Evaluation Kits for ADM1186 Quad
Sequencer and Monitor
EVAL-ADM1186
FEATURES
4 on-board variables supplies with LEDs to show status
LEDs to show power good, fault, and sequence done (main
evaluation kits only)
Switchable capacitors to set time delays (main evaluation
kits only)
Manual fault push switch
Single step mode
Multiple boards can be cascaded for more than four supplies
(EVAL-ADM1186-1EBZ only)
PRODUCT DESCRIPTION
The ADM1186-1 and ADM1186-2 can be used to turn on and
off four supplies in sequence under the control of a state machine,
and can monitor the supplies to ensure that they are above a
user defined undervoltage (UV) threshold. If any supply drops
below the UV threshold, a fault occurs and the state machine
turns all the supplies off.
GENERAL DESCRIPTION
There are two types of evaluation kits for the ADM1186-1
and ADM1186-2. The main evaluation boards are intended for
standalone operation of the devices with just an external mains
power supply. They provide all the on-board supplies, controls,
and status indicators necessary to operate the device. The
micro-evaluation boards are intended to allow the ADM118-1
or ADM1186-2 to be easily used as part of a bench prototype,
and include the minimal set of components.
The evaluation kits for each device allow a user to perform
controlled up and down sequences of four supplies. The
main evaluation kits allow simulated fault conditions on
each on-board supply or on a control signal. All kits provide
the ability to single-step and observe the behavior of the state
machine during the power-up and power-down sequence.
A single ADM1186-1 can control four supplies, but it is possible
to join multiple devices and boards together to support cascaded
up and down sequences of eight, 12, or more supplies. The main
ADM1186-1 evaluation board supports a daisy-chain
connection to demonstrate this feature.
EVALUATION KIT CONTENTS
The EVAL-ADM1186-1EBZ and EVAL-ADM1186-2EBZ
evaluation kits contain an evaluation board, along with some
samples of the ADM1186-1 or the ADM1186-2 parts.
The EVAL-ADM1186-1MBZ and EVAL-ADM1186-2MBZ
micro-evaluation kits contain only an evaluation board.
For all types of evaluation kit, an ADM1186-1 or ADM1186-2
device is present and soldered to the board.

EVALUATION BOARD OPERATION
POWER REQUIREMENT
Setting Voltage-Detection Levels
The evaluation board requires a supply rail of 5 V, which can
be provided in one of two ways: either a dc supply of 5 V can
be directly connected to the terminal block, J1 with polarity as
marked on the PCB, or a 9 V dc supply can be connected to
the J3 barrel jack connector, which is then regulated down.
The center of the barrel jack connector is ground.
The input pins, VIN1 to VIN4, monitor 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 3.3 V rail is 5% below its nominal
value. For example, if R1 is 100 kΩ and R2 is 23.7 kΩ, a voltage
level of 3.13 V corresponds to 0.6 V at the VIN1 pin, as shown
in Figure 3.
A switch, S1, selects which of the two supply options (jack
or term) is used by the board. At no time should a supply
connection be made to both J1 and J3.

GETTING STARTED
This section demonstrates the basic operation of a main evaluation board, performing a simple up and down sequence. The
detailed operation and configuration of the board is covered
in the following sections.
To configure a single board to perform an up and down
sequence, use the following steps:
1.
2.
3.
4.
5.
Set S2 to the down position. Set the S3 to S7 switches to the
Seq position. S3 is present only on EVAL-ADM1186-1EBZ.
Set switch banks S8 to S12 such that only Switch Position 2
on each bank of switches is on. S8 is present only on EVALADM1186-1EBZ.
On EVAL-ADM1186-1EBZ, ensure that jumpers are fitted
on J8 to J10.
Ensure that jumpers are fitted in positions J4-A, J5-B, and
J6-B. Only J4 is present on EVAL-ADM1186-2EBZ.
Turn VR1 to VR4 so that they are fully clockwise.
Connect an appropriate supply to either J1 or J3 and set
Switch S1 accordingly.
The D1 and D2 LEDs should be on. Change Switch S2 to the
up position to start an up sequence. The four supplies turn
on, shown by LEDs D3 to D6. The PWRGD (power good)
and SEQ_DONE (sequence done) LEDs, D7 and D8, are also
turned on at the end of the up sequence. Setting S2 to down
reverses the sequence, turning off the LEDs.

When multiple EVAL-ADM1186-1EBZ boards are cascaded
together, power needs to be applied to a single board. Switch S1
must be set to the same position on all boards, depending on
whether the terminal block or barrel jack is in use. This should
be done before power is connected.
Figure 3. Setting the Undervoltage Threshold with an
External Resistor Divider
Board Supplies
The board supply of 5 V is used to generate the four rails monitored by VIN1 to VIN2. The four other rails are nominally 3.3 V,
2.5 V, 1.8 V, and 1.5 V, but can be varied by about ±10% using
the variable resistors VR1 to VR4, respectively. This range is
sufficient to allow the user to set a supply above or below the
UV level to simulate undervoltage faults during a sequence or
once powered on.
Capacitor Timing and Single Stepping
The ADM1186-1 provides five timing pins, four used for
sequence delays and one for a blanking time. The ADM1186-2
provides four timing pins, three used for sequence delays and
one for a blanking time. A capacitor on each pin sets the time
delay for a given state during an up or a down sequence.
The evaluation boards provide three fixed value capacitors for
each sequence delay that can be individually switched in or out,
as required, using S8 to S11 (S8 is found only on EVAL-ADM11861EBZ). The capacitor values fitted are 10 nF, 100 nF, and 1 μF,
giving approximate delay times of 1 ms, 10 ms, and 100 ms.
The evaluation boards provide three fixed value capacitors
for the blanking delay that can be individually switched in or
out, as required, using S12. The capacitor values fitted are 10 nF,
47 nF, and 100 nF, giving approximate delay times of 1 ms, 5 ms,
and 10 ms.
Rev. 0 | Page 9 of 24
EVAL-ADM1186
PIN 1
There is also provision for user capacitors to be fitted to the
board that may be switched in for additional sequence or
blanking delay time options. For all capacitors, the duration
of the time delay is defined by the following formula:
Refer to the relevant state machine diagram in the ADM1186
data sheet for the details of when the capacitors are used during
the power-up and power-down sequences.
Manual Fault Generation
The EVAL-ADM1186-1EBZ provides a push switch, S13, that
can be used to generate a fault condition by bringing the FAULT
line low for as long as the switch is pressed. While S13 is pressed,
the D9 LED is lit to indicate a fault condition.
The delay control switches can be used to pause the state machine
and examine its behavior under various fault conditions. For
example, setting the Delay 2 control switch to hold prevents
the state machine from advancing to the ENABLE OUT2
state. This allows a user to simulate a UV condition on the 3.3 V
supply in the Delay 2 state that is otherwise difficult to achieve.

The S3 to S7 switches are set to the sequence position for normal
operation (S3 is found only on the EVAL-ADM1186-1EBZ).
Setting a switch to the hold position grounds the timing pin,
preventing the capacitor from charging and effectively pausing
the state machine.
SEQ_DONE_N
Associated with each group of capacitors on a timing pin is a
switch that can be used to hold the state machine in a specific
state. This function allows the user to single-step through an
up or down sequence, and manually control when the next
state change occurs.

Figure 4. Pin Connections for the Cascade Connectors on Board N
Figure 5 shows how boards should be connected in cascade and
the order in which the twelve supplies are turned on, from 1 to
12. In the power down sequence, the order is reversed so Supply
12 is turned off first and Supply 1 is turned off last.
There is a pair of jumpers on EVAL-ADM1186-1EBZ that needs
to be set to connect the sequence up and down control signals.
Jumper J5 and Jumper J6 should be set according to Table 3.
For example, Board A would have J5 in Position B and J6 in
Position A. When all boards are configured, Switch S2
on Board A is able to control the up and down sequence for all
cascaded boards.

The ADM1186-1 provides additional pins and functionality
that enable multiple devices to be cascaded, while still maintaining a controlled power-up and power-down sequence.
J11
The J2 and J11 connectors are used to daisy-chain the EVALADM1186-1EBZ boards to cascade multiple devices. When
connecting the boards together the order is important as this
sets the place in the power-up/power-down sequence. The
pinouts for the two connectors used for cascading boards are
shown in Figure 4.

The EVAL-ADM1186-1EBZ supports the cascading of multiple
boards so that the behavior of multiple ADM1186-1 parts
controlling eight, 12, 16, or more supplies can be demonstrated.
Figure 5. Connecting Multiple EVAL-ADM1186-1EBZs in Cascade
Rev. 0 | Page 10 of 24
EVAL-ADM1186
Jumper J8 and Jumper J10 allow the isolation of the PWRGD
and FAULT signals to individual boards. When the jumpers
are fitted, the PWRGD or FAULT signals of each board are
connected to the PWRGD or FAULT bus.
If the PWRGD signals from all the boards are joined to the
PWRGD bus, then the PWRGD signal is active only if all
supplies are above their UV threshold levels.
If the FAULT signals are all joined to the FAULT bus, a fault on
any one board causes all other devices to enter their fault
handler states as well. When multiple ADM1186-1 parts are
used in cascade, their FAULT pins are typically connected together
to ensure that the power-up and power-down sequence works
correctly.
Finally, Jumper J7 and Jumper J9 are used to connect pull-up
resistors to the PWRGD and FAULT pins on each board. The
pull-up resistors are connected to the VCC supply rail, selected
by J4, for a given ADM1186-1. If multiple PWRGD or FAULT
pins are connected together, particularly if the ADM1186-1 devices
are being powered from different supply voltages, then only one
J7 or J9 jumper should be fitted on all the boards in cascade.
MICRO-EVALUATION BOARD
The micro-evaluation boards can be used to easily create bench
prototypes of a power system. The ADM1186 micro-evaluation
boards provide all the minimum components necessary to
sequence and monitor four external dc-to-dc power modules
or LDOs.
Each micro-evaluation board provides precision resistors for
scaling to monitor 3.3 V, 2.5 V, 1.8 V, and 1.5 V rails, and capacitors to set the sequencing and blanking delays. A pull-up
resistor is also provided on each open-drain output to ensure
correct operation.
A bank of switches is provided to enable the single-step
operation of the state machine. These switches operate in
the same ways as the Delay x control switches on the main
evaluation boards. Turning on a switch grounds a time
capacitor and holds the state machine in the given state
if that capacitor is being used to control a time delay.
One of the switches on the EVAL-ADM1186-1MBZ is
connected to the FAULT line and can be used to generate
a fault condition, if required.
