TUSB1310A: Internal latched strapping pin states

Kuramochi Tadahiko

Part Number: TUSB1310A

Hi,

I have a question about Figure 5-1. Power-Up Sequence of the datasheet.

I'm understanding that the strapping pin is latched when all power supplies complete to rise up regardless of power rails sequence .

Is it correct?

Best Regards,

Hi Gerado-san,

Thank you for your answer.

I have an additional question.

When only 1.1V power supply restart(rises up after fall down), is strapping pin states latched?
Or must all power supply restart to be latched strapping pin states?

Best Regards,
Kuramochi

Hello Kuramochi,

All power supplies must be restarted in order the strapping pins could be latched.
