ADT7475 - dBCool Remote Thermal Monitor and Fan Controller

Datasheet Summary

Description

The ADT7475 dBCool controller is a thermal monitor and multiple PWM fan controller for noise-sensitive or powersensitive applications requiring active system cooling.

Features

  • Controls and monitors up to 4 fans High and low frequency fan drive signal 1 on-chip and 2 remote temperature sensors Extended temperature measurement range, up to 191°C 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 Monitors performance impact of Intel® Pentium® 4 processor Thermal control circuit via THERM input 3-wire and 4-wire.
