ISL28023 Precision Digital Power Monitor
Evaluation Kit User Guide
Introduction
ISL28023 Generic Board (ISL28023EVAL1Z)
The Precision Digital Power Monitor (DPM) Evaluation Kit is a
three evaluation board design that demonstrates the
functionality of the ISL28023. The ISL28023 is an IC with a
16-bit Analog-to-Digital Converter (ADC), an 8-bit
Digital-to-Analog Converter (DAC), and analog comparators
that monitors 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 ISL28023 for
monitoring bus voltage and current in a specific application.
The GUI has a data save feature allowing the transfer of
measurement data to other software application for analysis.
The ISL28023 DPM Evaluation Kit consists of three boards; a
USB dongle, a generic ISL28023EVAL1Z board and an
ISL28023EVAL2Z demonstration board.
The generic ISL28023 board is a nonconfigured ISL28023 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 ISL28023. The analog inputs
(VINP, VINM and VBUS) of the ISL28023 accept input voltages
ranging from 0V to 60V. The ISL28023 allows the user to
uniquely configure the slave address via jumper selections.
The ISL28023 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 ISL28023 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.
ISL28023 Demo Board (ISL28023EVAL2Z)
Dongle Evaluation Board
(ISLUSBPWRDONGLE1Z)
The dongle board mates from a PC to the ISL28023 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.
A peripheral circuit is required to demonstrate the functionality
of the ISL28023. The ISL28023 is paired up with a buck
regulator (ISL85415) and some sample loads to measure the
current and efficiency calculations of the regulator to the load.
The buck circuit allows the user to define a unique load that
connects to the regulator. The user can define the switching
frequency of the regulator by programming a resistor value
into the ISL23345 digital potentiometer. All features of the
ISL28023 are available.

FIGURE 3. MAIN WINDOW OF THE ISL28023 GENERIC USER INTERFACE (GUI) CONNECTED TO THE ISL28023 GENERIC BOARD
DPM MEASUREMENT FUNCTIONALITY
LOOP DELAY
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 requests the shunt
resistor value when current functionality is enabled.
The loop delay field in the lower right corner of the GUI allows the
user to program a delay between measurements. When the
ISL28023 is programmed to fast acquisition times, the screen is
updating quickly such that the user cannot read the
measurements that is taken by the ISL28023. 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
FIGURE 4. DIALOG BOX THAT ALLOWS THE USER TO ENTER THE

FIGURE 5. THE WINDOW THAT CONTROLS THE ISL28023
COMPARATORS
The threshold levels of the analog comparators for the
overvoltage (OV), undervoltage (UV) and overcurrent conditions
(OC) are created from three 6-bit DACs. 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.
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.
SMBALERT
Choose the SMB Alert selection under the ISL28023 drop down
menu. A window similar to the Figure 6 will appear.
The outputs of the threshold comparators feed into the SMB Alert
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.

MARGIN DAC
Choose the SMB Alert selection under the ISL28023 drop down
menu. A window similar to Figure 7 appears.
FIGURE 9. THE CURRENT PEAK DETECT WINDOW
FIGURE 7. MARGIN DAC CONTROL WINDOW
The default state of the margin DAC is off, causing the DAC
output pin to be in tri-state. Enabling the margin DAC feature
requires the DAC output and DAC check boxes to be checked.
The Margin DAC is an 8-bit DAC with eight voltage ranges that
half scale voltage ranges from 0.4V to 1.2V. The user can choose
the DAC range next to the DAC Half Scale label. The min and max
input for each range is stated above and below the input box.
The Apply button sets the DAC voltage to the input voltage value
without closing the window. The OK button does the same as the
Apply button but closes the window. The cancel button does not
apply the input voltage.
EXTERNAL CLOCK ENABLE
The ISL28023 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
ISL28023 drop down menu. A dialog box, illustrated in Figure 8,
will appear allowing the user to enable the external clock feature.
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 meas 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.
EXTERNAL TEMPERATURE SENSOR
The external temperature sensor is a feature that measures the
temperature remotely from the DPM by connecting a diode to the
Aux shunt inputs. The DPM will squirt two currents to determine
the temperature of the diode.
The External Temperature sensor feature can be enabled by
checking the Ext Temp En check box in Figure 3 on page 3.
Checking the Ext Temp En check box will disable the internal
temperature sensor. The value from the external temperature
sensor is stored in the internal temperature register.
Upon enabling the external temperature sensor, an input box will
appear asking to null the temperature. The dialog box looks
similar to Figure 10.
FIGURE 8. THE EXTERNAL CLOCK WINDOW FOR THE ISL28023
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 an 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 ISL28023 drop
down menu. A window similar to Figure 9 appears.

Diodes are not very good at measuring absolute temperature but
a very good at measuring temperature change.
If Yes is selected, the reading that is reported back is the
subtraction of the null temperature and the current temperature
that was measured.

USB SUPPLIES
The ISL28023 Demo Software allows a user to build their own
board to mate with the Dongle board. The final design of the third
party board may use the dongle generated 3.3V power supply.
The user can monitor the current draw from 3.3V supply by
selecting USB Supplies under the dongle drop down menu. The
dialog box in Figure 14 will appear once the USB Supplies are
selected.
FIGURE 16. THE DIALOG BOX THAT REQUESTS WHERE TO SAVE THE
DATA FILES
FIGURE 14. USB SUPPLY WINDOW OF THE 3.3V GENERATED SUPPLY
I2C TRANSACTION
The ISL28023 Demo Software allows a user to build their own
board to mate with the dongle board. The final design may have
an I2C device incorporated into the design. The I2C transaction
selection in the dongle drop down menu allows the user to send
read and write commands to I2C devices. Figure 15 is the dialog
box that appears when the I2C transaction is chosen under the
dongle drop down menu.
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 3 on page 3.
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 17)
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 I2C TRANSACTION WINDOW
SAVING DATA
The DPM software allows the user to store a set number of points
of data. Go to the menu bar of the ISL28023 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 16 is an illustration of the
dialog box.
FIGURE 17. THE DIALOG BOX THAT ASKS THE USER TO ENTER THE
NUMBER OF DATA POINTS TO SAVE
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 16 that will ask for directory
information of the file to save or load.
Pressing the OK button with a valid numerical entry will begin
data collection. The numerical values change 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 passed to
the column name of each respective data file. Changing the field
named "Channel Name" in Figure 3 on page 3 will change the
name of the column data.

Running the Software with the ISL28023
Demo Board
All the controls and features discussed in the ISL28023 generic
board software are available to the user in the Demo software.
Connect and power the Demo board to the dongle board as
shown in Figure 18. Either use a power supply or a battery pack
to supply power to the Demo board. The Demo board can accept
voltages from 4.5V to 36V.
The ISL28023 Demo board connects the ISL28023 to a buck
regulator (ISL85415) and some resistive loads.
The board is properly powered by the battery pack with the most
negative voltage connected to the left of the VIN connector at the
top of the ISL28023 Demo board. This is illustrated in Figure 18.
Once properly powered, launch the ISL28023 software. The
same software used to control the ISL28023 generic board.
Press the "Connect To Device" button. The software will scan all
allowable slave addresses and determine the type of board
connected to the dongle. If the demo board is successfully
connected to the dongle, the window in Figure 19 appears.
The current going into the regulator is monitored by the Vshunt
inputs (Vinp, Vinm) and a shunt resistor of 0.02Ω(R20). The
VauxShunt inputs (Aux_P, Aux_N) are connected across a 0.02Ω
shunt resistor (R12). The VauxShunt channel measures the
current going to the load. The Vaux input measures the regulated
voltage at the load. The Vbus input measures the voltage applied
at VIN terminator. 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 ISL85415. The Vbus, Vshunt, Current, Power, Vaux channels
will turn on if they are not currently active.
The screen is the same as the ISL28023 generic evaluation
software plus the controls for the demo board. The Demo
Controls are illustrated as the ISL85415 group box in Figure 19.

Setting the Regulated Output Voltage
Enabling Efficiency Readings
Press the "Set Reg V" will launch the margin DAC window. The
margin DAC is connected to R15 or the Rg resistor of the
ISL85415 feedback. Equation 1 determines the regulated output
voltage.
By measuring the power going into the ISL85415 regulator and
calculating the power going to the load, the efficiency can be
calculated as shown in Equation 2, the efficiency equation used
in the ISL28023 Demo Software.

Where the reference voltage for the ISL85415 is 0.6V. The value
of R16 is the 120kΩ. The value of R15 is 20.5kΩ. The ISL85415 is
in a gain of 5.8537. The DAC_OUT is the voltage sourced from the
margin DAC. The output voltage will only work properly if the
output buffer and the DAC are enabled.
Setting the Switching Frequency
Press the "Set Freq" button to adjust the ISL23345, digitally
controlled potentiometer, which connects to the frequency select,
FS, pin of the ISL85415. The switching frequency of the regulator
will be altered causing the efficiency rating of the system to
change.
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.
(EQ. 2)
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.
Note: The power supply that is connected to the demo board
should be able to source 1A of current. If the sourcing capabilities
of the power supply are less than 1A, the regulate buck voltage
may oscillate or become unstable under certain load conditions.
Remember: The current of the primary channel of the ISL28023
only measures the current delivered to the ISL85415 buck
regulator. The VIN connector sources current to both the
ISL85415 and the 3.3V regulator that is part of the ISL28023.
The regulator draws approximately 1mA.
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.
