1.1.2.12 Thermal Sensor_ ADM1021A
The ADT7460 dBCOOL
sensitive applications requiring active system cooling. It can monitor the temperature of up to 2 remote sensor
diodes, plus its own internal temperature. It can measure and control the speed of up to 4 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 TMIN 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 ADT7460 also provides critical Thermal Protection to the system
using the bidirectional THERM pin as an output to prevent system or component overheating.
