Power chip

The ADT7460 is a temperature monitor and multiplex PWM fan controller for noise sensitive applications requiring active system cooling. It monitors the temperature of up to two remote sensor diodes as well as its own internal temperature. It can measure and control the speed of up to four fans, running them at the lowest speed possible for the lowest noise. An automatic fan speed control loop optimizes fan speed at a given temperature. Unique dynamic Tmin control mode enables intelligent management of system temperature/sound. Using the THERM input, the effectiveness of the system cooling scheme can be monitored. The ADT7460 also provides important high temperature protection for the system by using the bidirectional THERM pin as an output in case the system or components overheat.
