QUAD-SUPPLY POWER GOOD INDICATOR
The enable output of the Simple Sequencers is equivalent to an
AND function of V
the voltage at V
(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-AND’ e d 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 that 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.
