GENERAL DESCRIPTION
The ADT7463
dB
COOL 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 mea-
sure 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
Con-
trol 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 bidirec
tional
THERM
pin as an output to
prevent system or
component overheating.
