dBCool^™Remote Thermal

Monitor and Fan Controller

ADT7475

Preliminary Technical Data

FEATURES

GENERAL DESCRIPTION

Controls and monitors up to 4 fans

High and low frequency fan drive signal

The ADT7475 dBCOOL^TMcontroller is a thermal monitor and

multiple PWM fan controller for noise-sensitive or power-

sensitive applications requiring active system cooling. The

ADT7475 can drive a fan using either a low or high frequency

drive signal, monitor the temperature of up to two remote

sensor diodes plus its own internal temperature, and measure

and control the speed of up to four fans, so that they operate at

the lowest possible speed for minimum acoustic noise.

1 on-chip and 2 remote temperature sensors

Series resistance cancellation on the remote channel

Extended temperature measurement range, up to 191°C

Dynamic T_MINcontrol mode optimizes system acoustics

intelligently

Automatic fan speed control mode controls system cooling

based on measured temperature

Enhanced acoustic mode dramatically reduces user

perception of changing fan speeds

Thermal protection feature via THERM output

The automatic fan speed control loop optimizes fan speed for a

given temperature. A unique dynamic T_MINcontrol mode

enables the system thermals/acoustics to be intelligently

managed. The effectiveness of the system's thermal solution can
