Micropowr hall sensor ah3662 Hall sensor Hall switch Features Micropower designing; Rated supply voltage , 2.4 v ~ 5.5 v; Omnipolar operating, no , nor , spole 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 8, w when the power supply is 2.75v; Built-in pull-up resistor; Products meet the eu Rohs instruction 2011/65 / eu and reach regulations 1907/2006 / eu requirements. Outline Ah3662 is a kind of high sensitivity omnipolar micropower hall sensor. The special designing circuit enable the sensor has omnipolar (no , sor , npole) magnetic field excitation function, excellent positive and negative switch symmetry, and bitty average power consumption current. When the magnet (no , sor , npole) is closed to sensor, , , the sensor outputs low level; when the magnet is far away from sensor the sensor outputs high level.
