Powering up the Device
To turn on the device, perform the following steps:
1. Turn off the supply voltage, unplug the USB, and close the GUI.
2. While the power supply is disabled, connect it to the EVM through the J20 connector.
3. Plug the USB cable to the EVM and the computer. The MSP430 LED should blink a few times and
then stay on.
4. Set the power supply to a voltage between 3.135 V and 5.25 V. Turn on the supply voltage. The
LDORTC LED should light up.
5. Launch the GUI on the computer. All sequenced rails will power up to the predefined voltage.
6. Under the
DUT_Control
tab, send a logic high signal to the RESET_IN pin by checking the box next to
RESET_IN and clicking
Write Static
. The RESET_OUT LED should light up, and the PMIC is now
enabled.
