Note: The output of SS1881 will be switched after the supply voltage is over 2.2V, but the magnetic characteristics won't be normal
until the supply is over 2.5V.

The SOT-23 device is reversed from the UA package. The SOT-23 output transistor will be turned on(drops low) in the presence of a
sufficiently strong North pole magnetic field applied to the marked face and turned off(hoists high) in the presence of a sufficiently
strong South pole magnetic field.
