Outline
AH3662 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:
The sensor chip has voltage regulators, Hall-voltage generator, dynamic imbalance voltage compensator, awake/sleep controller, difference 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.
