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 DESCRIPTION
The ADM1191/ADM1192 digital power monitor evaluation
board can be controlled using the configuration tool, allowing
the device to be actively simulated through software. This
evaluation board provides an I
power supply of between 3.15 V and 26 V connected through
the J2 and J4 connectors. The latest version of the configuration
tool can be downloaded from the Analog Devices, Inc., website
www.analog.com/powermonitorsw.
Note that, when changing devices, the software should first be
shut down and the power supply to the board removed. J7 is an
2

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.

a maximum of 550 mA.
5-Pin Interconnection Cable
The interconnection cable is used for multiple evaluation board
parallel connection setup. Two or more boards can be connected in
parallel through the J1 and J5 connectors using the 5-pin
interconnection cable. Each device should be assigned to a
different address using an address pin. The maximum number
of devices that can be interconnected is four for the ADM1192
and 16 for the ADM1191.
Device Samples
Some loose samples of the device to be evaluated are included
in a samples box. A single device should be placed in the socket
before powering up the evaluation board. The device should be
oriented in the socket so that Pin 1 is in the top left corner, near
C6, as shown in
Figure 1.
