Overview
ADT7473 Remote Thermal Monitor and Fan Control The ADT7473/ADT7473−1 controller is a thermal monitor and multiple PWM fan controller for noise sensitive or power sensitive applications requiring active system cooling.
The ADT7473/ADT7473−1 can drive a fan using either a low or high frequency drive signal, monitor the temperature of up to two remote sensor diodes plus its own internal temperature, and measure and control the speed of up to four fans so they operate at the lowest possible speed for minimum acoustic noise.
The automatic fan speed control loop optimizes fan speed for a given temperature.
A unique dynamic TMIN control mode enables the system thermals/acoustics to be intelligentl...
