Key Features

The ADT7476ARQZ-REEL is a thermal monitor and PWM fan controller designed for noise-sensitive or power-sensitive applications requiring active system cooling. It can drive fans using either low or high frequency signals and monitor temperatures from up to two remote sensor diodes in addition to its internal temperature sensor. The device measures and controls the speed of up to four fans, ensuring they operate at the lowest possible speed to minimize acoustic noise. Its automatic fan speed control mode adjusts system cooling based on measured temperatures, while the enhanced acoustic mode reduces user perception of changing fan speeds. The ADT7476 also features thermal protection via the THERM output and meets SMBus 2.0 electrical specifications.​

Applications

Notebook and desktop computers
Servers
Game consoles
RFID readers​
