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 T MIN control mode enables the
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.
