I use the MMPF0100F9AZES to power the IMX6Q Plus.

From the BOM-28857_A2.xlsx, SH4 and SH5 is DNP. is it right?

I test the board, VDDCORE and VDDCORE_FB is disconnect when SH4 is DNP.

Thank you!

Hi,

That is correct, when SH4 is open (DNP), VDDCORE and VDDCORE_FB are disconnected.

SH5 is used to disconnect SW2LX output of the PMIC from the VDDCORE rail, in other words, when SW2 output is not used.

 

In the BOM, all the Solder Shorts (SHx) are marked as DNP because they are not components, these are layout elements only, so, they are not meant to be placed or not. These are layout traces that can be cut if needed.

Regards,

Jose
