3-wire μPower Low Voltage Hall Effect Latch/Switch/Omnipolar
The MLX92216/17 is a monolithic magnetic sensor IC utilizing a Hall Effect sensor technology. It has 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 EN 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. The MLX92216/17 can be selected with various functions: magnetic thresholds, magnetic functions and sleep times.

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.
