Product Description Features and BenefitsDigital output, omnipolar latchStable over the entire temperature rangeLow operating voltage range: 2.5V ~ 5.5VStrong resistance to mechanical stressNon-contact output, safety and reliableOperating temperature range: -40oC ~ 85oCTO-92UA and SOT-23-3L package optionsDeveloped according to the EU RoHS and REACHApplication ExamplesAutomotive electronics, Consumer electronics and Industrial electronicsWater flow sensingLiquid level detectionPosition sensingHand-held equipment (Cellphone, Pan-Tilt, Notebook, etc.)Contactless key/buttonBluetooth headsetDoor latch systemGeneral DescriptionThe AH3661 is a digital omnipolar-latch Hall IC with single output. It has good temperature stability and operates over a temperature range of -40°C to 85°C with latch function.The AH3661 Hall-effect sensor includes the following on a single silicon chip: reverse voltage protector, voltage regulator, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and open-drain output driver, etc.The AH3661, produced with CMOS technology, is asked for lower supply voltage and less power supply. It is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.Low Average PowerInternal timing circuit activates the IC for 45 μs and deactivates it for the remainder of the period (45 ms). A short "awake" time allows for stabilization prior to the sampling and data latching on the falling edge of the timing pulse. The output during the "sleep" time is latched in the last sampled state. The supply current is not affected by the output state.
