FS45 power up/down squence confirmations

[Eason_L]

Hi,

I have some questiINons about FS45 power up/down squence, please help to confirm, thanks!

1. My VCORE and INTB power up at the same time, is it correct(a bit different from datasheet)? My VCORE is connected to VDDIO. INTB is pulled up to VDDIO.

2. Is my VCORE and RSTB working properly?

3. INTB and VCORE shoud power down at the same time, but INTB has a p rior slope(circled in pic), is it correct? After expanding INTB and VCORE wave forms, I found INTB is 260us late compare to VCORE, is it correct?
