Product Description

  • 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 2011/65 / EU and REACH regulations 1907/2006 / EU requirements
  • Outline
  • AH3663 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, excellendt positive and negative switch symmetry, and bitty average powr consumption current. When the magnet (no "S" or "N" pole) is closed to sensor(BBop),the sensor outputs low level; when the magnet is far away from sensor BBrp), 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:The sensor chip has voltage regulators, Hall-voltage generator, dynamic imbalance voltage compensator, temperature compensator, awake/sleep controller, differential amplifier, Schmitt trigger, logic controler and open collector output driver circuit unit etc.
  • Sleep Period
