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.
