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(∣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: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
The chip has built-in awake/sleep clock control circuit, and its awake/sleep period time is shown in the figure.Limit Parameter
Electrostatic Grade
Under human being mode, the Electrostatic compression is large than ±6kV.
Operating Condition
Electrical Characteristc
Magnetic Characteristic
Test condition:VCC1 = VCC2 =2.75V,IO = 1 mA
Note 1: Unit is mT, 1mT=10Gs
Note2: When the "S" Pole of the magnetic field is vertical to the front mark of product, we call the magnetic field B>0.
