SLVSCD6 – DECEMBER 2015

8.4.5 Power Good (PG)

The TPS62097 has a power good output. The PG pin goes high impedance once the output voltage is above

95% of the nominal voltage, and is driven low once the output voltage falls below typically 90% of the nominal

voltage. The PG pin is an open drain output and is specified to sink up to 1mA. The power good output requires

a pull-up resistor connected to any voltage rail less than 6V. The PG pin goes low when the device is disabled or

in thermal shutdown. When the devices are in UVLO, the PG pin is high impedance.

The PG signal can be used for sequencing of multiple rails by connecting it to the EN pin of other converters.

Leave the PG pin floating when not used.
