX I M UM RAT I NGSSupply V oltage, V CC ..........................................16 V Reverse Supply V oltage, V RCC ........................–16 V Output V oltage, V OUT ........................................16 V Reverse Output V oltage, V ROUT ......................–0.1 V Output Current Source, I OUT(Source) ................. 3 mA Output Current Sink, I OUT(Sink) .......................10 mA Maximum Transient Sensed Current *, I R(max) ...100 A Operating Temperature, Maximum Junction, T J(max).......................165°C Storage Temperature, T S ......................–65 to 170°C*Junction Temperature, T J < TJ(max).*100 total pulses, 250 ms duration each, applied at a rate of1 pulse every 100 seconds.Nominal Operating Temperature, T A Range E ............................................–40 to 85ºC Overcurrent Transient Tolerance*, I P ................60 ABidirectional 1.5 m Ω Hall Effect Based Linear Current Sensorwith Voltage Isolation and 15 A Dynamic RangePackage LCPin 1: IP+Pin 2: IP+Pin 3: IP–Pin 4: IP–Pin 8: VCC Pin 7: VOUTPin 6: N.C.Pin 5: GNDPins 6 and 7 are internally connected in shipping product.

R F and C F, are recommended for noise management,with values that depend on the application, as shown in the noise filtering table.Sensitivity (Sens). The change in device output in response to a 1 A change through the primary conductor. The sensitivity is the prod-uct of the magnetic circuit sensitivity (G / A ) and the linear IC amplifier gain (mV/G). The linear IC amplifier gain is programmed at the factory to optimize the sensitivity (mV/A) for the full-scale current of the device.Noise (V NOISE ). The product of the linear IC amplifier gain (mV/G) and the noise floor for the Allegro Hall effect linear IC (≈1 G). The noise floor is derived from the thermal and shot noise observed in Hall elements. Dividing the noise (mV) by the sensitivity (mV/A) provides the smallest current that the device is able to resolve.Linearity (E LIN ): The degree to which the voltage output from the device varies in direct proportion to the primary current through its full-scale amplitude. Nonlinearity in the output can be attributed to the saturation of the flux concentrator approaching the full-scale current. The following equation is used to derive the linearity:Definitions of Accuracy Characteristics1001– [{[{V out_full-scale amperes –V OUT(Q)()2 (V out_half-scale amperes –V OUT(Q))100where V out_full-scale amperes = the output voltage (V) when the sensed current approximates full-scale ±I P .Symmetry (E SYM ). The degree to which the absolute voltage output from the device varies in proportion to either a positive or nega-tive full-scale primary current. The following formula is used to derive symmetry:Quiescent output voltage (V OUT(Q)). The output of the device when the primary current is zero. For a unipolar supply voltage, it nominally remains at V CC ⁄ 2. Thus, V CC = 5 V translates into V OUT(Q) = 2.5 V . Variation in V OUT(Q) can be attributed to the resolution of the Allegro linear IC quiescent voltage trim and thermal drift.Electrical offset voltage (V OE ). The deviation of the device output from its ideal quiescent value of V CC / 2 due to nonmagnetic causes. To convert this voltage to amperes, divide by the device sensitivity, Sens.Accuracy (E TOT ). The accuracy represents the maximum deviation of the actual output from its ideal value. This is also known as the total ouput error. The accuracy is illustrated graphically in the Output V oltage versus Current chart on the following page.Accuracy is divided into four areas:∙ 0 A at 25°C. Accuracy at zero current flow at 25°C, without the effects of temperature.∙ 0 A over Δ temperature. Accuracy at zero current flow including temperature effects.∙ Full-scale current at 25°C. Accuracy at the full-scale current at 25°C, without the effects of temperature.∙ Full-scale current over Δ temperature. Accuracy at full-scale current flow including temperature effects.Ratiometry . The ratiometric feature means that its 0 A output, V OUT(Q), (nominally equal to V CC /2) and sensitivity, Sens, are propor-tional to its supply voltage, V CC . The following formula is used to derive the ratiometric change in 0 A output voltage, ∆V OUT(Q)RAT (%):100V IOUT(Q)VCC /V IOUT(Q)5VV CC /5 VThe ratiometric change in sensitivity, ∆Sens RAT (%), is defined as:100Sens VCC /Sens 5V V CC /5 V ‰Output voltage vs. current, illustrating device accuracy at 0 A and at full-scale currentDefinitions of Dynamic Response CharacteristicsPropagation delay (t PROP): The time required for the device output to reflect a change in the primary cur-rent signal. Propagation delay is attributed to inductive loading within the linear IC package, as well as in the inductive loop formed by the primary conductor geometry. Propagation delay can be considered as a fixed time offset and may be compensated.Response time (t RESPONSE): The time interval between a) when the primary current signal reaches 90% of its final value, and b) when the device reaches 90% of its output corresponding to the applied current.Rise time (t r): The time interval between a) when the device reaches 10% of its full scale value, and b) when it reaches 90% of its full scale value. The rise time to a step response is used to derive the bandwidth of the device, in which ƒ(–3 dB) = 0.35 / t r. Both t r and t RESPONSE are detrimentally affected by eddy current losses observed in the conductive IC ground plane.Device Branding Key (Two alternative styles are used)ACS706T ELC05C YYWWA ACS Allegro Current Sensor706Device family numberT Indicator of 100% matte tin leadframe platingE Operating ambient temperature range codeLC Package type designator05C Primary sensed currentYY Manufacturing date code: Calendar year (last two digits) WW Manufacturing date code: Calendar weekA Manufacturing date code: Shift codeACS706T ELC05CL...L YYWWACS Allegro Current Sensor706Device family numberT Indicator of 100% matte tin leadframe platingE Operating ambient temperature range codeLC Package type designator05C Primary sensed currentL...L Manufacturing lot codeYY Manufacturing date code: Calendar year (last two digits)WW Manufacturing date code: Calendar week Standards and Physical SpecificationsParameter SpecificationFlammability (package molding compound)UL recognized to UL 94V-0Fire and Electric Shock UL60950-1:2003EN60950-1:2001CAN/CSA C22.2 No. 60950-1:2003Chopper Stabilization TechniqueChopper Stabilization is an innovative circuit technique that is used to minimize the offset voltage of a Hall element and an associated on-chip amplifier. Allegro patented a Chopper Stabilization technique that nearly eliminates Hall IC output drift induced by temperature or package stress effects. This offset reduction technique is based on a signal modulation-demodulation process. Modulation is used to separate the undesired dc offset signal from the magnetically induced signal in the frequency domain. Then, using a low-pass filter, the modu-lated dc offset is suppressed while the magnetically induced signal passes through the filter. As a result of this chopper stabilization approach, the output voltage from the Hall IC is desensitized to the effects of temperature and mechanical stress. This technique produces devices that have an extremely stable Electrical Offset V oltage, are immune to thermal stress, and have precise recoverability after temperature cycling.This technique is made possible through the use of a BiCMOS process that allows the use of low-offset and low-noise amplifiers in combination with high-density logic integration and sample and hold circuits.Concept of Chopper Stabilization TechniqueApplications InformationIn order to quantify transient common-mode voltage rejection for the ACS706, a device was soldered onto a printedcircuit board. A 0.1 μF bypass capacitor and a 5 V dc power supply were connected between VCC and GND (pins 8 and5) for this device. A 10 k Ω load resistor and a 0.01 μF capacitor were connected in parallel between the VOUT pin andthe GND pin of the device (pins 7 and 5).A function generator was connected between the primary current conductor (pins 1 thru 4) and the GND pin ofthe device (pin 5). This function generator was configured to generate a 10 V peak (20 V peak-to-peak) sinewave between pins 1-4 and pin 5. Note that the sinusoidal stimulus was applied such that no electrical currentwould flow through the copper conductor composed of pins 1-4 of this device.The frequency of this sine wave was varied from 60 Hz to 5 MHz in discrete steps. At each frequency, thestatistics feature of an oscilloscope was used to measure the voltage variations (noise) on the ACS706 outputin mV (peak to peak). The noise was measured both before and after the application of the stimulus. Transientcommon-mode voltage rejection as a function of frequency is shown in the following figure.Transient Common-Mode Voltage Rejection in the ACS706(kHz)Frequency of 20 V Peak-to-Peak Stimulus –60–55–50–45–40–35–30Tr a nsi e ntR ej ect i o n(d B)The Effect of PCB Layout on ACS706 Thermal PerformanceEight different PC boards were fabricated to characterize the effect of PCB design on the operating junction temperature of the Hall-effect IC inside of the ACS706. These PC boards are shown in the figure below. 2 oz. Cu on one side of board 2 oz. Cu on both sides of board An ACS706 device was soldered on to each PCB for thermal testing.

The ACS706 evaluation boards, for sale at the Allegro Web site On-Line Store, represent a more optimal PC board design (see photo below). On the evaluation boards, the current to be sensed flows through very wide traces that were fabricated using 2 layers of 2 oz. copper. Thermal management tests were conducted on the Allegro evaluation boards and all tests were performed using the same test conditions described in the bulleted list above. The results for these thermal tests are shown in the table below.

sgs100a工作原理
sgs100a工作原理
SGS100A是一种高性能的半导体设备，常用于电力转换和控制系统。
这种设备的工作原理主要基于半导体物理和电气工程的理论。
以下是一些基本的原理和操作步骤：
1．半导体物理基础：SGS100A的核心是半导体材料，如硅或锗。
这些材料具有独特的电学特性，如导电性能可以被外部条件（如电压或温度）所改变。
2．p-n结：SGS100A的一个关键组成部分是p-n结，它是由两种不同类型的半导体（p型和n型）形成的界面。
在一定的电压作用下，p-n结内部的电荷分布会发生变化，从而产生电流。
3．操作步骤：SGS100A的操作通常包括三个步骤：整流、开关和逆变。
a. 整流：当外部交流电通过SGS100A的整流器时，整流器将交流电转换为直流电。
这是通过半导体p-n结的单向导电性实现的。
b. 开关：SGS100A的开关功能允许电流在两个方向中的任意一个中流动。
开关的开启和关闭是由半导体材料的导电性变化来控制的。
c. 逆变：当需要将直流电转换为交流电时，SGS100A使用逆变器将直流电转换为交流电。
这是通过半导体p-n结的双向导电性实现的。
4．应用：SGS100A在许多领域都有广泛的应用，如电力转换、电机控制、电源管理、UPS系统等。
它能够提高电力转换效率，降低能源消耗，同时具有体积小、重量轻、可靠性高等优点。
以上是对SGS100A的基本工作原理的简要说明。
需要注意的是，实际的工作过程可能会因具体的应用场景和设计参数而有所不同。
