dBCool Remote Thermal Monitor  
and Fan Controller  
ADT7473/ADT7473-1  
GENERAL DESCRIPTION  
FEATURES  
Controls and monitors up to 4 fans  
The ADT7473/ADT7473-1 dBCool® controller is a thermal  
monitor and multiple PWM fan controller for noise sensitive  
or power sensitive applications requiring active system cooling.  
The ADT7473/ADT7473-1 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 they  
operate at the lowest possible speed for minimum acoustic noise.  
High and low frequency fan drive signal  
1 on-chip and 2 remote temperature sensors  
Series resistance cancellation on the remote channel  
Extended temperature measurement range, up to 191°C  
Dynamic TMIN control mode intelligently optimizes system  
acoustics  
Automatic fan speed control mode controls system cooling  
based on measured temperature  
Enhanced acoustic mode dramatically reduces user  
perception of changing fan speeds  
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 systems thermal solution

Meets SMBus 2.0 electrical specifications  
(fully SMBus 1.1 compliant)  
system using the bidirectional  
pin as an output to  
prevent system or component overheating.
