UCD9090ARGZR is a 10-rail PMBus/I2C power sequencer and monitor for systems requiring controlled rail startup, shutdown, voltage supervision, fault handling, and margining.

Best for

  • Multi-rail power sequencing
  • PMBus-managed industrial and server power systems
  • Voltage monitoring and fault logging

Avoid if

  • A design needs monitor inputs above 2.5 V without external scaling
  • A simple fixed-sequence solution with no PMBus configuration is sufficient

Check before use

  • Verify all monitored rails are scaled within MON input limits.
  • Use appropriate pullups or pulldowns on enable signals for reset behavior.
  • Review PMBus address selection; address 126 enables JTAG mode and is not recommended for normal operation.
