To give a better view of the functionality,
at t2 to t3 and t4 to t5. If the dip at t4 to t5 is too short (that is, < 11 s), the internal POR
pulse will not react and will remain LOW. The internal POR starts with a 1 at t0. At t1, the
detector will see the passing of the trip level and a delay element will add another t
before it drops to 0.
The internal POR pulse will be generated whenever V
