Power Good (PG)

The TPS6215xA-Q1 has a built in power good (PG) function to indicate whether the output voltage has reached its appropriate level or not. The PG signal can be used for startup sequencing of multiple rails. The PG pin is an open-drain output that requires a pull-up resistor (to any voltage below 7V). It can sink 2mA of current and maintain its specified logic low level. TPS6215xA-Q1 features PG=Low when the device is turned off due to EN, UVLO or thermal shutdown and can be used to actively discharge Vout (see Figure 42). VIN must remain present for the PG pin to stay Low. If unused, the PG pin may be left floating.
