Other Parts Discussed in Thread: UCD9090A
Hi Team,
Good afternoon, my customer is using the UCD9090-Q1 in their design and has a question:
- We initially planned to use the Reset pin on the chip to enable/disable the chip and kick off sequencing. However, it seems like we should instead be using the PMBus_CNTRL pin? The Datasheet on the UCD9090A has a section that explicitly makes note of this but the UCD9090-Q1 (which was the datasheet we were initially referencing) doesn’t seem to, though there are timing diagrams that seem to indicate the use of the CNTRL pin. Can you provide some detail on the how TI intended the CNTRL and RESET pins to be used?
Thank you!
Regards,
~John
