The INA260EVM-PDK, which consists of the INA260EVM and SM-USB-DIG controller board, is a platform for evaluating the features and performance of the INA260 under various signal and supply conditions. This document gives a general overview of the INA260EVM-PDK, and describes the features and functions to be considered when using it.
Texas Instruments Product Information Center nearest you if any component is missing. NOTE: This EVM kit requires the INA260EVM GUI software, which is available for download through INA260 Tools & Software folder. Downloading the latest version of the GUI software is recommended.
• USB-powered; no external power supply is required • Support for full ±15-A input current range and 36-V common-mode voltage range of the INA260 • EVM includes placeholders for transient voltage suppression (TVS) devices to protect the INA260 inputs from excessively high common-mode voltages •...
EVM input terminals. The computer runs the GUI software through which the user can enable power to the INA260 and communicate with the device. User commands are sent through the computer's USB port to the SM-USB-DIG board that translates these commands into I C format, before sending them to the EVM.
C, SPI, and other serial digital I/O patterns. This EVM uses the I C interface of the TUSB3210 to control the INA260. Power supply for the SM-USB-DIG is derived from the USB interface. The SM-USB-DIG includes an onboard low dropout (LDO) regulator that uses the 5-V USB supply from the computer to generate a 3.3-V supply, which is then used to power all the active circuitry on board.
5V and 3.3V. The EVM supply voltage is user-selectable through the GUI. The 1µF ceramic capacitor, C2, placed in close proximity to the INA260 (U1) supply pin provides adequate decoupling to V for power supply rejection at higher frequencies.

The V input of the INA260 is accessible through pin 2 of header J1. Pins 1 and 3 of J1 are connected to IN+ and IN–, respectively. Note that the V input is independent of the current input (that is, the V input can be applied with or without a load), and the INA260 provides an accurate voltage reading.
C modes are supported. The outputs of the INA260 include SDA and ALERT, both of which are routed to J4 and are readable from the GUI. The GUI includes support for both over- and underlimit as well as conversion ready indicator modes of the ALERT pin.

INA260EVM-PDK Setup www.ti.com Make sure the hardware is not connected to the computer. Download the INA260EVM GUI from the INA260 Tools & Software folder. Extract the contents of the downloaded .zip file and run Setup_INA260EVM.exe. Follow the on-screen instructions provided in...
INA260EVM-PDK Setup www.ti.com INA260EVM Jumper Settings Figure 8 shows the default jumper configuration for the INA260EVM and Table 5 explain the purpose of each jumper. Ensure that the jumpers are installed in the correct positions, based on the required test conditions.
Table 5. INA260EVM Test Board Jumper Functions Jumper Default Purpose This jumper selects whether the V pin on the INA260 is connected to the IN+ or IN– pin; see Section 2.2.2 for details. This jumper sets the A0 character of the 2-character I C device address;...
INA260EVM-PDK Setup www.ti.com Next, with the output disabled, connect the input current source to the EVM via T1 and T2, as shown in Figure NOTE: The lug connectors can accommodate wire sizes up to #6-AWG. Also be sure to connect the low-side terminal of the input current source to EVM ground (GND) using one of the test points.
INA260EVM-PDK Setup www.ti.com System Power-Up Launch the INA260EVM GUI software. By default the Power button on the GUI is enabled so the POWER LED on the EVM immediately lights up, indicating that the EVM PCB is receiving power, as shown in Figure To input current...
Figure Figure 12. V Selection With the INA260 powered on, the analog input sources can now be enabled. Section 4 discusses the GUI configuration and data collection using this setup. INA260EVM GUI Software The INA260EVM GUI is a collection of software tools that make it easy for the user to explore the key behaviors of the INA260.
INA260EVM GUI Software www.ti.com Configuration Tool The Configuration tool allows the user to modify the operating conditions of the INA260 as required. User- specified settings are translated to I C frames and written to the appropriate device registers whenever the user clicks the Write All Reg button.
Therefore, step 1 involves selecting the correct A0 and A1 values that represent the slave address of the INA260 installed on the EVM. In other words, the states of A0 and A1 in the GUI must match the jumper settings chosen for J2 and J3 on the EVM. The equivalent hexadecimal value of the slave address is...
INA260EVM GUI Software www.ti.com The Averaging Mode menu allows the user to select a desired number of samples for the INA260 averaging feature. This step configures the INA260 to compute and store the average value of the specified number of samples in the output register. The default value is 1.
18. The data displayed includes the states of the Alert and Conversion Ready flags. Results are updated every time the output registers of the INA260 are read by clicking the Read All Reg button. Alternatively, data can be read continuously by enabling the Continuously Poll Data button on the Graph tool page.
20) allows the user to monitor and even change the contents of the internal user-accessible registers of the INA260 on a bit-by-bit basis. Bit names for the selected register are displayed on the lower panel of the page, but the user is advised to consult the INA260 datasheet detailed bit definitions that may be necessary when modifying the contents of the input registers.
