dBCOOL™Remote Thermal  
Controller and Fan Controller  
ADT7460  
FEATURES  
GENERAL DESCRIPTION  
Controls and monitors up to 4 fan speeds  
1 on-chip and 2 remote temperature sensors  
Dynamic TMIN control mode optimizes system acoustics  
intelligently  
Automatic fan speed control mode controls system cooling  
based on measured temperature  
Enhanced acoustic mode dramatically reduces user  
perception of changing fan speeds  
Thermal protection feature via THERM output  
The ADT74601 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 temp-  
erature. 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 unique dynamic TMIN  
control mode enables the system thermals/acoustics to be  
intelligently managed. The effectiveness of the system’s thermal  
Monitors performance impact of Intel® Pentium® 4  
Processor thermal control circuit via THERM input  
2-wire and 3-wire fan speed measurement  
Limit comparison of all monitored values  
Meets SMBus 2.0 electrical specifications (fully  
SMBus 1.1-compliant)  
solution can be monitored using the  
input. The  
THERM  
ADT7460 also provides critical thermal protection to the  
system by using the bidirectional pin as an output  
THERM  
to prevent system or component overheating.  
APPLICATIONS  
Low acoustic noise PCs  
Networking and telecommunications equipment
