Power-Good detector (TPS60131 and TPS60133)

The PG pin is an open-drain output that is pulled low when the output is out of regulation. When the output

voltage rises to about 90% of its nominal voltage, power-good output is released. PG is high impedance when

the device is disabled. An external pullup resistor must be connected between PG and OUT. The pullup resistor

should be in the 100 k

Ω to 1 MΩ range. If the power-good function is not used, the PG-pin 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.
