Fan Controller/Driver with Factory-  
Programmed Temperature Thresholds  
General Description  
Features  
The MAX6665 is a fully integrated thermal switch with  
an internal power transistor for driving a cooling fan  
rated up to 24V and 250mA. When the MAX6665’s tem-  
perature rises above a factory-programmed threshold,  
the FANOUT pin becomes active and powers the fan.  
On-Chip 250mA Fan Switch  
No External Components Required  
Factory-Programmed Thresholds  
Two Overtemperature Warning Signals  
Pin-Selectable 1°C, 4°C, and 8°C Hysteresis  
Low 65µA Supply Current  
The MAX6665 is available with factory-programmed fan  
activation threshold temperatures from +40°C to +70°C  
in 5°C increments. Accuracy of the fan activation trip  
point is ±±°C ꢀtypꢁ and ±°C ꢀmaꢃꢁ. The trip point’s hys-  
teresis is pin selectable to ±°C, 4°C, or 8°C. Two open-  
drain logic outputs indicate overtemperature con-  
ditions: WARN is activated when the temperature is  
±5°C above the fan activation threshold, and OT is acti-  
vated when the temperature is ꢂ0°C above the thresh-  
old. These features can be used to safely power down  
systems that are overheated.
