Product Description Features Micropower designing.Rated supply voltage 2.4 V ~ 5.5 V;Omnipolar operating, no "N" or "S" pole in excitation magnetic field, high magnetic sensitivity, highly symmetry in positive and negative magnetic switch point.Built-in dynamic imbalance voltage compensition circuit, high temperature stability, Small temperature drift in switch point, resistant to mechanical stress and thermal stress, the power consumption is only 8μW when the power supply is 2.75V.Products meet the EU RoHS instruction 2011/65 / EU and REACH regulations 1907/2006 / EU requirementsOutlineAH3663 is a kind of high sensitivity omnipolar micropower Hall sensor. The special designing circuit enable the sensor has omnipolar (no "S" or "N" pole) magnetic field excitation function, excellendt positive and negative switch symmetry, and bitty average powr consumption current. When the magnet (no "S" or "N" pole) is closed to sensor(∣B∣≥∣Bop∣),the sensor outputs low level; when the magnet is far away from sensor ∣B∣≤∣Brp∣), the sensor outputs high level. Stable Hysteresis(Bhx =∣Bopx- Brpx∣)ensure the sensor's stable switch status, the sensor's magnetic and electric transfer characteristic curve is shown as the figure:The sensor chip has voltage regulators, Hall-voltage generator, dynamic imbalance voltage compensator, temperature compensator, awake/sleep controller, differential amplifier, Schmitt trigger, logic controler and open collector output driver circuit unit etc. Sleep Period The chip has built-in awake/sleep clock control circuit, and its awake/sleep period time is shown in the figure.Limit ParameterParametersymbolMin.Max.UnitStorage Temp.Ts-55150oCSupply VoltageVCC2.47VPermitted Power consumption pd-300mWMagnetic InductionBunlimitedunlimitedmTOutput CurrentIO-5mA Electrostatic GradeUnder human being mode, the Electrostatic compression is large than ±6kV.Operating ConditionParameterSymbolMin.Max.UnitSupply VoltageVCC2.45.5VOperating Temp.Ta-4085oCOutput CurrentIO-5mA Electrical CharacteristcParamaterSymbolTest ConditionTyp.MaxUnit Output Low Level VOLVCC1= VCC2=2.75V, IO=1mA,B≥BOP0.10.25V Awake power consumption current IAWKAwake,VCC1=2.75V,Vo Open circuit 3 5 mASleep power powr consumption current ISLPSleep,VCC1=2.75V,Vo Open circuit24μA Average Power Consumption Current IAVGVCC1=2.75V,Vo Open circuit69μA Awake TimetAWVVCC1= 4V,RL=200Ω,Vo Open circuit125150μs PeriodtPVCC1= 4V,RL=200Ω,Vo Open circuit6080ms Duty FactorfdVCC1= 4V,RL=200Ω,Vo Open circuit0.1-% Magnetic CharacteristicTest condition:VCC1 = VCC2 =2.75V,IO = 1 mAParameter SymbolMin.Typ.Max.S pole Operate PointBOPS-34N Pole Operate PointBOPN-4-3-S Pole Release PointBRPS0.51.5-N Pole Release PointBRPN--1.5-0.5Hysteresis∣BOPX - BRPX∣BHX-12 Note 1: Unit is mT, 1mT=10GsNote2: When the "S" Pole of the magnetic field is vertical to the front mark of product, we call the magnetic field B>0.
