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.
