ADT7463
Remote Thermal Controller
and Voltage Monitor
The ADT7463 controller is a complete systems monitor and
multiple PWM fan controller for noisesensitive applications
requiring active system cooling. It can monitor 12 V, 5 V, and 2.5 V
CPU supply voltages, plus its own supply voltage. It can monitor the
temperature of up to two remote sensor diodes, plus its own internal
temperature. It can measure and control the speed of up to four fans so
that 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 systems thermal solution can be monitored using
the THERM
input. The ADT7463 also provides critical thermal
protection to the system using the bidirectional THERM
pin as an
output to prevent system or component overheating.
