8.3ACWarning

STATUS

Optional

This is an output signal from the power supply which provides a warning to the system that the power supply has lost its AC input. This signal also provides a signal to synchronize the turn on of multiple power supplies. At turn on, this signal is pulled LOW when the supply’s internal bulk voltage has reached a level that allows it to turn on. At turn off ACWarning goes HIGH when the internal bulk voltage drops low enough. The characteristics of the ACWarning signal is shown in Table 22: ACWarning Signal Characteristics. Refer to Figure 5 for timing diagram.
