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.

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
