dBCool® Remote Thermal  
Controller and Voltage Monitor  
ADT7466  
FEATURES  
GENERAL DESCRIPTION  
Monitors two analog voltages or thermistor temperature  
inputs  
The ADT7466 dBCool controller is a complete thermal monitor  
and dual fan controller for noise-sensitive applications  
requiring active system cooling. It can monitor two analog  
voltages or the temperature of two thermistors, plus its own  
supply voltage. 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 two 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. The effectiveness of the systems  
One on-chip and up to two remote temperature sensors with  
series resistance cancellation  
Controls and monitors the speed of up to two fans  
Automatic fan speed control mode controls system  
cooling based on measured temperature  
Enhanced acoustic mode dramatically reduces user  
perception of changing fan speeds
