FAN CONTROL LOOK-UP TABLE

The EMC2101 uses an 8-entry look-up table to apply a

user-programmable fan control profile based on

measured temperature. The user programs the Fan

Control Look-Up Table using incrementally higher

temperatures and the desired fan output that should be

set when that temperature is reached.

If the measured temperature on the External Diode

channel exceeds any of these temperature thresholds,

the fan output will be automatically programmed to the

desired setting corresponding to the exceeded tem-

perature. When the measured temperature drops to a

point below any lower threshold minus the hysteresis

value, the fan output will be set to the corresponding

lower set point.

Figure 4-7 shows an example of this operation.

If the Fan Control Look-Up Table is not used, the user

may program the Fan Output directly by writing to the

Fan Setting Register (4Ch - see Register 5-16).
