ISL28025 Precision Digital Power Monitor
Evaluation Kit User Guide
Introduction
ISL28025 Generic Board (ISL28025EVAL1Z)
The Precision Digital Power Monitor (DPM) Evaluation Kit is a
three evaluation board design that demonstrates the
functionality of the ISL28025. The ISL28025 is an IC with a
16-bit analog-to-digital converter (ADC), an 8-bit
digital-to-analog converter (DAC), and analog comparators that
monitor for undervoltage, overvoltage and overcurrent
conditions. The IC is serially controlled through an I2C bus. The
device abides by the PMBus standards.
The DPM Evaluation kit is accompanied by a graphical user
interface (GUI) that allows the user to configure ISL28025 for
monitoring bus voltage and current in a specific application.
The GUI has a data save feature allowing the transfer of
measurement data to another software application for
analysis.
The ISL28025 DPM evaluation kit consists of three boards; a
dongle, a generic ISL28025 board and an ISL28025
demonstration board.
Dongle Evaluation Board
(ISLUSBPWRDONGLE1Z)
The dongle board mates from a PC to the ISL28025 via a
microcontroller. The microcontroller converts USB commands
sourced from the PC to an I2C header. The I2C pins (SCL and
SDA) are connected to the right angle header at the edge of
the board. The dongle board has a circuit that converts the USB
supply voltage to 3.3V. The 3.3V supply circuit has an
ISL28022 connected to monitor the current sourced by the
supply. Each circuit has been optimized to measure 100mA at
full scale. The 3.3V supply output and the SDA and SCL lines of
the I2C bus are routed to the right angle connector.
USB DONGLE
The generic ISL28025 board is a non-configured ISL28025
that connects the analog inputs to the outside world. The
board allows a user to build a system that requires voltage,
current or power monitoring around the ISL28025. The analog
inputs (VINP, VINM and VBUS) of the ISL28025 accept input
voltages ranging from 0V to 60V. The ISL28025 allows the
user to uniquely configure the slave address via jumper
selections. The ISL28025 can be powered from a user defined
source or the 3.3V supply generated from the USB voltage. The
acceptable power supply voltage range for the ISL28025 is
from 3V to 5.5V. The external clock/interrupt pin is routed to
the outside world via a jumper selection. The maximum
measurable input differential (VINP - VINM) is ±80mV. The
differential voltage between the VINP and VINM pins can
withstand a magnitude of 60V. The differential supply
tolerance allows for the debugging of catastrophic circuit
events.
ISL28025 Demo Board (ISL28025EVAL2Z)
A peripheral circuit is required to demonstrate the functionality
of the ISL28025. The ISL28025 is paired up with a buck/boost
regulator (ISL9110) and some sample loads to measure the
current.
The buck/boost circuit allows the user to define a unique load
that connects to the regulator. All features of the ISL28025 are
available.

DPM MEASUREMENT FUNCTIONALITY
Enabling the current functional block on the DPM interface
requires the user to enter a shunt resistor value. The entered
value is stored in the DPM calibration register and is used to
calculate the current or power depending on the enabled check
box. Figure 4 illustrates the dialog box that request the shunt
resistor value when current functionality is enabled.
averages can be programmed from a single measurement to
4096 measurements.
LOOP DELAY
The loop delay field in the lower right corner of the GUI allows the
use to program a delay between measurements. When the
ISL28025 is program to fast acquisition times, the screen is
updating quickly such that the user cannot read the
measurements that is taken by the ISL28025. The loop delay
field inserts a time delay after each measurement. Allowing for a
time delay makes the measurements readable.
SINGLE MEASUREMENT CONTROL
Pressing the Meas Once button on the main panel will measure
each enabled individual channel once.

THRESHOLD AND AUXILIARY CONTROLS
Choose the Threshold selection under the ISL28025 drop down
menu that invokes the Auxiliary Control dialog box. The dialog
box allows the user to configure the threshold detectors of the
ISL28025 chip. Figure 5 shows the Auxiliary Controls Dialog Box.
The threshold levels of the analog comparators for the
overvoltage (OV), undervoltage (UV) and overcurrent conditions
(OC) are created from three 6-bit DAC. The DACs have voltage
ranges. There are two voltage ranges for the OC comparator and
six for the OV/UV comparators. The analog comparators can be
enabled and disabled by checking the enable check boxes.
AN1933.1
March 9, 2016
Application Note 1933
Depending on the voltage range selected, the voltage range for
each threshold is stated above and below each input box.
The OC analog detector detection polarity can be set via checking
the “Reverse Current Direction?” check box.
The OV detector can be converted to a temperature threshold
detector by checking the “Temperature Detect?” check box.
The outputs of the threshold comparators feed into the
SMBALERT control window. The comparator output can be routed
to the SMBALERT pins of the device via checking the respective
feed-through check box.
The default state of each comparator connects to a digital timing
filter and mask circuitry. All three comparators feed into an Or
gate to determine the status of the SMBALERT pin.
The active state polarity can be selected by checking the invert
check box of the respective SMBALERT pin.
There is one digital filter per threshold comparator. Setting the
digital filter changes the behavior for both SMBALERT pins. The
digital filter filters out aberrant responses from the analog
comparators by way of fault longevity. The device allows the user
to choose between four fault timing windows before allowing a
fault to pass to the latch bit (D flip-flop).
The mask block allows the user to determine if the fault is
passed to the Or gate.
Each SMBALERT pin can be controlled independent of
comparator circuitry by checking the force interrupt pin.
The default state of the SMBALERT2 pin is disabled. This puts the
pin state to tri-state. The SMBALERT2 pin has push-pull output
stage while the SMBALERT1 is an open drain.
EXTERNAL CLOCK ENABLE
FIGURE 5. THE WINDOW THAT CONTROLS THE ISL28025
COMPARATORS
The ISL28025 can be synchronized to an external clock to reduce
measurement noise in a system. To configure and enable the
external clock feature choose the EXTCLK selection in the
ISL28025 drop down menu. A dialog box, illustrated in Figure 8
will appear allowing the user to enable the external clock feature.
SMBALERT
Choose the SMBALERT selection under the ISL28025 drop down
menu. A window similar to the Figure 6 will appear.
FIGURE 7. THE EXTERNAL CLOCK WINDOW FOR THE ISL28025
The input bandwidth of the external clock pin is roughly 30MHz.
The external clock frequency can be divided to match the internal
system clock frequency of 500kHz. Choosing a clock division that
results in internal clock frequency close to 500kHz will guarantee
ADC acquisition times similar to the default times.

PEAK CURRENT
Choose the Current Min/Max selection under the ISL28025 drop
down menu. A window similar to the Figure 8 appears.
FIGURE 8. THE CURRENT PEAK DETECT WINDOW
The current peak detect feature reports the min and max reading
of a single sample. For example, suppose the settings for the
Vshunt input has an acquisition time of 64µs and an internal
average of 4096. The sense resistor has been digitized, such that
it enables current measurements. If the measure once button
has been pressed, the device will perform 4096 averages and
place the average value in the current register. With the current
peak detect enabled, the maximum and the minimum current
readings from the 4096 measurements are placed in the current
peak register and displayed in the window. If the measure once
button is pressed again, the Max/Min readings will reflect the
Max/Min readings for 8192 measurements. The Max/Min will
reflect the Max/Min current for all readings since the registers
have been cleared last.
Connecting Multiple ISL28025 Evaluation
Boards to a Dongle
An ISL28025 design can have 55 devices connected on a single
I2C bus. The ISL28025 Evaluation kit allows the user to cascade
up to 54 ISL28025 Evaluation Boards. The dongle uses a slave
address (0x9E) for measuring the current and voltage of the 3.3V.

SAVING DATA
The DPM software allows the user to store a set number of points
of data. Go to the menu bar of the ISL28025 DPM Demo
Software window and choose File --> Save Data. Choosing the
Save Data option will open a dialog box asking for the filename
and directory of the save path. Figure 14 is an illustration of the
dialog box.
The file name entered in the dialog box is the base name for all
files saved. A unique named file is generated for each measured
parameter (Vbus, Vshunt, Current, Power, etc...) across all active
devices. The software only saves data to a file for each measured
parameter selected. If a measured parameter is not selected,
then a file with the non-selected measured parameter is not
generated. For example, Vaux and VauxShunt are files that would
not be generated for the configuration of the DPM window shown
in Figure 14.

All saved files are comma delimited. The naming convention of
the file is< base name>_<measured parameter>_dataset. The
base name is the file name entered in the save dialog box. The
measured parameter names are vbus, vshunt, current and
power, etc.
Upon completion of the save dialog box, an input box (Figure 15)
asks for the number of points to be saved per site if the GUI is in
the Single Site Mode. Otherwise, the software will save the same
number of points for all sites in the System mode.
FIGURE 15. THE DIALOG BOX THAT ASKS THE USER TO ENTER THE
NUMBER OF DATA POINTS TO SAVE
Pressing the OK button with a valid numerical entry will begin
data collection. The numerical values changes on the main
window while the data is being recorded. The completion of data
collection will commence when all of the active measurement
numbers cease to change.
The settings of all channels should be finalized prior to invoking
the Save Data feature. The user has the option of uniquely
naming each channel and having the channel name be passed to
the column name of each respective data file. Changing the field
named “Channel Name” in Figure 10 on page 6 will change the
name of the column data.
SAVING AND LOADING THE CONFIGURATION FILES
The software allows the user to save and load the configuration
of each of the devices. To load or save a configuration, select
Load Config or Save Config under the File drop down menu. A
window will appear similar to Figure 14 that will ask for directory
information of the file to save or load.

The screen is the same as the ISL28025 generic evaluation
software plus the controls for the demo board. The Demo
Controls are illustrated as the ISL9110 group box in Figure 17.
All the controls and features discussed in the ISL28025 generic
board software are available to the user in the demo software.
The ISL28025 demo board connects a buck-boost regulator
(ISL9110) to some resistive loads. The current going into the
regulator is monitored by the Vshunt inputs (VINP, VINM) and a
shunt resistor of 0.05Ω (RSENSE1). The Vaux input measures the
regulated voltage at the load. The Vbus input measures the
voltage applied to the input of the ISL9110. The current and
power displays represent the current and power being sourced to
the regulator and load.
Press the “ON” button in the lower right hand corner to turn on
the ISL9110. The Vbus, Vshunt, Current, Power, Vaux channels
will turn on if they are not currently active.
SETTING THE REGULATED OUTPUT VOLTAGE
Press the “Set Reg V” will control a ISL23315 digital
potentiometer (DCP). The DCP is connected to the feedback
resistor of the regulator, R14. The DCP controls the gain of the
regulator and the output voltage of the regulator. Equation 1
determines the regulated output voltage.

CHANGING THE SHUNT RESISTOR VALUES
Press the “Set Res Val” button changes the values used to
calculate system current and load current as well the efficiency
readings of the system.
CHANGE THE LOAD VALUES CONNECTED TO THE
REGULATOR
If the jumper setting for the OUTPUT LOAD header is connected
between pins 1 and 2, the output of the regulator is connected to
a series of loads that are controlled by a port extender and a
series of ISL83699 switches. To connect a load to the regulator,
check the check box of the desired load.
Note: At light loads, the current measurements will have errors
due to the temperature coefficient of the resistors. The resistors
are calibrated at moderate current levels. The magnitude of
current causes the resistors to heat up resulting in a shunt
resistor value change. The resistors installed on the demo board
are 50ppm/°C TC resistors with a power rating of 0.5W.
Improving the temperature coefficient of shunt resistors or
increasing the power rating of the resistors will limit the resistor
change due to current.
(EQ. 1
The reference voltage for the ISL9110 is 0.8V. The value of R14 is
100kΩ. The value of RDCP is determined by the desired regulator
output voltage, VOUT . By entering a voltage and pressing the Vreg
button of the ISL28025 demo software, the software back
calculates the value of RDCP to set the output voltage to the
desired value.
