Hall-effect switch Ultra low power consumption
These sensors have an integrated logic for automatic Sleep/Awake sequencing enabling 1μA average current consumption without any action from the user (depending on the selected product). During the Awake state the chip is comparing the applied magnetic field to the predefined magnetic thresholds and updates its output accordingly.
By using the enable pin (available on MLX92217), the user can further reduce the current consumption of the chip by disabling the automatic Sleep/Awake logic and the related analog blocks. During Sleep or Disable state the OUT state remains unchanged regardless of the magnetic field. The OUT state will be refreshed during the next Enable/Awake period.
