TLIN1029A-Q1: Power up time(tPWR)

Youhei Miyaoka

Part Number: TLIN1029A-Q1

Hello team,

I understand tPWR is time from power-up to RXD valid data output.

Does this power-up timing mean from at Vsup>0V or Vsup>4V(Vsup_min)?

Seeing from datasheet, there is no timing chart, can you share the timing chart?

Regards,

    Hi Youhei,

    Although the data sheet does not explicitly define the starting threshold, based on the device operation:

    • The receiver is not guaranteed to operate below the under voltage threshold.
    • Hence, tPWR should be referenced from when VSUP has risen above the valid operating / under voltage threshold, rather than from 0 V.

    I.e., the timer should effectively begin once the device has sufficient supply voltage to exit under voltage and begin initialization, thanks.

    Best Regards,

    Michael.
