Part Number: TPS3808


Kindly review the attached schematics designed using TPS3808G30DBVT.  Signal from Reset  pin of this IC is used for resetting processor and its PMIC. Manual reset signal is connected to processor and reset switch of the system.

Please review the design and kindly let me know your comments.

    Hi, 

    Just curious, is there a reason for the R348 and C356?  The time constant is 220ms which seems to be quite long.  To monitor your voltage rail, I would add a 0.1uF cap on the SENSE pin to clean up any noisy transients on the monitored voltage rail.  As for R348, I would place a 0ohm resistor just in case you needed to add some low-pass filtering for the SENSE pin.

    Other than that, the schematic looks great.
