5 Setup

The following steps are intended to help users power up and evaluate the EVM.

1. To use the TPS65864xEVM with a personal computer, the TPS865864xEVM software is required

along with the HPA172 USB-to-I2C Interface Board (USB-TO-GPIO) and a USB cable. Two power

supplies capable of supplying 6 V at 2 A are required.

2. To test the HPA752, the computer must have the TPS65864xEVM software program installed. Install

the program from the TPS65864xEVM software zip file. This software zip file is supplied by Texas

Instruments. If the program does not automatically install properly, follow the instructions in the

Readme file.

3. Connect the USB cable between the computer and the HPA172. Connect the Molex cable between the

HPA172 and the HPA752 EVM (J11).

4. Verify the shorting jumpers are installed as noted in the shorting jumper table. The EVM ships with the

default jumper settings.

5. Supply 1: Set the input supply voltage to 3.3 V before connecting to the EVM, and turn the supply off.

While in the off state, connect the power supply positive lead to J36 (EVM 3V). Connect the power

supply return lead to J39 (GND).

6. Input Supply 2: Set the input supply voltage to 5 V before connecting to the EVM, and turn the supply

off. While in the off state, connect the power supply positive lead to J5 (VIN). Connect the power

supply return lead to J6 (GND).

7. First, turn on Input Supply 1 (3.3 V). Next, turn on Input Supply 2 (5 V).

8. To wake the PMU, hold the pushbutton switch, S1, RESUME, for one seconds and release. While the

PMU is awake, holding switch S1 for one second puts the PMU back into the sleep state. Different

combinations of the LDOs and switching converters turn on by default as per table 3-3: TPS65864x

Integrated Power Supply Power-Up Defaults in the corresponding device data sheet. Note, final silicon

can be marked as TPS658643 or P658643.

9. Using the GUI, select the LDOs tab on the left side. Press Read to load the contents of the I2C
