NCT7491, Remote Thermal Monitor and Fan Controller

NCT7491 Remote Thermal Monitor and Fan Controller with PECI 3.0 Interface and SMBus Compatible Master The NCT7491 is a two wire serially programmable hardware monitor.

It can monitor 2 remote temperature zones and its own ambient temperature.

A PECI 3.0 single wire interface allows the NCT7491 to monitor CPU temperatures.

The NCT7491 also implements an SMBus compatible master, allowing it to read automatically from thermal sensors on the SMBus.

The NCT7491 can automatically control the
