2.2.1 SM-USB-DIG Platform Theory of Operation
Figure 4 shows a block diagram for the SM-USB-DIG platform. This platform is a general-purpose data
acquisition system that is used on several different Texas Instruments' evaluation modules. The details of
its operation are included in a separate document. The block diagram shown in Figure 4 is given as a brief
overview of the platform.
The primary control device of the SM-USB-DIG platform is the TUSB3210. The TUSB3210 is an 8052
microcontroller that has a built-in USB interface. The microcontroller receives information from the host
computer that it interprets into power, I2C, SPI, and other digital I/O patterns. During the digital I/O
transaction, the microcontroller reads the response of any device connected to the I/O interface. The
response from the device is sent back to the PC where it is interpreted by the host computer.
Figure 4. SM-USB-DIG Platform Block Diagram
3 INA3221EVM Hardware Overview
Setting up the INA3221EVM hardware involves connecting the two EVM PCBs together, applying power,
connecting the USB cable, and setting the jumpers. This section presents the details of this procedure.
3.1 Electrostatic Discharge Warning
CAUTION
Many of the components on the INA3221EVM are susceptible to damage by
electrostatic discharge (ESD). Customers are advised to observe proper ESD
handling precautions when unpacking and handling the EVM, including the use
of a grounded wrist strap at an approved ESD workstation.
3.2 Connecting the Hardware
To connect the INA3221EVM and SM-USB-DIG platform together, gently slide the male and female ends
of the 10-pin connectors together. Make sure that the two connectors are completely pushed together;
loose connections may cause intermittent operation.

3.4 Connecting the USB Cable to the SM-USB-DIG Platform
Figure 6 shows the typical response to connecting the SM-USB-DIG platform board to a PC USB port for
the first time. The connection between the SM-USB-DIG and PC USB port is shown in Figure 7. Typically,
the computer responds with a Found New Hardware, USB Device pop-up dialog. The pop-up window
typically changes to Found New Hardware, USB Human Interface Device. This pop-up indicates that the
device is ready to be used. The SM-USB-DIG platform uses the human interface device drivers that are
part of the Microsoft®Windows®operating system.
In some cases, the Windows Add Hardware Wizard may pop up. If this prompt appears, allow the system
device manager to install the human interface drivers by clicking Yes when requested to install drivers.

3.5 INA3221EVM Default Jumper Settings
Figure 8 shows the default jumper configuration for the INA3221EVM. Some of the jumpers on the
INA3221EVM board can be changed to match specific configuration requirements. For example, a specific
I2C address can be set by configuring jumpers J1 and J2.
Figure 8. INA3221EVM Default Jumper Settings
Jumper 3 on the INA3221EVM is typically set to the INT position. When set to the INT position, the
INA3221 supply voltage is generated and controlled by the SM-USB-DIG platform. When this jumper is set
to the EXT position, VS connects to terminal strip T2.
Jumpers J1 and J2 control the INA3221 I2C address pin. These jumpers can set the address (A0) pin
to either high, low, SCL, or SDA. Make sure to only connect one jumper at a time, never both.
Failure to properly connect jumpers can cause shorts or interruptions in the communication lines. For
more information on the INA3221 addressing, refer to the INA3221 product data sheet.

Table 4 summarizes the function of the INA3221 test board jumpers. For most applications, all jumpers
should be left in the respective default configurations.
Table 4. INA3221EVM Test Board Jumper Functions
Jumper Default Purpose
J1 GND These jumpers select the I2C A0 address selection. Four separate I2C addresses can
be selected, depending upon whether J1 is set high or low or whether J2 is set to SDA
J2 Open or SCL.
This jumper selects whether the INA3221 DVDD pin is connected to the VDUT signal
generated from the SM-USB-DIG platform or whether the digital supply pin is
J3 INT connected to terminal T2, allowing for an external supply to power the digital circuitry.
The default INT position connects the DVDD pin to the VDUT control signal.
3.6 INA3221EVM Features
This section describes some of the hardware features present on the INA3221EVM test board.
3.6.1 J3: I2C VSControl Setting
Jumper J3 selects what the INA3221 supply pin is connected to. If J3 is set to the INT position, the VS pin
is connected to the switchable VDUT signal generated from the SM-USB-DIG platform. This voltage can be
set to either 3.3 V or 5 V, depending on how it is configured in the software. While J3 is set in the INT
position, the VS Power button in the INA3221EVM software is able to control whether the VDUT supply
voltage is turned on or off. When J3 is set in the EXT position, an external supply connected to terminal
T2 can be used to provide the INA3221 supply voltage.
3.6.2 J1 and J2: I2C Address Hardware Setting (A0)
Jumpers J1 and J2 are used to set the hardware setting for the A0 I2C address pin on the INA3221. Using
J1, the A0 address can be set to either a logic '1' or a logic '0'. Using J2, the A0 address can be set to
either the SCL or SDA communication line. Make sure to only have either J1 or J2 connected individually;
failure to keep these lines separate can lead to board shorts and problems with the I2C communication
lines. See Section 5.2.1 on how to configure the INA3221EVM software to match the J1 and J2 hardware
setting.
3.6.3 External I2C Lines and Terminal Block T1
The INA3221EVM I2C communication lines are tied to two sources: the internal I2C communication lines
from the SM-USB-DIG and terminal block T1. If the user wants to add external signals separate from the
SM-USB-DIG, simply disconnect the SM-USB-DIG from the INA3221EVM board and hook up the
necessary SDA, SCL, and GND lines. Also, remember to apply an external DVDD to the lines compatible
with the I2C communication device being used.
NOTE: Failure to disconnect the SM-USB-DIG while using external I2C communication can cause
damage to the SM-USB-DIG or any connected external communication devices.
