8.2.2.7 RPG - PG Pullup Resistor

The PG pin is an open drain output that is used as a monitoring pin. If needed, a 100kΩ can be used to pull up to a suitable voltage supply. See also Section 6.3 for a range of recommended PG pin pullup voltages. Other considerations, such as power consumption, can increase any of the values listed above.
