Product Description Product DescriptionUnipolar hall-effect sensor ics, often referred to as "unipolar switches, " are operated by a positive magnetic field. A single magnet presenting a south polarity (positive) magnetic field of sufficient strength (magnetic flux density) will cause the device to switch to its on state. After it has been turned-on, the unipolar IC will remain turned-on until the magnetic field is removed and the IC reverts to its off state.Sensitive hall-effect switch integrated circuitsThese hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150° C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet.Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic hall-voltage generator, temperature compensation circuitry, small-signal amplifier, schmitt trigger, and an open-collector output to sink up to 25 ma. With suitable output pull up, they can be used with bipolar or CMOS logic circuits.FeaturesWide supply voltage rangeFast response timeWide frequency and temperature rangeLong operating lifeSmall size, convenient installingOutput compatible with all digital logic familiesTypical applicationsContactless switchPosition controlSpeed measurementRevolution detectionIsolation measurementBrushless DC motorAutomotive ignitorUnipolar Switch Type Hall Effect ICModelPackageVCC(V)ICC(mA)VOL(V)IOH(uA)IO(mA)Bop(mT)Brp(mT)Bh(mT)Min.Max.AH3133TO92, SOT 23-3L4.5-246-120.2-0.4<1050611.53AH314292AH313411336AH3144225AH3141(AH441)12425AH3143(AH443)205AH3153(AH533)SOT 8912325AH3143(AH543)205AH 3621TO92, SOT 23-3L2.5-165-10151522.56Note 1: When the magnetic field S pole perpendicular points to the mark of the product front, the field is defined as B> 0.Note 2: Working magnetic field of M-type (SOT23-3L) products is subject to N pole.Note 3: More products information please visit our website or call us.Absolute maximum ratingParameterSymbolValueUnitSupply Voltage VCC 24VMagneticFlux Density BUnlimitedmTOutput OFF Voltage Vce 28VContinuous Output Current IOL 50mAOperating TemperatureRange TAAH31XXE-25~85o CAH31XXL-40~150o CStorageTemperature Range TS-55~150o CElectrical Ch a ra cteristics TA=25o C ParameterSymbolTest conditionType and ValueUnitmintypmaxSupply VoltageVCC 4.5-24VOutput Saturation VoltageVOLIout=20mA B> BOP-200400mVOutput Leakage CurrentIOHVout=24V B RP-0.110μ ASupply CurrentICCVCC=Output Open--10mAOutput Rise TimetrRL=820Ω CL=20PF-0.12-μ SOutput Fall TimetfRL=820Ω CL=20PF-0.18-μ SCC!~=4.5~24VParameterSymbolAH3142Unit mintypmaxtypmax Operate PointBOP--21-28mT Release PointBRP2----mTHysteresisBH2.5----mT Company ProfileCertificationsFAQQ: What's your MOQ?A: MOQ for each item is 1000 pcs for TO-92UA and SOT-89, 3000pcs for SOT-23Q: What's your warranty?A: All our products will be 100% tested before shipment and have lifetime warranty.Q: Can I get a Free Sample?A: You can ask our staff for applying Free Samples.Q: Are you a manufacturer ?A: Yes, we are a manufacturer.Q: How long is your delivery time?A: We have different lead times according to the quantity of the order.
