Note: For explaining in a simplified case, an operation time of the circuit is not counted.
The following explains the operation of the typical application circuit along number symbols shown in the timing chart.
ᶃç When input voltage (V_IN) rises above detect voltage (V_DF), output voltage (V_OUT) will be equal to input voltage (V_IN). (A
condition of high impedance exists with N-ch open drain output configurations.)
ᶄç When input voltage (V_IN) falls below detect voltage (V_DF), output voltage (V_OUT) will be equal to the ground voltage
(V_SS) level.
ᶅç When input voltage (V_IN) falls to a level below that of the minimum operating voltage (V_MIN), output will become
unstable. If In this condition, V_IN will equal the pulled-up output (should output be pulled-up.) (Input voltage, V_IN, in
the typical application circuit.)
ᶆ When input voltage (V_IN) rises above the minimum operating voltage (V_MIN) level until it achieves a release voltage
(V_DR), output keeps the ground voltage level (V_SS).
ᶇç When the input voltage (V_IN) rises above the release voltage (V_DR), output voltage (V_OUT will be equal to input voltage
(V_IN). (A condition of high impedance exists with N-ch open drain output configurations.)
ᶈç The difference between V_DR and V_DF represents the hysteresis width.
