GENERAL DESCRIPTION
The EVAL-ADM1185EBZ evaluation kit demonstrates how the
ADM1185 can provide quad voltage monitoring and
sequencing in multiple supply systems.
The ADM1185 monitors four separate voltage rails, turns on
three regulators in a predefined sequence, and generates a
power-good signal when all supplies are operating and stable.
LEDs provide a visual indication of the status of the main
supply voltage, each of the four inputs, and the system power-
good signal (PWRGD).
Four on-board rotary switches allow the user to investigate the
result of altering each of the monitored input voltages. The user
can simulate fault conditions during power up and while the
ADM1185 is in the power-good state.
