AM6421: Power Down Sequence

Kuramochi Tadahiko
Guru 28715 points
Part Number: AM6421

Hi,

There is the following figure on the datasheet.

Inside of the red rectangle is drawn diagonal lines.

On the other hand, inside of the blue rectangle is not drawn diagonal lines.

What is the difference between having/not having these lines?

Best Regards

Kuramochi

    Hi Kuramochi,

    The diagonal or hash marks represent multiple power signals. The hatch marks within a shaded region is used to represent multiple power rails just in case all power rails represented by a waveform are not powered from the same source. For example, there may be a reason to power some 1.8V power rails form one source while other 1.8V rails are powered from another source.

    Regards,
