Quad Voltage Monitor and Sequencer Evaluation Kit
FEATURES
GENERAL DESCRIPTION
Evaluation kit for the ADM1185 quad voltage monitor and
sequencer
6 LEDs indicate power supply status, providing a clear visual
indication of the power-up sequence
Dedicated power and enable/disable switches
On-board test points allow examination of the ADM1185’s
operation
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 powergood signal (PWRGD).
EVALUATION KIT CONTENTS
ADM1185 main evaluation board

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.

EVALUATION BOARD OPERATION
the voltage on pin, VIN1, reaches 0.6 V, OUT1 asserts after a
190 ms delay. When this occurs, the open-drain output switches
high, and the external pull-up resistor pulls the voltage on the
regulator enable pin above its turn-on threshold, turning on the
output of the regulator.
ADM1185 SAMPLES
Two loose ADM1185 samples have been included in the
evaluation kit. Place a single sample in the socket before
powering on the evaluation board.
POWERING THE EVALUATION BOARD
There are two methods of powering the EVAL-ADM1185EBZ,
either by connecting a 9 V power supply through J3 or by
connecting a bench supply through J1 (the 9 V and ground
leads must be connected separately). When using a 9 V power
supply, make sure to switch S2 to the 9 V position; alternatively,
when using a bench supply, switch S2 to the VCC position.
SETTING VOLTAGE-DETECTION LEVELS
Each of the ADM1185’s input pins, VIN1 to VIN4, monitors
one of four supply voltages. The VIN1 pin monitors the 3.3 V
rail. An external resistor divider scales this voltage down for
monitoring at the VIN1 pin. The resistor ratio has been chosen
so that the VIN1 voltage is 0.6 V when the main voltage rises to
the preferred level at startup. For example, if R1 is 130 k Ω and
R2 is 33 kΩ, a voltage level of 2.97 V corresponds to 0.6 V at the
VIN1 pin, as shown in Figure 2.

Similar external resistor divider networks are also implemented
on VIN2 to VIN4.
THEORY OF OPERATION
OUT1 is an open-drain, active high output and is connected to the
enable pin of Regulator U1. Before the voltage on VIN1 reaches
0.6 V, OUT1 is switched to ground, disabling the regulator. When
The 2.5 V output of this regulator begins to rise. This is detected
by Input VIN2. When VIN2 sees the 2.5 V rail rise above its
threshold point, it asserts OUT2, turning on Regulator U2. The
same scheme is, in turn, implemented on the other input and
output pins.
After the final supply, 1.5 V, turns on, the outputs (OUT1 to
OUT3) are logically AND’ed together to generate a system
power-good signal (PWRGD). There is an internal 190 ms delay
associated with the assertion of the PWRGD output.
SIMULATING A POWER-UP SEQUENCE
Each of the monitored inputs is adjustable using one of the four
rotary switches, VR1 to VR4. By turning each rotary switch
clockwise, the associated input voltage is reduced. LEDs provide
a visual indication of the status of each of the four inputs and
the system PWRGD signal.
Before switching on the power supply, only the red LED, D6,
lights up, indicating that a power supply is connected to the
board. Begin with all four rotary switches turned fully anticlockwise. Switch the power supply on using Switch S1. Because
all four rotary switches are in the anticlockwise position, all four
yellow input LEDs, D1 to D4, light up. After a delay of 190 ms,
the green PWRG signal LED, D5, also lights up to indicate that
the ADM1185 is in the power-good state.
OBSERVING FAULT CONDITIONS
DURING POWER-ON
During power-up, the LEDs provide the user with a clear visual
indication of each of the four supplies. If one or more of the
supply voltages are below their associated threshold voltages,
the power-good state is not asserted, and the green PWRGD
LED is not turned on.
Rev. 0 | Page 5 of 12
UG-288
Evaluation Board User Guide
If all four supply voltages are above their associated threshold,
PWRGD asserts and the logical core latches into a different
mode of operation. If the 3.3 V supply monitored by VIN1
faults while the device is in the power-good state, the PWRDG
output is deasserted and all of the outputs are immediately
turned off. If a supply monitored by VIN2 to VIN4 fails, the
PWRGD output is deasserted, but the other outputs are not
deasserted.
Fault conditions can be investigated by using the four rotary
switches, VR1 to VR4. By turning a rotary switch clockwise, the
associated input voltage is reduced.
Rotary Switch VR1 controls the voltage at Input VIN1. As VR1
is turned clockwise, this voltage is reduced. When the voltage at
Input Pin VIN1 drops below 0.6 V, OUT1 is switched to
ground, disabling Regulator U1. In addition, VIN2 can no
longer detect the 2.5 V supply and, in turn, OUT2 and OUT3
are deasserted. As a result, the PWRGD output is also
deasserted. The LEDs clearly indicate the status of the four
voltage supplies and PWRGD.
Similarly, if PWRGD has been asserted and one of the rotary
switches, VR2 to VR4, is turned clockwise, reducing the voltage
at the associated input pin to below 0.6 V, the PWRGD output is
deasserted, but the other outputs are not deasserted. The LEDs
provide a clear indication of the status of each of the inputs and
PWRGD.
ADDITIONAL DELAYS
It is possible to introduce additional delays by connecting a
capacitor to the input pins, VIN1 to VIN4. For example if a
capacitor is placed on the VIN2 pin, the rise of the voltage on
that pin slows, effectively setting a time delay between the 2.5 V
rail powering up and the next regulator becoming enabled. The
S3, S4, S5, and S6 switches conveniently allow the user to
introduce time delays to each of the four inputs.
