1. Ctup, Ctdn Can be Programmed to 1, ½, ¼, 0  
2. Ta Can be Selected to the Same Temp. Source (Ex:T1)  
TFan1= T1 + (Ta-Tb)*Ctup ; TFan1= T1 + (Ta-Tb)*Ctdn  
Figure 7-14  
In application, we can set the Ta as the 2nd sensor temperature and Tb as the temperature which  
starts the scaling. So if the 2nd sensor temperature Ta is higher or lower than Tb, the fan1 speed  
would be changed with it.  
EX: Ta = T1, Tb = 60, Ctu = 1, Ctd = 1/4
