The NCT7718W is an SMBus based temperature sensor with one local and one remote sensor input. The remote temperature sensor input can be connected to a thermal diode or transistor such as 2N3904 and the internal 10-bit Analog-to-Digital Converter can provide temperature measurements with  0.125℃ resolution.

Additionally, the NCT7718W provides hardware thermal alert and system shutdown via ALERT# and T_CRIT# pin.

The NCT7718W is a high precision, low-power IC specifically designed for the PC, Notebook, and Embedded market.
