Hi,

 

For power sequence of T2080, referred to "3.2 Power sequencing" of datasheet (pg: 48). Please suggest on the following:

 

  • Power sequence is not required apart from USB power, But for "USB_SVDD supply must ramp before or after the USB_HVDD and USB_OVDD supplies have ramped". Please confirm is it before or after
  • PORESET_B signal should be asserted after all power supplies are settled. Please confirm. As per 3.7 Reset initialization section "PORESET_B must be driven asserted before the core and platform power supplies are powered up."

 

Regards,

Mani
