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. |
