We use these hall sensors already some time now without problems.
However we had trouble with moisture on the boards leading to all kind of erratic readings .
Now we are in the process of rugedising our software ,as to trigger alarm signals with readings that simply cannot be possible.
As such we implemented a check on the minimal/and maximal voltage that the Hall sensor can possibly deliver. If its outside this range ,something must be wrong with the board.
So we check on the Vout min and Vout max as specified in the datasheet in table 6.7 . The values being 0.2V and 1.8V respectively.
After implementing this check we get errors from perfectly good boards , we see Hall sensors giving output voltages up to 1.84V.
Are we doing something wrong here? did we make some wrong assumptions or is there something wrong with the spec in the datasheet?
