TPS62148: PGOOD - Trigger Conditions Summary

Part Number: TPS62148

Hi Team,
Normally I would take the time to review the DS to help answer this Q, but I am currently resource-strained.

I need to know a summary of all the ways PGOOD works.

1) How the Output Voltage and PGOOD (I am 100% sure this is in the DS)
2) How the EN pin voltage and PGOOD work

Any other ways PGOOD could be triggered High/Low
(Overcurrent, etc)


  • Hi Darren,

    The PG pin is an open-drain output that requires a pull-up resistor to any voltage up to a voltage level of the input voltage at VIN. It can sink 2 mA of current and maintain
    its specified logic low level.

    When EN=HI and PG > VTH_PG then PG is high. When EN=HI and PG < VTH_PG then PG is low. PG is low when the device is turned off due to EN, UVLO or thermal shutdown. VIN must remain present (>0.7V) for the PG pin to stay low.

    Here is the table summary:

    VTH_PG thresholds are mention in EC table:

    Hope this helps.
