TPS54341: TPS54341

Part Number: TPS54341

Dear Support,

There is a confusion on the PWRGD of the TPS54341DPR design. Kindly know the technical usage of PWRGD signal in the particular design.

TI designs recommend to keep reference 5V on the PWRGD Pin with 1K pull up. 

If i need to connect 5VDC to the PWRGD pin, Do i need to short output 5V with PWRGD line ? Please clarify me the same.

Thanks,
Rahul

  • If you do not need the power good function for your system, then the PWRGD pin can be left open, no connection.

    If you need the power good function for your system, then a resistor should be connected from PWRGD to a 5V, or lower supply.

    Do not connect the PWRGD pin directly to a 5V supply.

    See attached drawing.
