... EMC1072 and using that data to control the speed of one or more fans. The EMC1072 has two levels of monitoring. The first provides a maskable ALERT signal to the host when the measured temperatures exceeds user programmable limits. This allows the EMC1072 to be used as an independent thermal watchdog to warn the host of temperature hot spots without direct control by the host ...

... Dynamic Averaging Dynamic averaging causes the EMC1072 to measure the external diode channels for an extended time based on the selected conversion rate. This functionality can be disabled for increased power savings at the lower conversion rates (see enabled, the device will automatically adjust the sampling and measurement time for the external diode channels ...

... When the ALERT pin is configured to operate in comparator mode it will be asserted if any of the measured temperatures exceeds the respective high limit. The ALERT pin will remain asserted until all temperatures drop below the corresponding high limit minus the THERM Hysteresis value. SMSC EMC1072 Figure 5.2. ...
