Fan Driver
SMBus Alert Protocol (ARA) Support
Other EMC1001 Features
The fan driver utilizes the
speeds. See the Circuit Description above for information about the fan driver. Plug the 3 pin connector
for the supplied fan assmembly into P2 on the EVB.
Normally, the fan driver is OFF. To turn the fan ON at low speed, the
asserted low. This can be caused by dragging the High Temp Limit line below the current temperature
on the Zone Temperature History graph, using the Register Manager to set the High Temp Limit value
lower than the current temperature or heating the temp sensor to exceed the limit.
To turn the fan ON to high speed, the
the current temperature exceeds the associated THERM limit.
Note: When
When the
will turn RED on the Register Manager panel. Press the Response button to cause RegMan to send
the SMBus Alert Address to the EMC1001. The EMC1001 will respond with it’s SMBus address which
is displayed in a text box next to the Response button on the RegMan interface. If the temperature is
still above the limit, the indicator will remain lit and the
temperature is below the limit the indicator will turn OFF and the
Other features such as Conversion Rate, Standby Mode, Interrupt Mask and
controlled with EMC1001 registers. See the EMC1001 datasheet register description for details.
