| 13 | description: | |
| 14 | The UCD90320 is a 32-rail PMBus/I2C addressable power-supply sequencer and |
| 15 | monitor. The 24 integrated ADC channels (AMONx) monitor the power supply |
| 16 | voltage, current, and temperature. Of the 84 GPIO pins, 8 can be used as |
| 17 | digital monitors (DMONx), 32 to enable the power supply (ENx), 24 for |
| 18 | margining (MARx), 16 for logical GPO, and 32 GPIs for cascading, and system |
| 19 | function. |
