...

The power consumption is about the same for USB/HID and I2C. The power consumption will vary with different sensor parameter configurations. The graph above is valid for a default sensor parameter configuration. By increasing the scanning range from default, the power consumption will increase.

Definition

The power consumption is calculated from the current consumption when supplying the sensor module with 5 V. 

...

According to the different working modes of the Touch Sensor Module, the current consumption value also changes between Active mode and Idle mode.
