Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver implements support for Monolithic Power Systems, Inc. (MPS)
|
||
|
|
vendor dual-loop, digital, multi-phase controller MP2888.
|
||
|
|
|
||
|
|
This device: supports:
|
||
|
|
|
||
|
|
- One power rail.
|
||
|
|
- Programmable Multi-Phase up to 10 Phases.
|
||
|
|
- PWM-VID Interface
|
||
|
|
- One pages 0 for telemetry.
|
||
|
|
- Programmable pins for PMBus Address.
|
||
|
|
- Built-In EEPROM to Store Custom Configurations.
|
||
|
|
|
||
|
|
Device complaint with:
|
||
|
|
|
||
|
|
- PMBus rev 1.3 interface.
|
||
|
|
|
||
|
|
Device supports direct format for reading output current, output voltage,
|
||
|
|
input and output power and temperature.
|
||
|
|
Device supports linear format for reading input voltage and input power.
|
||
|
|
|
||
|
|
The driver provides the next attributes for the current:
|
||
|
|
|
||
|
|
- for current out input and maximum alarm;
|
||
|
|
- for phase current: input and label.
|
||
|
|
|
||
|
|
The driver exports the following attributes via the 'sysfs' files, where:
|
||
|
|
|
||
|
|
- 'n' is number of configured phases (from 1 to 10);
|
||
|
|
- index 1 for "iout";
|
||
|
|
- indexes 2 ... 1 + n for phases.

The driver provides the next attributes for the voltage:
|
||
|
|
|
||
|
|
- for voltage in: input, low and high critical thresholds, low and high
|
||
|
|
critical alarms;
|
