+description: |
+ The LM25066 family of power-management ICs (a.k.a. hot-swap
+ controllers or eFuses in various contexts) are PMBus devices that
+ offer temperature, current, voltage, and power monitoring.

+title: UCD90320 power sequencer
+
+maintainers:
+ - Jim Wright <wrightj@linux.vnet.ibm.com>
+
+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.
