Therefore, it requir The OUT pin of these devices switches low (turns on) when a magnetic field threshold, BOP. After turn-on, the output voltage is VDSon. Note that the devic es both south and north poles to operate properly. perpendicular to the Hall sensor exceeds the operate point tches, that is, a south pole of sufficient strength towards the branded surface of the device turns the device on. The device remains on if the south pole is removed (B→0). This ry. When t op point, and allows clean switching of the output even in the presence of external mechanical vibration and electrical noise. Th eq Po RP) allows an indeterminate output state. The correct sta OP RP Th str 0mT 0mT e la latching property defines the device as a magnetic memo he magnetic field is reduced below the release point, BRP , the OUT pin turns off (goes high). The difference in the magnetic erate and release points is the hysteresis, BHYS , of the device. This built-in hysteresis prevents output oscillation near the switching e device behaves as a latch with symmetric operating and release switching points (BOP=|BRP|). This means magnetic fields with uivalent strength and opposite direction drive the output high and low. wering-on the device in the hysteresis region (less than BOP and higher than B te is attained after the first excursion beyond B or B . e SOT-23 device is reversed from the UA package.
