Hello,

Regarding to VSIM* Start-up time(TSTR) on TXS4558, my customer is asking a question.

(Question)

･Which is start point of TSTR ?

Is it CSELsignal edge point? or VSEL* signal edge point?

Or is it from a point(ex.10%) to a point(ex.90%) during Vsim rising time?

If so, it depends on output current or capacity.

My understanding is correct?

Regards,

Hi Tao,

The start up time is for the Vsim1 or Vsim2 rise time from 10% to 90% across process/ temp variations with the stated test conditions of the current and output capacitor.

All other pins are in their respective default states to select the Vsim1/2 operation.
