Monitoring the Device Current

The TUSB1002 EVM includes the option of monitoring the current draw of the device. In order to enable
this feature, the following steps must be taken:

1. Un-install the shunt located at JMP11 and remove R26.

2. Obtain a power supply with the ability to display its current draw (or connect a current meter in series

to the power supply).

3. Connect to 3.3 V of external power source to VCC_3.3V (J11-2) and GND of the external supply to a

convenient GND location on the EVM (J10-2).

4. Turn on your power supply and observe the measured current on your power supply display (or current

meter).
