Recommended Operating ConditionsTable 1.2. General Specification1Table 1.3. Output Pin SpecificationsTable 1.4. Magnetic SensorTable 1.5. Temperature CompensationTable 1.6. Thermal CharacteristicsTable 1.7. Absolute Maximum Ratings1Functional Description 2. Functional DescriptionThe Si7211/2/3/4/5/7 family of Hall Effect magnetic sensors digitize the component of the magnetic field in the z axis of the device (pos-itive field is defined as pointing into the device from the bottom). The digitized field is then converted to an output format of analog, PWM or SENT and presented on the output pin.Table 2.1. Part DescriptionRefer to the Magnetic Sensors Selector Guide for the two digit number after the die revision which gives more details about output, sampling frequency and other details.Data output is always unsigned. That is, half scale (V DD/2 for analog out parts, 50% duty cycle for PWM output parts and 2048 (0x800) for SENT output parts) corresponds to zero field.The parts are preconfigured for the magnetic field measurement range, idle time, temperature compensation and digital filtering and will wake into this mode when first powered. The specific configuration output type (open collector or push pull) are determined by the part number.Analog Output 3. Analog OutputFor the Si7211, the analog output is V DD/2 at zero field and goes from nearly zero at large negative field to nearly V DD at large positive field.B(mT)=(20.47or204.7)×(2×Vout Vdd−1)4- and 5-pin packages also have the option of a BISTb pin. When configured and detected low, the internal coil is turned on until the pin is detected high again. Each subsequent BISTb activation flips the polarity of the coil during BIST.For high voltage parts (Si7216), the output is ratiometric to an internally derived V DD of 5V (± 5%) so long as the input V DD is > 6 V.B(mT)=(20.47or204.7)×(2×Vout5−1)For V DD < 6 V the internally derived reference drops 1 V for each 1 V drop in V DD to the minimum recommended working voltage of 4.0 V.PWM Output Description 4. PWM Output DescriptionThe PWM output can be configured as open drain or push pull. High voltage parts can only be configured as open drain. The PWM duty cycle is factory configured and is normally set to in the range of 10 Hz to 1 KHz and is ±5%. See ordering guide for specific part num-bers..As each measurement completes, the next PWM cycle will be updated to reflect the last measurement result. The duty cycle varies from 0 to 100% where 50% duty cycle means zero field, 0 % duty cycle generally means maximum negative field (-20.47 mT or -204.7 mT) and 100% duty cycle generally means maximum positive field (+20.47 or +204.7 mT). The high portion of the PWM is output first so thatB(mT)=(20.47or204.7)×(2×Thigh−1)Thigh+TlowThe host processor should look for a variation in the magnetic field to determine the entire system is working properly.4- and 5-pin packages also have the option of a BISTb pin. When configured and detected low the internal coil is turned on until the pin is detected high again. Each subsequent BISTb activation flips the polarity of the coil during BIST.5. SENT OutputThe Si7213 and Si7215 output data in SENT (Single Edge Nibble transmission) format conforming to J2716 January 2010. All SENT output parts are configured as open collector.SENT protocol messages consist of:• A calibration/synchronization period consisting of 56 clock ticks• A status and serial communication 4-bit nibble• A sequence of up to six data nibbles• A one nibble checksum•Each nibble is 12 to 27 clock ticks•An optional delay pause pulseFigure 5.1. SENT Timing DiagramAs can be seen, each part of the sequence is determined by the timing between falling edges of the open drain sent output. First, a time of 56 clock ticks is produced so that the receiver can calibrate itself to the Si7213/5 speed. Then a total of 8 nibbles (4 bits per nibble) is produced. The edge to edge time of each nibble is 12 clock ticks for a data nibble of 0000b 13 ticks for a data value of 0001b and so on up to 27 ticks for a data value of 1111b.The nominal tick time has been standardized at 5 μsec (±5%) however this is configurable.5.1 tSENT Status NibbleIn the Si721x the four bit status nibble is defined as follows:•Bit 3 and Bit 2 always transmitted as zeroes (No serial message support)•Bit 1 and Bit 0•00 Normal; No error condition•01 Error condition•10 Positive field BIST active•11 Negative field BIST active5.2 SENT Data NibblesThe Si7213 and Si7215 are configurable to support a variety of options. The standard option follows J2716 A.3 where:For magnetic field, 3 nibbles are put together for a total 12 bit data word with values that can range from 0 to 4095. For magnetic field data, 2048 corresponds to zero field. The Si7213 can be configured for ± 20.47 mT full scale or ± 204.7 mT full scale. On the 20.47 mT full scale 1 LSB is 0.01 mT and on the 204.7 mT full scale 1 LSB is 0.1 mT.5.3 CRC CalculationThe CRC is calculated based on the 6 data nibble according to x4 +x3 + x2 + 1 with a seed value of 0101 as per the recommendations in J7216 section 5.4.2.2. The legacy CRC calculation is not supported.5.4 SENT Pause PulseThe Si7213 and Si7215 are configurable for a pause pulse that is 12 ticks low, 256 ticks wide. However, the standard offering is no pause pulse.5.5 SENT Frame RateFor the standard offering with no pause pulse, each message will be 154 to 270 ticks in length. At a tick time of 5 μsec this is 770 to 1350 μsec. This gives an average frame rate of approximately 1 msec for the standard tick time of 5 μsec. Conversion start is synchronized to the start of the synch pulse and is normally completed before the synch pulse completes so the data that is reported is the data obtained during the synch pulse time.5.6 BIST Activation During SENT OperationFor 3-pin packages BIST can be activated by holding the output pin low for the entire message.Once BIST is activated SENT messages resume 12 ticks after the SENT IO pin is detected high. Eight positive field BIST messages are followed by eight negative field BIST messages followed by a return to normal messages.The nominal magnetic field output of the on-chip generator varies with coil current. The coil current varies with the coil resistance and power supply voltage, so the nominal magnetic field output varies according to:Bout = BperVnom x VDDBperVnom is 1.6 mT/VThis can be used to calculate the expected magnetic field from the test coil for a given V DD. This is somewhat temperature dependent, so the actual measured field will vary according to the accuracy of the part as well as temperature. Generally, as the coil is turned on and off the measured variation in field should be within ±25% of expectation based on the calculated field generation.The host processor should look for a variation in the magnetic field output to determine the entire system is working properly.The 4- and 5-pin packages also have the option of a BISTb pin. When configured and detected low, the internal coil is turned on until the pin is detected high again. Each subsequent BISTb activation flips the polarity of the coil during BIST.6.

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.

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.

The results for these thermal tests are shown in the table below.

霍尔传感器用法
一、霍尔电流电压传感器、变送器的基本原理与使用方法1.霍尔器件霍尔器件是一种采用半导体材料制成的磁电转换器件。
如果在输入端通入控制电流IC ,当有一磁场B穿过该器件感磁面,则在输出端出现霍尔电势VH。
如图1-1所示。
霍尔电势VH 的大小与控制电流IC和磁通密度B的乘积成正比,即:VH=KHICBsinΘ霍尔电流传感器是按照安培定律原理做成,即在载流导体周围产生一正比于该电流的磁场,而霍尔器件则用来测量这一磁场。
因此,使电流的非接触测量成为可能。
通过测量霍尔电势的大小间接测量载流导体电流的大小。
因此,电流传感器经过了电-磁-电的绝缘隔离转换。
2.霍尔直流检测原理如图1-2所示。
由于磁路与霍尔器件的输出具有良好的线性关系,因此霍尔器件输出的电压讯号U0可以间接反映出被测电流I1的大小,即:I1∝B1∝U我们把U0定标为当被测电流I1为额定值时,U等于50mV或100mV。
这就制成霍尔直接检测(无放大)电流传感器。
3.霍尔磁补偿原理原边主回路有一被测电流I1,将产生磁通Φ1,被副边补偿线圈通过的电流I2所产生的磁通Φ2进行补偿后保持磁平衡状态,霍尔器件则始终处于检测零磁通的作用。
所以称为霍尔磁补偿电流传感器。
这种先进的原理模式优于直检原理模式,突出的优点是响应时间快和测量精度高,特别适用于弱小电流的检测。
霍尔磁补偿原理如图1-3所示。
从图1-3知道:Φ1=Φ2I1N1=I2N2I2=NI/N2·I1当补偿电流I2流过测量电阻RM时,在RM两端转换成电压。
做为传感器测量电压U0即:U=I2RM按照霍尔磁补偿原理制成了额定输入从0.01A~500A系列规格的电流传感器。
由于磁补偿式电流传感器必须在磁环上绕成千上万匝的补偿线圈,因而成本增加;其次,工作电流消耗也相应增加;但它却具有直检式不可比拟的较高精度和快速响应等优点。
4.磁补偿式电压传感器为了测量mA级的小电流,根据Φ1=I1N1,增加N1的匝数,同样可以获得高磁通Φ1。
