Other Parts Discussed in Thread: TPD5S116

Hello.

My customer have some questions about TPD5S116.

Q1) Is there any sequence of power-on about VccA , 5V_SYS ？

Q2) In the figure 17. there is a 300mV voltage source between Port A output FET to GND.

For what purpose is the voltage source there?

Regards,

Naoki,

Q1) There is no start-up sequence necessary for TPD5S116.

Q2) The 300 mV source prevents the Level shifter from latching up when both Port A and Port B are being pulled down and then let go and pulled up.
