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