Digital Temperature Sensor, LM77CIM-3, Texas Instruments

The 3 is a digital temperature sensor and thermal window comparator with an I²C Serial Bus interface. The window-comparator architecture of the 3 eases the design of a temperature control system conforming to the ACPI (Advanced Configuration and Power Interface) specification for personal computers. The open-drain Interrupt (INT) output becomes active whenever temperature goes outside a programmable window, while a separate Critical Temperature Alarm (T_CRIT_A) output becomes active when the temperature exceeds a programmable critical limit. The INT output can operate in either comparator or event mode, while the T_CRIT_A output operates in comparator mode only.
