3.5 INA231EVM Default Jumper Settings

Figure 8 shows the default jumper configuration for the INA231EVM. In general, the jumper settings of the

SM-USB-DIG Platform do not need to be changed. You may want to change some of the jumpers on the

INA231EVM board to match your specific configuration. For example, you may wish to set a specific I

address by configuring J3-J6.

Figure 8. INA231EVM Default Jumper Settings

Typically, jumper 2 on the INA231EVM is always set to the INT position. When set to the INT position, the

SM-USB-DIG Platform provides the supply for the INA231. When this jumper is set to the EXT position, an

external supply voltage can be connected to terminal strip T2 to provide the supply for the INA231.

Jumpers 3 through 6 control the I

C address pins for the INA231. These jumpers can set the address for

A0 and A1 to either supply, ground, SCL, or SDA. Make sure to only connect one jumper at a time for

each address control. Failure to properly connect jumpers can cause shorts or interruptions in the

communication lines. For more information on the INA231 addressing, refer to the INA231 product data

sheet.

Table 4 summarizes the function of the INA231 Test Board jumpers. For most applications, all jumpers

should be left in the respective default configurations.

Jumper Default Purpose

J2 INT This jumper selects whether the V

pin on the INA231 is connected to the V

DUT

signal generated from the SM-

USB-DIG Platform or whether the digital supply pin is connected to terminal T2, allowing for an external

supply to power the device. The default INT position connects the V

pin to the V

DUT

control signal.

J3/J4 GND This jumper selects the I

C A0 address selection for A0.

J5/J6 GND This jumper selects the I

C A1 address selection for A1.
