2 Setup
This section describes the setup of EVM, including EVM hardware and GUI operation.
2.1 EVM Hardware Connections
The TI communication board should be connected to the IC EVM board via a 30-pin connector in the
shipment box. Connect them if they are not connected yet, as shown in
Figure 1 .

Designator Label
JP1 VDD_SEL Installed (default): When the USB is connected, the TI communication board supplies the 5-V VDD
rail.
Uninstalled : The 5-V rail must be supplied externally to the VIN test point.
JP2 CLK_SEL Installed (default): When USB is connected, the TI communication board supplies a clock signal to
the TPIC8101. The GUI can adjust the frequency.
Uninstalled : The clock must be supplied externally to the XCLK test point.
JP3 INT/H Installed (default): When the USB is connected, the TI communication board supplies the INT/H
square wave signal at the period specified in the GUI.
Uninstalled : The INT/H signal must be supplied externally to the INT/H jumper pin 2.
