ADT7490  
dBCoolR Remote Thermal  
Monitor and Fan Controller  
with PECI Interface  
The ADT7490 is a dBCool thermal monitor and multiple PWM fan  
controller for noisesensitive or powersensitive applications  
requiring active system cooling. The ADT7490 includes a local  
temperature sensor, two remote temperature sensors including series  
resistance cancellation, and monitors CPU temperature with a PECI  
interface. The ADT7490 can drive a fan using either a low or high  
frequency drive signal, and measure and control the speed of up to four  
fans so they operate at the lowest possible speed for minimum acoustic  
noise.

QSOP24 NB  
CASE 492B  
The automatic fan speed control loop optimizes fan speed  
for a given temperature using the PECI, remote, or local temperature  
information. The effectiveness of the system’s thermal solution can be  
monitored using the THERM input. The ADT7490 also provides  
critical thermal protection to the system using the bidirectional  
THERM/SMBALERT pin as an output to prevent system or  
component overheating.
