HS FAE Germany

Tool/software:

Hi,
do the VMON_1P8_SOC, VMON_3P3_SOC pins need a blocking capacity (eg. 100nF)? The HW design guide doesn't mentioned that:

Hello Holger,

Thank you for the query.

The recommendation is to connect the supply to be monitored without any cap. The cap could suppress the variations that may be seen on the supply only at the pin and may not reflect the actual supply being monitored.

We will clarify the notes in the next revision.
