dBCool^®Remote Thermal

Controller and Voltage Monitor

ADT7466

FEATURES

GENERAL DESCRIPTION

Monitors two analog voltages or thermistor temperature

inputs

The ADT7466 dBCool 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

One on-chip and up to two remote temperature sensors with

series resistance cancellation

Controls and monitors the speed of up to two fans

Automatic fan speed control mode controls system

cooling based on measured temperature

Enhanced acoustic mode dramatically reduces user

perception of changing fan speeds
