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  
QSOP−16  
CASE 492  
given temperature. A unique dynamic T  
control mode enables the  
MIN  
system thermals/acoustics to be intelligently managed. The  
effectiveness of the system’s thermal solution can be monitored using  
the THERM input. The ADT7473/ADT7473−1 also provide critical  
thermal protection to the system using the bidirectional THERM pin  
as an output to prevent system or component overheating.
