power-good detector (TPS60211 and TPS60213)
The power-good output is an open-drain output that pulls low when the output is out of regulation. When the
output rises above 91% of its nominal voltage, the power-good output is released. When the device is
programmed into snooze mode (SNOOZE = LOW), the power-good detector is disabled and PG is high
impedance. In normal operation, an external pullup resistor must be connected between PG and OUT, or any
other voltage rail in the appropriate range. The pullup resistor should be in the 100-k
Ω to 1-MΩ range. If the PG
output is not used, it should remain unconnected.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
