1.1 INTRODUCTION

The ADM00805 Evaluation Board for PAC1934 provides a flexible platform for evalu- ating 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 communi- cation. The PAC1934 device may be powered directly by VBUS from the USB connector or by an external connection for VDD. I2C communication can be provided over USB using the on-board MCP2221 USB to I2C Bridge. There is also a header that facilitates direct I2C communication by connect- ing the VDD_IO, Ground, SDA and SCL to an external source such as a PC motherboard or a Linux system. See Section 4.9 “Direct External I2C Connection” for important details if using direct I2C connection. 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 posi- tive (+) input pin of each channel, producing results named V BUS. There is a second 16-bit ADC for measuring the voltage across a current sense resistor. This ADC is con- nected by a differential multiplexer to the +input and –input pins for each channel, pro- ducing results called VSENSE. Channel selection for the multiplexers is controlled in sequential fashion to scan all four channels up to 1024 samples per second (sps). The device also computes VPOWER by multiplying VBUS by VSENSE and accumulates these power results in an Accumulator. The device registers also hold eight times aver- aged V BUS and VSENSE results for very accurate low noise voltage and current mea- 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 applica- tions are available for plotting, displaying and logging data. These applications also calculate energy based on the accumulated power and accumulation time.

1.3 ADM00805 EVALUATION BOARD FOR PAC1934

1.3.1 Hardware Overview

The ADM00805 Evaluation Board has a PAC1934 device mounted on the board and enables direct control of all device pins and easy measurements of on-board or exter- nal voltages and currents. The I2C address is connected as 0x20 by default. Removing a shunt gives 0x22. Other addresses are possible by replacing R22 with a new value. Sampling rate is 1024 sps by default, due to the shorting shunt on the SLOW pin con- nector (J23) tying the SLOW pin to ground. Remove this shunt for the SLOW sampling rate of 8 sps.

PAC1934 Evaluation Board (ADM00805) User’s Guide DS50002673A-page 12  2017 Microchip Technology Inc. An on-board current source provides a 0.5 Hz square wave current signal for function- ality testing and demo purposes. There are also on-board current sense resistors, pro- visions for external sources and loads, and provisions for both USB control and direct I 2C connection. See Chapter 4. “Hardware Description” for more details.

1.3.2 Software and System Control Overview

The PAC193X Demo Application, described in detail in Chapter 2. “Installation and Operation”, provides USB control of the PAC193X with the ADM00805 Evaluation Board. The application provides an easy way to control all of the programmable registers and read all of the results for the PAC1934 device on the ADM00805 Evaluation Board. To use this software application with the ADM00805 Evaluation Board, download the soft- ware and launch the application.

3.2 TOP MENU

As seen in Figure 3-1, the Device window (1) shows the device on the board and its I2C 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 RESIST OR 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

 2017 Microchip Technology Inc. DS50002673A-page 21 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 pro- grammed 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 cap- tured, and each column has a header identifying the data. Figure 3-6 shows one corner of a log file.

3.3 PAC SETTINGS SECTION

Each input channel of the PAC1934 is internally set for unipolar/unidirectional voltage on VBUS and unidirectional currents on VSENSE by default. However, in the GUI, all four channels are configured for bidirectional currents by default. This bidirectional setting avoids clipping of negative values. For bidirectional currents the VSENSE results are in 16-bit two's complement representation. A drop-down menu allows reconfiguring each channel or turning it off as shown in Figure 3-7 for channel 4 (1). Using the GUI this way programs the appropriate register for the selected channel. FIGURE 3-7: PAC SETTINGS WINDOW

3.3.1 Alert Settings

The check boxes enable turning on the alert function and selecting which type of con- ditions can trigger the alert function: Conversion Complete or Accumulator Overflow. The alert status is also displayed underneath the check boxes, as shown in Figure 3-7 (2). The GUI is not fast enough to capture the conversion based ALERT, which lasts only 5 μS. The SLOW/ALERT pin must be monitored with a circuit fast enough to detect the 5 μS wide ALERT signal to use this function.

 2017 Microchip Technology Inc. DS50002673A-page 23

3.4 SAMPLE RATE AND DISPLAY CONTROLS

Figure 3-8 shows the Sample Rate window, located to the right of the Alert window. FIGURE 3-8: SAMPLE RATE WINDOW 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. 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 chang- ing 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 dis- played 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.

PAC1934 Evaluation Board (ADM00805) User’s Guide DS50002673A-page 24  2017 Microchip Technology Inc.

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.

3.6.2 Multiple Plots option

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 mul- tiple plots is displayed in Figure 3-14.

4.1 DEFAULT CONNECTIONS, DE MO 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. FIGURE 4-1: ADM00805 EVALUATION BOARD

4.2 DEFAULT CONNECTIONS, DEMO MODE AND SYSTEM MODE FOR

In Figure 4-1, the USB connector is at the top. The yellow rectangles show the default (as shipped) position of the shorting shunts that connect the different pin pairs. There 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-

PAC1934 Evaluation Board (ADM00805) User’s Guide DS50002673A-page 28  2017 Microchip Technology Inc. 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 DD. The shunt on J5 may be 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. All of the plots in Chapter 3. “Software GUI Description” are made in DEMO mode with the default connections.

4.3 V BUS AND VSENSE CONNECTIONS - USING EXTERNAL SOURCES FOR

To use external sources for VBUS with an external load, the shunts J6 - J13 are moved to the left (shunt position). In this configuration, connect VBUS sources to terminal 1 (top) of the screw terminal connectors J1-J4 and connect the loads to terminal 3 (bot- tom) 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 SENSE FSR is fixed at 100 mV). For options that use a different value for RSENSE than the default 1Ω, use the Settings menu in the GUI to enter the correct sense resistor values so that ISENSE and Power 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.

4.4 OTHER HARDWARE ON THE BOARD

The second columns of jumpers (J14-J17) are by default in the correct position for either DEMO mode or System (shunt) mode. Their function is to enable measurement of the current going into the V DD pin and the current going into the VDD_IO pin. This is described in Section 4.7 “PAC1934 current measurements using the PAC1934.” 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 sec- ond). 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 2C address to 20h when grounded. Removing the 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.

4.5 HARDWARE FOR I 2C/SMBUS COMMUNICATION OVER USB OR EXTERNAL

Directly above J22 is U2. This is an MCP2221 USB-2 to I2C bridge chip that translates the USB communications into I2C read/write commands to configure the PAC1934 and to capture status and results data. To the left of U2 is U3, a level shifter that matches the I2C signals from the MCP2221 to the VIO voltage that the user is using for the PAC1934 VDD_IO. On the far right side of the board, there is a switch SW1 and a con- nector J27. These are both used when connecting an external I2C connection directly to the board instead of using the USB connection. J27 allows the user to connect the external VIO, SCA, and SCL signals directly to the PAC1934. SW1 disables the USB bridge and level shifter and connects the pull-up resistors on SCA and SCL pins to the external V IO voltage.

4.6 SIGNAL DESCRIPT ION IN DEMO MODE

In DEMO mode, all four channels measure the same ISENSE. VSENSE matching is lim- ited by resistor matching. All four channels measure similar VBUS levels. The VSENSE signals are equal to the current source value multiplied by 1Ω (25/50 mV).The VBUS signal for Channel 1 is +5V USB. The VSENSE inputs for the other channels are sepa- rated from +5V USB by each sense resistor’s voltage drop so they are offset from each 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 BUS signal as the ISENSE current interacts with the output impedance of +5V USB. All of the plots in the GUI description above are made in the default DEMO mode configuration. 4.7 PAC1934 CURRENT MEASUREM ENTS USING THE PAC1934. The ADM00805 Evaluation Board can be used to measure the PAC1934 VDD and VIO currents. For both measurements below, the sense resistor values for Channel 1 (VIO) and/or Channel 4 (VDD) require changing to 10Ω for proper scaling of the ISENSE and power measurements. To measure the current in the VDD_IO pin, move the shunts on J14 and J15 to the VIO position (see Figure 4-1). This connects Channel 1's inputs across R24, which is con- nected between VDD_IO and VIO. R24 is a 10Ω sense resistor that can measure the cur- rent going into the VDD_IO pin on the PAC1934. This is a very low current, and allows the user to see the benefit of using VSENSE average for making very accurate VSENSE/ISENSE measurements for low currents. The VSENSE measurements have a periodic variation, repeating every four measure- ments. This periodic variation is due to a design feature that caused the average VSENSE/ISENSE measurement (and the accumulated power) to have nearly zero offset. Figure 4-2 displays VBUS (VDD_IO) and current into VDD_IO.

PAC1934 Evaluation Board (ADM00805) User’s Guide DS50002673A-page 30  2017 Microchip Technology Inc. FIGURE 4-2: MEASURING THE VOLTAGE AND CURRENT ON THE V IO PIN WITH CHANNEL 1 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 sam- ples/second. Therefore, the true period variation of the un-averaged measurements cannot be accurately seen with this GUI and appears more like noise. A similar option is available in DEMO mode for measuring the V DD current required by the PAC1934. The IDD current flows in R19 (10Ω). Move the shunts for J16 and J16 to the VDD position to connect Channel 4 inputs across R19, and the GUI may be used to display IDD as ISENSE on channel 4. In Figure 4-3 VDD is displayed as VBUS with chan- nel 4 and IDD is displayed as Current on Channel 4. FIGURE 4-3: MEASURING THE VOLTAGE AND CURRENT ON THE V DD PIN WITH CHANNEL 4

4.8 ADDITIONAL HARDWARE DETAILS

Directly above and below the PAC1934 are shorted jumpers labeled VIO (J22) and VDD (J29). These provide a place for removing the short and inserting a current meter if the user wishes to measure the current in the V DD_IO pin and/or the VDD pin.

 2017 Microchip Technology Inc. DS50002673A-page 31 J30 may be used to provide external power in place of the +5V USB power derived from VBUS if the USB is not connected. J30 is labeled 5V, but external voltages applied to the pin labeled 5V may be anywhere from 5.5V to 2.7V. This may be needed if the external I 2C signals are used with no USB connection J25 sets the I2C/SMBus address to 20h when the shunt is in place. Removing the shunt 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 pro- grammed 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.

4.9 DIRECT EXTERNAL I 2C CONNECTION

The ADM00805 can be used with direct I2C control from a PC running Windows®, Linux® or other digital controller. VDD_IO may need a different voltage for external I2C use than the default settings for USB control. This is easily implemented by moving SW1 from the ON/5V position used for USB control to the OFF/EXT position used for external I2C control. Connect the external SCA and SCL signals is then required, along with the power (VIO) and ground used for these I2C signals, to J27. Generally, the user will not be able to use the PAC193x Demo Application with direct I2C connection. For Windows® 10 systems, the user can embed sense resistors in series with the power rails to be monitored/measured, interface to the ADM00805 with direct I2C con- nections and use the Windows® 10 driver to interface the energy metering functions with the OS.
