Feature Description (continued)

If the device is powered on with the magnetic field strength BRP < B < BOP, then the device output is

indeterminate and can either be Hi-Z or pulled low. During the power-up sequence, the output is held Hi-Z until

ton has elapsed. At the end of ton, a pulse is given on the OUT pin to indicate that ton has elapsed. After ton, if the

magnetic field changes such that BOP < B, the output is released. Case 3 (Figure 15) and Case 4 (Figure 16)

show examples of this behavior.
