Detection Operation Glitch of SENSE Pin Voltage
The graph below shows that the pulse amplitude/ pulse width that can maintain the released condition when
the pulse of less than the detector threshold voltage was input into SENSE pin.

This graph shows the maximum pulse conditions that can maintain the released condition. Please be careful to
the sizes of the pulse width and the pulse amplitude going into SENSE pin because if they are bigger than the
sizes of the pulse width and the pulse amplitude in this graph, the reset signal may go off.
