The Launchpad receives power from the 5V input on the USB connector. This 5V input serves as the input to the TPS65036x-Q1 PMIC (orderable part number: TPS65036604RAYQ1). The PMIC on the board generate all the voltage rails required for the Microcontroller. All power supply sequencing and voltage monitoring is handled by the PMIC. Refer to Section 1.3.1 for specific requirements on the 5V input to the Launchpad.
The F29H85x device and the PMIC on the Launchpad can be connected via I2C bus by populating R29 and R32. The I2C bus is used by the device to configure the PMIC and also, when enabled, to service the PMIC's watchdog. The I2C bus GPIOs are also connected to the I2C standard location on J5 by default.
PMIC watchdog is disabled by default. User can enable watchdog by removing R18. Similarly, ERRORSTS is not connected to PMIC by default. By populating R26 and R27, ERRORSTS is connected to GPIO which can be configured as PMIC ESM input.
