NCT7718W - Thermal Sensor IC - Nuvoton Даташит

GENERAL DESCRIPTION
NCT7718W is a temperature sensor with one local and one remote sensor; the remote temperature sensor input could be connected to thermal diode or transistor, such as 2N3904. A 10-bit ADC (Analog-to-Digital Converter) is built inside NCT7718W to convert the monitored temperature value with 0.125°C resolution.
Additionally, the NCT7718W supports 2-wire System Management Bus (SMBusTM) series interface, and it also provides the hardware thermal alert or system shutdown via ALERT# and T_CRIT# pin. 
The NCT7718W is a high precision, low-power consumption IC supporting SMBusTM interface, which is specifically designed for the PC, Notebook applications, and any embedded environments. Its available package is 8-pin MSOP, with the working voltage of 3.3V.
