ADM1185
VOLTAGE MONITORING AFTER POWER-ON
Once PWRGD is asserted, the logical core latches into a different
mode of operation. During the initial power-up phase, each
output directly depends on an input (for example, VIN3 asserting
causes OUT3 to assert). When power-up is complete, this
function is redundant.
Once in the PWRGD state, the following behavior can be observed:
If the main 3.3 V supply monitored via VIN1 faults in the
power-good state, the PWRGD output is deasserted to
warn the downstream controller. All outputs (OUT1 to
OUT3) are immediately turned off, disabling all locally
generated supplies.
If a supply monitored by VIN2 to VIN4 fails, the PWRGD
output is deasserted to warn the controller, but the other
outputs are not deasserted.

Figure 20 and Figure 21 are waveforms that highlight the
behavior of the ADM1185 under various fault situations during
normal operation (that is, in the mode of operation after
PWRGD is asserted).
