Part Number: AM3352
Other Parts Discussed in Thread: TPS65910

Hello. experts.

I took a look at Two am335x board : EVM board and SK board.

I found connecting is different, which is connecting from am335x C6(PMIC_POWER_EN) to TPS65910 P1(PWRHOLD).

The EVM board is connected, but SK board is not.

I don't know the reason that the two board is different in the pin connecting.

I am confused about what choice should be included in my design..

Thanks! Dears.

Hello GukHyun Lee,

Could you please share the links to the EVM and the SK boards.

The EVM is typically can be used as reference.

Hello, Sreenivasa

I attached two schematic files which are from TI link

The details are :

In SK Board, C6 is NC.

But in EVM Board, the C6 is connected from PMIC.

Regards, Lee.

Hello GukHyun Lee,

This connection is another way to control the PMIC. You could leave it open.

If routing permits, you can place a 0R and route the signal.
