Hello.
I found the following topic:
AM1808 Power-on Sequence Timing
http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/t/108307.aspx
Mr.Paul said that it needs to be ramp up 1.2V to nominal level before starting to ramp up 1.8V.
However, there is no such description in the AM1808 datasheet, there is the ramp up order only in the datasheet.
The following is my understanding. Is it correct?
- It is necessary to ramp up in the order described in the datasheet.
- The power supplies need to be stable at nominal level before starting to ramp up next one.
Best regards,
Keigo Ishii
