Description

The ADT7460 dBCOOL controller is a thermal monitor and multiple PWM fan controller for noise-sensitive applications requiring active system cooling. It can monitor the temperature of up to two remote sensor diodes, plus its own internal temperature.

ADT7460 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 ADT7460 also provides critical Thermal Protection to the system using the bidirectional THERM pin as an output to prevent system or component overheating.
