ADT7476A - dBCool Remote Thermal Controller and Voltage Monitor

Description

The ADT7476A dBCOOL controller is a thermal monitor and multiple PWM fan controller for noise-sensitive or powersensitive applications requiring active system cooling.

Features

  • Monitors up to five voltages Improved TACH and PWM performance Controls and monitors up to four fans High and low frequency fan drive signal One on-chip and two 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®.
