1.1 INTRODUCTION

The ADM00805 Evaluation Board for PAC1934 provides a flexible platform for evalu­ating PAC1934 and demonstrating the features of the PAC1934. A PAC1934 device in
a wafer level chip scale package (WLCSP) is mounted to the board.

The ADM00805 has a USB connector to connect to a computer for device communi­cation. The PAC1934 device may be powered directly by V
or by an external connection for V

ing the V
or a Linux system. See Section 4.9 “Direct External I2C Connection” for important
details if using direct I

The shorting shunts and the switch on the board facilitate either simple demonstration
of the device functions using on-board current sources or detailed evaluation of
function and performance with external sources, including prototyping the system.

1.2 PAC1934 DEVICE FEATURES

The PAC1934 is a four-channel DC power/energy monitor with accumulator. There is
a16-bit ADC for monitoring power rail voltages connected by a multiplexer to the posi­tive (+) input pin of each channel, producing results named V
16-bit ADC for measuring the voltage across a current sense resistor. This ADC is con­nected by a differential multiplexer to the +input and –input pins for each channel, pro­ducing results called V
sequential fashion to scan all four channels up to 1024 samples per second (sps).

The device also computes V
these power results in an Accumulator. The device registers also hold eight times aver­aged V
surements. All the results are stored in registers. The values in the Results Registers
only change when a REFRESH or a REFRESH_V command is sent. Software applica­tions are available for plotting, displaying and logging data. These applications also
calculate energy based on the accumulated power and accumulation time.

C address; some parts have a serial number that is displayed.

When clicked, the Settings button (3) displays a drop-down menu with two options: Set
Constants and Slow Register, as shown in Figure 3-3.

Note that you need to stop the acquisition process in order to have access to the Slow
Register. It is recommended that the acquisition process is stopped before changing
the values in the Set Constants Menu. Any changes to these values do not take effect
until the start of the acquisition.

FIGURE 3-3: SETTINGS DROP-DOWN MENU

The Set Constants option opens the Sense Resistor Values dialog box when clicked,
displayed in Figure 3-4. The default values shown are the sense resistor values in
DEMO mode. Enter a new value in ohms if the SYSTEM/SHUNT mode is used or if a
different value of sense resistor is used (see Section 3.3 “PAC Settings section”).

FIGURE 3-4: SENSE RESISTOR VALUES DIALOG BOX

Selecting the Slow Register option opens the Refresh Commands dialog box, displayed in

Figure 3-5, which allows the user to select which type of refresh commands, if any, occur

on the rising and falling edge of the SLOW pin transitions. Select the desired options and
the GUI programs the Slow Register (0x20) in the PAC1934 appropriately (see the

DS50002673A-page 20  2017 Microchip Technology Inc.

Software GUI Description

PAC1934 Data Sheet).This register is important if the SLOW pin is being used, the user will
be able to capture the data for very accurate energy calculation when switching from a pro­grammed sample rate to the eight samples/second rate under control of the SLOW pin. If
the SLOW pin is not being used, these settings can be ignored.

FIGURE 3-5: REFRESH COMMANDS DIALOG BOX

The Start Acquisition button, displayed in Figure 3-1 (2), toggles into Stop Acquisi-
tion when clicked. When the button is clicked, a REFRESH command is sent to the

PAC1934 and it starts collecting conversion data in the accumulator. The GUI starts
sending REFRESH_V commands to the PAC1934 and reading results data from all of
the results registers for data plotting (and logging, if selected).

When clicked, the Refresh button, displayed in Figure 3-1 (4), sends a command to the
PAC1934, updating the control registers and loading all the results from the ADCs and
the accumulator into the readable registers. The refresh command also resets the
accumulators and the accumulator count.

The Log to File button, displayed in Figure 3-1 (5), toggles when clicked to stop the
logging to file process and turns data logging on and off. In order to log the data, the
user must be acquiring. The data file is a CSV file created in the directory where the
GUI has been installed. There is a link next to this button to open the last log. Stop
acquiring data before opening the log file. When the Open Last Log button is clicked,
the most recent data log is opened. It can be noticed that all of the results data is cap­tured, and each column has a header identifying the data. Figure 3-6 shows one corner
of a log file.

Clicking the value for the Rate (Samples/s) option (1) opens the drop-down menu with
the available programmable sample rates for the PAC1934, shown in Figure 3-9.

Sleep mode and One Shot mode are two of the options that can be selected. In One
Shot mode, a new round of results are collected when a refresh command is sent with
the Refresh button right above the Sample Rate window.

Software GUI Description

FIGURE 3-9: SAMPLE RATE WINDOW - DROP-DOWN MENU

As seen in Figure 3-8, different values can also be entered for Refresh Period (2) and
Time to Show (3). Refresh Period determines how often the GUI reads the results from
the PAC1934. This is limited to 50 ms maximum by the ADM00805 Evaluation Board
hardware, not the PAC1934. The GUI performs the reading by sending a REFESH_V
command to the PAC1934 and then reads all of the results registers.

Time to Show determines the time span shown on the X axis for the plots. After chang­ing the Refresh Period of Time to show values, click the Set button to ensure that the
new values take effect. When new values are typed in, they are displayed in red. When
the Set button is clicked, the new values change to black.

The two radio buttons (4) at the bottom of the window control the format for the dis­played data for both the large Raw Data screen and for the log file. The options show
results in one of two ways:

• Calculated Values, which takes the Sense Resistor and full scale range values

into account for calculating current, voltage and power;

•

Register Values

, which shows the actual values in the registers, converted to decimal.

3.5 RAW DATA DISPLAY

Figure 3-1 shows the Raw Data window (6), which displays the raw data for all results

from all of the four channels. As described in Section 3.4 “Sample Rate and display

controls”, calculated values and the register values can be read here. Count is dis-

played for all four channels, but there is only one Count Value register so it is always
the same for each channel. Energy calculations are also displayed and take the sample
rate, the elapsed time between refresh commands, the sense resistor value, and the
full scale for voltage and current into account. See the PAC1934 Data Sheet for more
information about Power and Energy calculations.

3.6 PLOT WINDOWS

There are four individual plots in the plot window. The plot window may be configured
for single plots or multiple plots.

3.6.1 Single Plot option

For the Single Plot option, each plot may be configured to show data from any channel
with the channel selection window and drop-down menu on the left side above the plot.
Each window may be configured to show any of the results from the selected channel
with the results selection drop-down menu. Channel selection and results selection are
independent for each window. This is illustrated in Figure 3-10 and Figure 3-11.

Note that when selecting values from the drop-down menus, it works best to move the
cursor with the mouse and click the desired value, instead of using the scroll button on
the mouse.

For Multiple Plots option, the same results register from all four channels are always
plotted together in each of the four windows. The drop-down menu is used to select
which results are plotted in each window, as shown in Figure 3-13. An example of mul­tiple plots is displayed in Figure 3-14.

4.1 DEFAULT CONNECTIONS, DEMO MODE AND SYSTEM MODE

The PAC1934 is placed at the center of the board, in a wafer level chip scale package
(WLCSP), U1. It is surrounded by probe points with the pin names labeled. There is a
provision for an input filter for each pair on input pins, but these are not populated. The
other hardware on the board is described below.

In Figure 4-1, the USB connector is at the top. The yellow rectangles show the default

is also a yellow box around SW1. SW1 must be set to the ON position for USB
communication to work properly. In this default configuration the inputs of the four chan-

nels are connected across 1Ω sense resistors R5-R8. This is called the DEMO mode
configuration. These connections are made by the first column of jumpers on the left
side of the board, J6-J13. Each jumper has a shorting shunt connected to the DEMO
side of the jumper, near the resistor string R5-R8. These resistors are all in series and
connected to the on-board current source that flows through the resistors and then
through the shunt on J5 (near the top of the board) to V
removed to disable the on-board current source and see the noise performance of the
device with zero input. This current source generates a 0.5 Hz current square wave.
The amplitude is approximately 12.5 mA (J28 open) or 25 mA (J28 shorted, default
position). J28 is near the bottom of the board.

to the left (shunt position). In this configuration, connect V
(top) of the screw terminal connectors J1-J4 and connect the loads to terminal 3 (bot­tom) of these connectors. The center terminal of each connector is connected to
ground for a convenient return connection for the load. Each PAC1934 channel now
has an on-board current sense resistor of 4 mΩ connected between the positive (+)
input and negative (-) input pins, which gives 25A for the full scale current (V
is fixed at 100 mV).

For options that use a different value for R
menu in the GUI to enter the correct sense resistor values so that I
can be properly calculated (see Section 3.2 “Top Menu”).

The 4 mΩ resistors (R1-R4) can be unsoldered and replaced with a different value at
the discretion of the user. The 4 mΩ resistors have very wide metal connecting each
end to terminals 1 and 3 of the connector block, and it is challenging to remove them
cleanly. If they are removed, they will reveal a layout that facilitates soldering this wide
metal connection to each end of the new sense resistor and a kelvin connection for
each end that goes to the inputs of the PAC1934. Both the wide metal to the connector
block and the kelvin connection need to be soldered to the new sense resistor.

In the lower right corner are shorted jumpers J23 and J25 to connect the SLOW pin and
the ADDRSELECT pin to ground. Grounding the SLOW pin causes the PAC1934 to
function at the sample rate programmed by the GUI (default is 1024 samples per sec­ond). Removing the shunt on J23 allows the SLOW pin to be pulled high, overriding the
programmed sample rate and setting the sampling rate to eight samples/second. The
ADDRSELECT pin sets the SMBus/I

shunt sets the address to 22h. Other addresses can be selected by removing the shunt
and changing the value of R22 (see the PAC1934 Data Sheet for values). Nearby is
J24 for connecting the PWRDWN to ground if desired.

In DEMO mode, all four channels measure the same I

signal for Channel 1 is +5V USB. The V

other. Also, the +5V USB is not a low impedance power supply (it is generated from the
USB connection on the PC), so there is a small square wave on each V

Please note that the GUI is not capable of capturing data points as fast as the PAC1934
is capable of producing them. For this reason, the fastest rate that data can be captured
and plotted is approximately one point per 250 samples when sampling at 1024 sam­ples/second. Therefore, the true period variation of the un-averaged measurements

on J25 changes the address to 22h. Replacing R22 allows selection of other addresses
(see the PAC1934 Data Sheet).

The shunt on J23 pulls the SLOW pin to ground, so the device is operating at the pro­grammed sample rate. Removing this shunt selects an 8 Hz sample rate for low power
operation. The PAC1934 has a unique feature in that the status of this pin is tracked in
a register bit. This allows the GUI to change the displayed sample rate to 8 Hz when
the SLOW pin goes high. This is useful in real applications as well, when the user goes
to a SLOW sample rate and wants to capture the energy usage before and after the
SLOW pin transition. Requirements like this can also benefit from the features
described for the SLOW register settings, where the device can automatically be
refreshed by a SLOW pin transition.
