Power-Good Detection and PG_ Outputs
The PG_ output for a given channel is asserted when
the voltage at MON_ is between the undervoltage and
overvoltage critical limits. The status of the power-good
signals is maintained in register status3[3:0]. A value of
1 in any of the pg[] bits indicates a power-good condi-
tion, regardless of the POL setting, which only affects
the PG_ output polarity. The open-drain PG_ output can
be configured for active-high or active-low status indi-
cation by the state of the POL input (see Table 30).
The POL input sets the value of bit 5 of the status3 reg-
ister, which is a read-only bit; the state of the POL input
can be changed at any time during operation and the
polarity of the PG_ outputs will change accordingly.
The assertion of the PG_ output is delayed by a user-
selectable time delay of 50ms, 100ms, 200ms, or
400ms (see Tables 31a and 31b).
