Hot-selling and scarce ADT7473ARQZ Remote Thermal Monitor and Fan Control IC QSOP-16 spot stock

Product Descriptions

The  ADT7473/ADT7473−1  dBCOOL  controller  is  a  thermalmonitor and multiple PWM fan controller for noise sensitive or powersensitive  applications  requiring  active  system  cooling .  TheADT7473/ADT7473−1 can drive a fan using either a low or highfrequency drive signal, monitor the temperature of up to two remotesensor diodes plus its own internal temperature, and measure andcontrol the speed of up to four fans so they operate at the lowestpossible speed for minimum acoustic noise .

The automatic fan speed control loop optimizes fan speed for agiven temperature.A unique dynamic T MIN control mode enables thesystem  thermals/acoustics  to  be  intelligently  managed .  Theeffectiveness of the system’s thermal solution can be monitored usingthe THERM input . The ADT7473/ADT7473−1 also provide criticalthermal protection to the system using the bidirectional THERM pinas an output to prevent system or component overheating .
