GENERAL DESCRIPTION

The ADT7463 dBCOOL controller is a complete systems

monitor and multiple PWM fan controller for noise-sensitive

applications requiring active system cooling. It can monitor

12 V, 5 V, and 2.5 V CPU supply voltages, 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 four 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.

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 ADT7463 also provides critical thermal

protection to the system using the bidirectional THERM pin

as an output to prevent system or component overheating.

*Protected by U.S. Patent Nos. 6,188,189; 6,169,442; 6,097,239; 5,982,221; and 5,867,012. Other patents pending.
