GENERAL DESCRIPTION
The ADT7466
dB
Cool controller is a complete thermal monitor
and dual fan controller for noise-sensitive applications
requiring active system cooling. It can monitor two analog
voltages or the temperature of two thermistors, 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 two 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. The effectiveness of the system’s
thermal solution can be monitored using the PROCHOT input
to time and monitor the PROCHOT output of the processor.
