title: UCD90320 power sequencer

description: |
  The UCD90320 is a 32-rail PMBus/I2C addressable power-supply sequencer and
  monitor. The 24 integrated ADC channels (AMONx) monitor the power supply
  voltage, current, and temperature. Of the 84 GPIO pins, 8 can be used as
  digital monitors (DMONx), 32 to enable the power supply (ENx), 24 for
  margining (MARx), 16 for logical GPO, and 32 GPIs for cascading, and system
  function.
