A1140, A1141, A1142, and A1143Sensitive Two-Wire Chopper-StabilizedUnipolar Hall Effect SwitchesA1140, A1141, A1142, and A1143features on-chip transient protection and a Zener clamp to protect against overvoltage conditions on the supply line.The output currents of the A1141 and A1143 switch HIGH in the presence of a south (+) polarity magnetic field of sufficient strength, and switch LOW otherwise, as in the presence of a weak field or a north (–) polarity field. The other two devices in the family (A1140 and A1142) have an opposite output: the currents switch LOW in the presence of a south-polarity magnetic field of sufficient strength,and switch HIGH otherwise. The other differences in the switches are their defined low current levels and magnetic switchpoints.All versions are offered in two package styles. The LH is a SOT-23W, miniature low-profile package for surface-mount applications. The UA is a three-lead ultramini SIP for through-hole mounting. Each package is available in a lead (Pb) free version (suffix, –T ) with 100% matte tin plated leadframe.

When the magnetic field is reduced to below the release point threshold, B RP , the device output goes high. The differences between the magnetic operate and release point is called the hysteresis of the device, B HYS . This built-in hysteresis allows clean switching of the output even in the presence of external mechanical vibration and electrical noise. The A1141 and A1143 devices switch with opposite polarity for similar B OP and B RP values, in comparison to the A1140 and A1142 (see figure 1).Figure 1. Alternative switching behaviors are available in the A114x device family. On the horizontal axis, the B+ direction indicates increasing south polarity magnetic field strength, and the B– direction indicates decreasing south polarity field strength (including the case of increasing north polarity).Sensitive Two-Wire Chopper-StabilizedUnipolar Hall Effect SwitchesA1140, A1141, A1142, and A1143Chopper Stabilization TechniqueWhen using Hall-effect technology, a limiting factor for switchpoint accuracy is the small signal voltage developed across the Hall element. This voltage is disproportionally small relative to the offset that can be produced at the output of the Hall sensor. This makes it difficult to process the signal while maintaining an accurate, reliable output over the specified oper-ating temperature and voltage ranges.Chopper stabilization is a unique approach used to minimize Hall offset on the chip. The patented Allegro technique, namely Dynamic Quadrature Offset Cancellation, removes key sources of the output drift induced by thermal and mechanical stresses. This offset reduction technique is based on a signal modulation-demodulation process. The undesired offset signal is separated from the magnetic field-induced signal in the frequency domain, through modulation. The subsequent demodulation acts as a modulation process for the offset, causing the magnetic field-induced signal to recover its original spectrum at baseband, while the dc offset becomes a high-frequency signal. The magnetic-sourced signal then can pass through a low-pass filter, while the modulated dc offset is suppressed. This configuration is illus-trated in figure 2.The chopper stabilization technique uses a 200 kHz highfrequency clock. For demodulation process, a sample and hold technique is used, where the sampling is performed at twice the chopper frequency (400 kHz). This high-frequency operation allows a greater sampling rate, which results in higher accuracy and faster signal-processing capability. This approach desensi-tizes the chip to the effects of thermal and mechanical stresses, and produces devices that have extremely stable quiescent Hall output voltages and precise recoverability after temperature cycling. This technique is made possible through the use of a BiCMOS process, which allows the use of low-offset, low-noise amplifiers in combination with high-density logic integration and sample-and-hold circuits.The repeatability of magnetic field-induced switching is affected slightly by a chopper technique. However, the Allegro high-frequency chopping approach minimizes the affect of jitter and makes it imperceptible in most applications. Applications that are more likely to be sensitive to such degradation are those requiring precise sensing of alternating magnetic fields; forexample, speed sensing of ring-magnet targets. For such applica-tions, Allegro recommends its digital sensor families with lower sensitivity to jitter. For more information on those devices, contact your Allegro sales representative.Figure 2.

Typical application circuitTypical Application CircuitThe A114x family of devices must be protected by an external bypass capacitor, C BYP , connected between the supply, VCC, and the ground, GND, of the device. C BYP reduces both external noise and the noise generated by the chopper-stabilization func-tion. As shown in figure 3, a 0.01 μF capacitor is typical.Installation of C BYP must ensure that the traces that connect it to the A114x pins are no greater than 5 mm in length.All high-frequency interferences conducted along the supply lines are passed directly to the load through C BYP , and it serves only to protect the A114x internal circuitry. As a result, the load ECU (electronic control unit) must have sufficient protection, other than C BYP , installed in parallel with the A114x.A series resistor on the supply side, RS (not shown), in combina-tion with C BYP , creates a filter for EMI pulses.When determining the minimum V CC requirement of the A114x device, the voltage drops across R S and the ECU sense resistor, R SENSE , must be taken into consideration. The typical value for R SENSE is approximately 100 Ω.Sensitive Two-Wire Chopper-StabilizedUnipolar Hall Effect SwitchesA1140, A1141, A1142, and A1143Power DeratingThe device must be operated below the maximum junctiontemperature of the device, T J(max). Under certain combinations of peak conditions, reliable operation may require derating sup-plied power or improving the heat dissipation properties of the application. This section presents a procedure for correlating factors affecting operating T J . (Thermal data is also available on the Allegro MicroSystems Web site.)The Package Thermal Resistance, R θJA , is a figure of merit sum-marizing the ability of the application and the device to dissipate heat from the junction (die), through all paths to the ambient air. Its primary component is the Effective Thermal Conductivity, K, of the printed circuit board, including adjacent devices and traces. Radiation from the die through the device case, R θJC , is relatively small component of R θJA . Ambient air temperature, T A , and air motion are significant external factors, damped by overmolding.The effect of varying power levels (Power Dissipation, P D ), can be estimated. The following formulas represent the fundamental relationships used to estimate T J , at P D . P D = V IN × I IN (1)ΔT = P D × R θJA (2)T J = T A + ΔT(3)For example, given common conditions such as: T A = 25°C,V CC = 12 V, I CC = 4 mA, and R θJA = 140 °C/W, then: P D = V CC × I CC = 12 V × 4 mA = 48 mW ΔT = P D × R θJA = 48 mW × 140 °C/W = 7°CT J = T A + ΔT = 25°C + 7°C = 32°CA worst-case estimate, P D(max), represents the maximum allow-able power level (V CC(max), I CC(max)), without exceeding T J(max), at a selected R θJA and T A .Example : Reliability for V CC at T A = 150°C, package UA, using minimum-K PCB.Observe the worst-case ratings for the device, specifically: R θJA = 165°C/W, T J(max) = 165°C, V CC(max) = 24 V , and I CC(max) = 17 mA.Calculate the maximum allowable power level, P D(max). First, invert equation 3:ΔT max = T J(max) – T A = 165 °C – 150 °C = 15 °CThis provides the allowable increase to T J resulting from internal power dissipation. Then, invert equation 2:P D(max) = ΔT max ÷ R θJA = 15°C ÷ 165 °C/W = 91 mW Finally, invert equation 1 with respect to voltage: V CC(est) = P D(max) ÷ I CC(max) = 91 mW ÷ 17 mA = 5 V The result indicates that, at T A , the application and device can dissipate adequate amounts of heat at voltages ≤V CC(est).Compare V CC(est) to V CC(max). If V CC(est) ≤ V CC(max), then reli-able operation between V CC(est) and V CC(max) requires enhanced R θJA . If V CC(est) ≥ V CC(max), then operation between V CC(est) and V CC(max) is reliable under these conditions.Sensitive Two-Wire Chopper-StabilizedUnipolar Hall Effect SwitchesA1140, A1141, A1142, and A1143Device Qualification ProgramEMC (Electromagnetic Compatibility) RequirementsTest NameReference Specification ESD – Human Body Model AEC-Q100-002ESD – Machine Model AEC-Q100-003Conducted Transients ISO 7637-2Direct RF Injection ISO 11452-7Bulk Current Injection ISO 11452-4TEM CellISO 11452-3Contact Allegro for information.Contact your local representative for EMC results.Sensitive Two-Wire Chopper-StabilizedUnipolar Hall Effect SwitchesA1140, A1141, A1142, and A1143Package LH, 3-Pin; (SOT-23W)Sensitive Two-Wire Chopper-StabilizedUnipolar Hall Effect SwitchesA1140, A1141, A1142, and A1143The products described herein are manufactured under one or more of the following U.S. patents: 5,045,920; 5,264,783; 5,442,283; 5,389,889; 5,581,179; 5,517,112; 5,619,137; 5,621,319; 5,650,719; 5,686,894; 5,694,038; 5,729,130; 5,917,320; and other patents pending.Allegro MicroSystems, Inc. reserves the right to make, from time to time, such de p ar t ures from the detail spec i f i c a t ions as may be required to permit improvements in the per f or m ance, reliability, or manufacturability of its products.

Cat #2153.41 Includes two 1.5 V batteries (AA or LR6), multilingual safety data sheet, user manual, and verification certificate.1. INTRODUCTION1.1. GENERALMiniFlex® sensors consist of a flexible coil connected by a shielded lead to a housing containing the signal processing electronics, powered by batteries. The flexibility of the sensors allows clamping of the conductor to be measured, whatever its shape (cable, bar, strand, etc.) and accessibility. The snap-locking coil opening/closing button allows handling while wearing protective gloves. The electronic unit can be connected to the mV AC or V AC input of a measuring instrument having an input impedance of ≥ 1 MΩ.1.2. MINIFLEX® MODEL MA114MiniFlex® MA114 single‑phase 14” (35 cm) sensor converts alternating currents ranging from 3 to 3000 A into proportional AC voltages.Flexible coil Banana plugs (2), 0.16”(4 mm) diameterSensor openingbutton OL indicator (red): indicates reading exceeds measurement rangeShielded cableSwitch to activate instrument and select sensitivity Auto Power OFF indicator (orange): auto OFF feature activatedAuto Power OFF button deactivates auto OFF feature ON indicator (green): Blinking: running on battery power Steady: running on external powerType B Micro-USBport to connect optional 5 V externalpower supply Connecting cable connecting the electronic unit to a display instrument2. OPERATION2.1. MEASUREMENT PRINCIPLEThe MA114 sensor is based on the Rogowski coil principle. This provides: very good linearity and no saturation effect (and therefore nooverheating)wide measurement dynamic, up to several kAinsensitivity to DC (measurement of the AC component of any AC + DCsignal)light weight (no magnetic circuit)2.2. OPERATION2.2.1. CONNECTING THE MA1141. Connect the output leads to a measuring instrument (for example amultimeter) having an input impedance ≥ 1 MΩ. Turn it ON and set toAC voltage measurement.2. Turn the instrument ON by turning the rotary switch to any position. The green ON indicator starts blinking.3. Press on the yellow sensor opening button to open the flexible coil.4. Place the open sensor around conductor to be measured (only one conductor in the sensor at a time). Close the coil; an audible click sounds as the coil is closed.Use individual protection equipment when measuring an uninsulated conductor carrying a high voltage.To optimize measurement, center the conductor in the coil.5. Set the switch to the range providing the best sensitivity and ensure the red OL indicator is off. (OL indicates saturation of the electronics,resulting in a measurement error.)6.Read the measurement on the multimeter, applying the readingcoefficient indicated on the label on the electronic unit corresponding tothe setting of the switch.3A~ range: 1000 mV~/A~30 A~ range: 100 mV~/A~300 A~ range: 10 mV~/A~3000 A~ range: 1 mV~/A~7.Multiply the reading by the coefficient.For example, a reading of 1 V on the measuring instrument correspondsto a current of 1V10mV/A= 100 A in the 300 A~ range.2.2.2. DISCONNECTING THE MA114Remove the flexible coil from the conductor, set the switch to OFF, and disconnect the electronic unit from the multimeter.2.2.3. AUTOMATIC POWER OFFWhen the MA114 starts up, it operates for 10 minutes, then automatically switches itself to sleep mode to save battery life. While this feature is activated, the orange Auto Power Off indicator is lit.To override automatic power off:1.With the MA114 OFF, press and hold down the Auto Power Off buttonwhile turning the sensor ON by turning the switch to any measurementsetting.2.Continue to hold down Auto Power Off for longer than 2 seconds. Theorange Auto Power Off indicator remains OFF, indicating this feature isdisabled.2.3. EXTERNAL POWER (OPTIONAL)For long‑duration measurements, you can connect the MA114’s electronic unit to line power. Remove the protection from the type B micro‑USB connector, then connect the lead. You can use any line/micro‑USB adapter that delivers 100 mA or more.The green On indicator remains lit but its brightness varies to indicate the batteries are functional. While external power supply is present, automatic power off is disabled. If external power is disconnected, the MA114 switches to battery power and automatic power off takes effect after 10 minutes.If you make long‑duration recordings, you must deactivate automatic power OFF (see § 2.2.3).The insulation between the type B micro‑USB connector and the measurement output is 1000 V CAT III or 600 V CAT IV. That makes it possible to safely connect the instrument to wattmeters with uninsulated inputs. The type Bmicro‑USB connector must not be in contact with conductors or uninsulated material at dangerous voltages.3.SPECIFICATIONS3.1.
