TPS2372: tps2372

Part Number: TPS2372

Hi All,

I just want to be sure when the PG line becomes high impedance if IRSHDL_EN is open. Will it do when the Cbulk capacitor is fully charged ? or when the inrush delay period has exceed 81.5ms? or whichever come first or later?.

Thanks in advance,

Daniel.

    Hi Daniel,

    If inrush delay enable pin is open, then it is both when cbulk is fully charged AND the inrush delay period is met. Please see below what is on page 15 of the TPS2372 datasheet.

    "The PG output becomes high impedance to signal the downstream load that the bulk capacitance is fully charged and the inrush
    period has been completed."

    Please let us know if this helps. Thanks!
