Hello expert,
My customer has some questions about the UCD90320 GPI and reset function.
- How to configure the GPIO as power good function? the trigger criteria is from the MON rise the certain level and the GPIO will go high to indicate this power rail is good/okay.
- Will the GPI interrupt and fault response valid in start-up period(power on sequence)? If no, that's what customer want. If yes, how to make sure the GPI or fault response will not stuck this sequence?
- Is the Pin selected function can only valid at the GPI as below pic1?
- Could GPI act as a reset function pin like when GPI go high -> power off sequence, go low -> power on sequence?
- Will the PMBUS_CRTL(pin E11) re-do the power sequence or not?
- When 32 powe rail/EN are set, is there any further way to collect AMON/GPIO power good signal from GPIO/EN3
Could you kindly help to check on above questions and provide the answer? Thanks!
Best regards,
Ann Lien
