Feature Description (continued)
If the device is powered on with the magnetic field strength B_RP < B < B_OP, 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
t_on has elapsed. At the end of t_on, a pulse is given on the OUT terminal to indicate that t_on has elapsed. After t_on, if
the magnetic field changes such that B_OP < B, the output is released. Case 3 (Figure 15) and Case 4 (Figure 16)
show examples of this behavior.
