ADT7475 dBCool Remote Thermal Monitor and Fan Controller

The ADT7475 dBCool controller is a thermal monitor and multiple PWM fan controller for noise-sensitive or powersensitive 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 dio.

ADT7475 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
