dBCool Remote Thermal  
Monitor and Fan Controller  
ADT7467  
FEATURES  
GENERAL DESCRIPTION  
Controls and monitors up to 4 fans  
The ADT7467 dBCool® controller is a thermal monitor and  
multiple PWM fan controller for noise-sensitive or power-  
sensitive applications requiring active system cooling. The  
ADT7467 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.  
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 manages system cooling  
based on measured temperature  
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 solution can  
be monitored using the THERM input. The ADT7467 also  
provides critical thermal protection to the system using the  
bidirectional THERM pin as an output to prevent system or  
component overheating.  
Enhanced acoustic mode dramatically reduces user  
perception of changing fan speeds
