Temp Monitoring and Fan Control with bios Support

Hi Mike,

 I replied yesterday by email - sorry if you are seeing this twice as I noticed today that a reply was not posted.

Take a look at the LM96063. It’s almost identical to the LM96163 (look under National Semiconductor for now I’ll get that changed):

-          Looks like support was just added for the LM96163. The only difference between the two parts is the thermal diode characteristics.

Take care,

Emmy

Hello Mike,

The AMC6821 is a controller with many functions for 2,3,4-wire fans that is programmed with I2C/SMBUS. It is typically used to:
- Measure external sensor temperature and react independently to changes by increasing the fan speed (stand-alone after programming registers)
- Regulate/monitor fan speed (stand-alone after programming registers)
- Detect/inform of critical events with SMBus alerts and hardware triggers.

If stand-alone mode is not required, it can simply record temperature and set fan speed according to the master (bios).

Also, a linux driver from free-electrons.com was mentioned in another post:

Although we don’t support this driver, we can answer any question you may have regarding the AMC6821 functionality, and which registers to program for your particular application. Just make a post in the Precision-Data-Converters forum:
