UCD9090: Shared Control Signals RESET and PMBUS_CNTRL

Part Number: UCD9090

Hello Team,

Can you help me confirm a couple of questions about implementing the UCD9090 with shared traces.

The design in question would like to use the same Reset and PMBUS_CNTRL signals for two different UCD9090 devices.

  1. My assumption is that the PMBUS_CNTRL signal would not see any issues.
  2. For the reset, outside of system consideration of not being able to control these independently, is there any concern with using the same signal for both UCD devices?
    1. Any schematic recommendations for this implementation (ie is the 10k pullup on the rail still sufficient, and a 1000-pf capacitor from RESET to GND on both pins?)

Thank You,

Jacob Butler
