QUAD-SUPPLY POWER GOOD INDICATOR
The enable output of the simple sequencers is equivalent to an
AND function of V
IN
and ENIN. ENOUT is high only when the
voltage at V
IN
is above the threshold and the enable input
(ENIN) is high as well. Although ENIN is a digital input, it can
tolerate voltages as high as 22 V and can detect if a supply is
present. Therefore, a simple sequencer can monitor two supplies
and assert what can be interpreted as a Power Good signal
when both supplies are present. The outputs of two ADM1085s
can be wire-ANDed together to make a quad-supply Power
Good indicator.

SEQUENCING WITH FET SWITCHES
The open-drain outputs of the ADM1085 and ADM1087 can
drive external FET transistors, which can switch on power-
supply rails. All that is needed is a pull-up resistor to a voltage
source that is high enough to turn on the FET.
