7.3.6 Power Good (PG)

The TPSM82480 has a built in power good function. The PG pin goes High, when the output voltage has reached its nominal value. Otherwise, including when disabled, in UVLO or thermal shutdown, PG is Low. The PG pin is an open drain output that requires a pull-up resistor and can sink typically 2mA. If not used, the PG pin can be left floating or grounded.
