ADT7475  
dBCOOLR Remote Thermal  
Monitor and Fan Controller  
The ADT7475 dBCOOL controller is a thermal monitor and  
multiple PWM fan controller for noise−sensitive or power−sensitive  
applications requiring active system cooling. The ADT7475 can drive  
a fan using either a low or high frequency drive signal, monitor the  
temperature of up to two remote sensor diodes plus its own internal  
temperature, and measure and control the speed of up to four fans so  
that they operate at the lowest possible speed for minimum acoustic  
noise.

MARKING  
DIAGRAM  
The automatic fan speed control loop optimizes fan speed for a  
given temperature. The effectiveness of the system’s thermal solution  
can be monitored using the THERM input. The ADT7475 also  
provides critical thermal protection to the system using the  
bidirectional THERM pin as an output to prevent system or  
component overheating.
