Functional Description
2.6 Default Start-up Behavior
The magnetic thresholds exhibit a hysteresis BHYS = BOP - BRP. In case of a power-on with a magnetic field B within
hysteresis (BOP > B > BRP) the output of the sensor is set to the pull up voltage level (VQ) per default. After the first
crossing of BOP or BRP of the magnetic field the internal decision logic is set to the corresponding magnetic input
value.
VDDA is the internal supply voltage which is following the external supply voltage VDD.
This means for B > BOP the output is switching, for B < BRP and BOP > B > BRP the output stays at VQ.
