5 TPS65313-EVM Power-Up and Power-Down Procedure
The EVM is preconfigured with the default jumper settings listed in Table 2 . Follow these steps to power
up the device:
Step 1. Connect the input supply voltage between the VBAT and PGND connectors to supply the
TPS65313-Q1 device.
Step 2. Press the S2 switch to apply a wake-up pulse which starts the device power up.
Step 3. It is possible to power up the device using the WAKE button on the GUI, when the J20
jumper is connected between pins 2 and 3, and the EVM is connected to the computer.
Before activating the
WAKE button on the GUI, click the Re-Initialize USB2ANY button on the
GUI to establish communication between the EVM and the GUI. For more information
regarding GUI functionality, see
Section 6 .
The TPS65313-EVM does not require any special power-down sequence. The EVM can be powered
down by turning off the VBAT supply or clicking the
CLR_WAKE_LATCH button on the GUI.
6 TPS65313 GUI
The TPS65313 GUI provides many features to help evaluate the TPS65313-Q1 device. The GUI has
three pages, or sections which are described as follows:
Device Controls page — This page, which is part of the High Level Configuration page, provides options
such as synchronizing the GUI with the EVM, wake-up control, watchdog configuration, MCU error
signal monitor (ESM), state transition control, NRES and ENDRV monitor, cyclical redundancy
check (CRC) enable, SPI status bit indicator, and device state indicator.
Register Map page — This page contains all the SPI registers and provides options to read or write the
TPS65313-Q1 device registers.
EEPROM Programming page — The TPS65313-Q1 device has many factory programmable device
options with unique orderable part numbers. By default, the TPS65313-EVM has a device with the
O31310QRWGRQ1 orderable part number. If users want to evaluate different device options (or
orderable part numbers), the EEPROM configuration can be updated using this page, which is part
of the
High Level Configuration page.
