Micropower Omnipolar Hall Sensor AH3661

Micropower Omnipolar Hall Sensor AH3661 Hall Sensor Hall Switch 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 201165 EU and REACH regulations 19072006 EU requirements. AH3661 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, excellent positive and negative switch symmetry, and bitty average power 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.
