[beagleboard] REGEN1 pin

[Chandan Kumar]

Hi Sir,

I am designing a PCB using AM5728 processor with TPS659037 PMIC ,i have 
kept Beagle board X15 schematics as reference .
I have a doubt on REGEN1 pin. The datasheet of TPS659037 says the REGEN1 
output is active high but it has been pulled up to 3.3V in the load switch 
(TPS22965DSG)side .Also the default output configuration(OTP) for REGEN1 
output is push-pull.

So please suggest me  how to design VDD_ON_3V3 line such that the 
TPS22965DSG should be ON so that i can configure PMIC for the required 
settings soon after i assemble the board.

Thanks,
Chandan

You must use the REGEN1 pin as done on the schematic to guarantee the power
sequencing. The design in the schematic works. If you want to create a new
design and try something else, then you are certainly welcome to do so.
