ADT7460  
dBCOOLR Remote Thermal  
Monitor and Fan Controller  
The ADT7460 dBCOOL controller is a thermal monitor and  
multiple PWM fan controller for noise−sensitive applications  
requiring active system cooling. It can monitor the temperature of up  
to two remote sensor diodes plus its own internal temperature. It can  
measure and control the speed of up to four fans so that they operate at  
the lowest possible speed for minimum acoustic noise. The automatic  
fan speed control loop optimizes fan speed for a given temperature. A

thermals/acoustics to be intelligently managed. The effectiveness of  
the system’s thermal solution can be monitored using the THERM  
input. The ADT7460 also provides critical thermal protection to the  
system by using the bidirectional THERM pin as an output to prevent  
system or component overheating.
