TUSB1210-Q1 Power Sequencing

Other Parts Discussed in Thread: TUSB1210-Q1

Hi,

My customer would like to confirm the power sequencing of TUSB1210-Q1.

Is there any specification for the power supply start-up/down timing?

Is it following only?

Though I found following thread on the E2E, I post this thread because there is no clear answer on the thread.

    Hello Kuramochi,

    Recommended operation is for Vbat to be present before VDDIO. If VDDIO is present but VBAT isnot may cause some internal leakeage. However it is unlikely this leakage will be significant, and since it is transitory only, it should be acceptable.

    Regards,
