0013 description: |
0014 The UCD90320 is a 32-rail PMBus/I2C addressable power-supply sequencer and
0015 monitor. The 24 integrated ADC channels (AMONx) monitor the power supply
0016 voltage, current, and temperature. Of the 84 GPIO pins, 8 can be used as
0017 digital monitors (DMONx), 32 to enable the power supply (ENx), 24 for
0018 margining (MARx), 16 for logical GPO, and 32 GPIs for cascading, and system
0019 function.
