Power chip

The ADT7473/ADT7473-1 controller is a thermal supervisor and multiple PWM fan controller for noise-sensitive or power-sensitive applications requiring active system cooling. The ADT7473/ADT7473-1 can drive fans with low or high frequency drive signals, monitor the temperature of up to two remote sensor diodes and its own internal temperature, and can measure and control the speed of up to four fans so that they operate at the lowest speed possible operation for the lowest noise.
