| Description |
| ----------- |
| |
| From the datasheet: |
| |
| "The EMC6W201 is an environmental monitoring device with automatic fan |
| control capability and enhanced system acoustics for noise suppression. |
| This ACPI compliant device provides hardware monitoring for up to six |
| voltages (including its own VCC) and five external thermal sensors, |
| measures the speed of up to five fans, and controls the speed of |
| multiple DC fans using three Pulse Width Modulator (PWM) outputs. Note |
| that it is possible to control more than three fans by connecting two |
| fans to one PWM output. The EMC6W201 will be available in a 36-pin |
| QFN package." |
| |
| The device is functionally close to the EMC6D100 series, but is |
| register-incompatible. |
| |
| The driver currently only supports the monitoring of the voltages, |
| temperatures and fan speeds. Limits can be changed. Alarms are not |
| supported, and neither is fan speed control. |
