5. Start-up response
Figure 14, Figure15 show the start-up response of this IC. After rising of V_DD for this IC, V_OUT changes to the level
according to the result of the magnetic flux density judgment after 80 μs typ. is elapsed.
Thereafter V_OUT is refreshed to the level according to the result of the magnetic flux density judgment for each period
the t_CYCLE elapses.
