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 tempera-
ture. 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 T
MIN
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.
