Product Description Features and BenefitsDigital output, omnipolar switchQuickly respond to changes in magnetic fieldWide operating voltage range: 2.5V ~ 22VStrong resistance to mechanical stressNon-contact output, safety and reliableOperating temperature range: -40oC ~ 125oCTO-92 and SOT-23-3L package optionsDeveloped according to the EU RoHS and EU REACHApplication ExamplesAutomotive electronics, Consumer electronics and Industrial electronicsWater flow sensingLiquid level detectionPosition SensingSpeed SensingContactless key/buttonBluetooth headsetDoor latchsystemGeneral DescriptionThe AH3931 is a digital omnipolar Hall switch. The device includes a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short circuit protected open-drain output to sink up to 25 mA. An on-board regulator permits operation with supply voltages of 2.5 to 22 V. The advantage of operating down to 2.5V is that the device can used in 2.5V applications or with additional external resistance in series with the supply pin for greater protection against high-voltage transient events.The AH3931, 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-92 (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.
