ADT7473 - dBCool Remote Thermal Monitor and Fan Controller

Datasheet Summary

Description

The ADT7473 dBCool controller is a thermal monitor and multiple PWM fan controller for noise sensitive or power sensitive 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 Series resistance cancellation on the remote channel Extended temperature measurement range, up to 191°C Dynamic TMIN control 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 out.
