Miscellaneous Components
9.4.1
Power on Push Button
A footprint for a normally open, momentary push-button is provided at the PWRON terminal to allow a momentary
low state by pressing the push button. R43 allows isolation of the PWRON terminal from the MCU GPIO controlling
this pin.

PMIC LED Indicators
LED indicators are provided to notify the PMIC status to the user. Figure 22 shows the PMIC status LEDs D2 and
D4, and a Reserved LED indicator D3, that allows for an external rework connection to the transistor gate if any
given signal debug is required.
