dbCOOL Remote Thermal

Monitor and Fan Controller

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.

given temperature. A unique dynamic T

control mode enables the

MIN

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.
