Evaluation Kit for the
PRODUCT DESCRIPTION
This evaluation board allows the ADM1191/ADM1192 devices
to be easily evaluated. The ADM1191/ADM1192 are integrated
current sense amplifiers that offer digital current and voltage
monitoring via an on-chip analog-to-digital converter (ADC)
communicated through an I
sense amplifier senses voltage across the sense resistor in the
power path via the VCC and SENSE pins.
The ADC can measure the current seen in the sense resistor
and the supply voltage on the VCC pin. An industry standard
2
I
C interface allows a controller to read current and voltage data
from the ADC. Measurements can be initiated by an I
command. Alternatively, the ADC can run continuously, and
the latest conversion can be read whenever it is required.
The devices have a SETV pin. A voltage applied to this pin is
internally compared to the output voltage on the current sense
amplifier. The output of the SETV comparator asserts when the
current sense amplifier output exceeds the SETV voltage.
When this event occurs for the ADM1191, the ALERTB output
asserts; when the event occurs for the ADM1192, the ALERT
output asserts. This alert signal can be used as a flag to warn a
microcontroller or field programmable gate array (FPGA) of an
overcurrent condition. The alert output of multiple devices can
be tied together and used as a combined alert.

EVALUATION BOARD HARDWARE
HARDWARE COMPONENTS
Main Evaluation Board
The evaluation board contains all of the circuitry necessary to
simulate power monitoring events, such as a control FET, a
sense resistor, and timing components. VR1 adjusts a variable
load; turning VR1 clockwise reduces the load resistance,
thereby increasing the load current to a maximum of 550 mA.
The load circuit is useful when evaluating the performance of the
device under varying load conditions.
5-Pin SMBus Cable
The 5-pin SMBus cable connects the main evaluation board to a
standard PC through connector J7.

COMMAND REGISTER CONTROLS
06486-017
Alert Register controls consist of four buttons you can use to
enable or disable the various alerts generated by the device
being evaluated.
The four alert types are
• ADC OC1 (analog-to-digital converter overcurrent
Alert 1): When you enable this alert, a message box appears
prompting you to enter the current limit that triggers the
alert. When you set the sense resistor to the default value
0.2 Ω, the range is 0 to 0.529 A. If a lower value sense
resistor is used, the range increases; similarly, if a higher
value is used, the range is reduced.
Press Enter after entering the value to set it. The ADC
overcurrent alert is then triggered when a current greater
than the specified level is detected by a single ADC sample.
06486-018
Figure 18. Register Control Panel
Command Register controls allow you to manage the way in
which the device reads the data. There are five toggle buttons
with which to select the data reading method and voltage range.
The voltage range is set at 14:1 by default (7:2 if the Range
button is selected). You have the option of reading the current
and voltage just once or continuously. Once you have selected
the range and reading method, click Write D ata t o Co m ma n d
Register to pass the change to the register of the device.
Note that Read Current Once and Continuous Current Read
cannot be selected simultaneously; the same rule applies to the
voltage read buttons.

• ADC OC4 (analog-to-digital converter overcurrent
Alert 4): The ADC OC4 alert is similar to the ADC OC1
alert except that it triggers only if a current greater than the
specified level is detected for four consecutive ADC samples.
This prevents a single transient event from triggering an
ADC overcurrent condition.
• Over current Alert: This alert is enabled when an over-
current condition is present.
• OFF ALERT: This alert enables the Software Off Alert.
By default, the overcurrent alert is enabled when ADC OC1,
ADC OC4, and OFF ALERT are disabled. An enabled alert is
highlighted in yellow; a disabled alert is gray in color. To enable
or disable an alert, simply select the corresponding button in

REAL-TIME GRAPHS OF VOLTAGE, CURRENT, AND POWER
On the V, I & P g ra ph s tab, you can monitor data collected
through the evaluation board using the software generated
graphs. On the tab, there are three sets of controls and graphs
corresponding to voltage, current, and power. Voltage and
current graphs are displayed using actual voltage and current
data from the device. The values for the power graph are
calculated using P = V.I.

Figure 38. Plot with Voltage Variation
Figure 39 shows that the supply voltage is constant but that the
current is changing as a result of varying the load resistance by
turning switch VR1. Turning VR1 clockwise reduces the load
resistance, thereby increasing the current; turning VR1
counterclockwise has the opposite effect. Again, notice the
variation in the power graph as the current graph changes.

EVALUATING MULTIPLE DEVICES IN PARALLEL
For the ADM1191, up to 16 unique I2C addresses can be created,
allowing you to interconnect up to 16 devices. For the ADM1192,
up to four I
connect up to four ADM1192 devices.
Each evaluation board is fitted with switches labeled A0 and A1.
A0 is used on an ADM1192 device to assign an address, via the
ADR pin, to that particular device. For the ADM1191, both A0
and A1 are used to assign up to 16 I
ensure that each device has a unique I
When interconnecting ADM1191/ADM1192 devices, you should
power each device using a bench supply of between 3.15 V and
26 V, connected to J2 (VIN) and J4 (GND).
The first evaluation board should be connected to the PC
parallel port using a 5-pin SMBus cable from the 5-pin header
labeled J7. Each board is fitted with two Minimolex connectors,
J1 and J5. To interconnect multiple boards, use the red 5-pin
Minimolex cables provided.

If more than four boards are interconnected, there are
additional tabs for the voltage, current, and power graphs. As
shown in
Figure 47, four traces are displayed in each graph, up
to a maximum of 16 traces on four graph tabs when 16 ADM1191
devices are set up in parallel.

Figure 45. Plot with Voltage Variation for Multiple Devices
As shown in Figure 45, the supply voltage is constant and the
current associated with traces is varied. The current is changed
by changing the load resistance. Turning VR1 clockwise on each
evaluation board reduces the load resistance, thereby increasing
the current, and turning VR1 counterclockwise increases the
load resistance and, thus, reduces the current.

INTERCONNECTING A COMBINATION OF ADM1191 AND ADM1192 DEVICES
ALERT/ALERTB output is not supported by the evaluation
tool when a combination of ADM1191 and ADM1192 devices
is interconnected. This is because the ADM1191 and ADM1192
have alert outputs with opposing polarity (ALERTB and
ALERT), and these output flags cannot be supported as a single
logic signal via J7 through J5 to the PC.
06486-049
Figure 49. Overcurrent Flag Indicator for Interconnected Devices with ALERT
and ALERTB Output
The Main Panel tab of the configuration tool has a different
appearance in this situation. To the right of Status Register,
there is no Overcurrent Output Flag for either the ADM1191
or the ADM1192 device.
Note that the Overcurrent Output Flag appears when
ADM1178 and ADM1191 devices are interconnected. The
reason is that both devices have the ALERTB type output.
Therefore, when interconnecting a combination of ADM1191
and ADM1192 devices, it is recommended that you use the
LEDs on the evaluation board that correspond to ALERT (D1)
and ALERTB (D5) to give a hardware alert. When an overcurrent condition is detected, the corresponding LED lights up.
To configure the evaluation board to give a hardware alert for
ALERT/ALERTB, position the jumpers as shown in
Tabl e 6.
Table 6. Jumper Positions for ALERT/ALERTB
Device Jumper
ADM1191 JP1 Position A
ADM1192 JP3 Position B
ADM1192 JP4 Position A
Note that, if an overcurrent condition occurs for the ADM1192,
you can press the on-board CLRB button to clear the alert after
the overcurrent condition is eliminated. This does not apply to
the ADM1191.
