资 源 简 介
The LM77 is a digital temperature sensor and thermal windowcomparator with an I2C™ Serial Bus interface. Thewindow-comparator architecture of the LM77 eases the designof temperature control systems conforming to the ACPI(Advanced ConfiguraTIon and Power Interface) specificaTIonfor personal computers. The open-drain Interrupt (INT) outputbecomes acTIve whenever temperature goes outside aprogrammable window, while a separate CriTIcal TemperatureAlarm (T_CRIT_A) output becomes active when thetemperature exceeds a programmable critical limit. The INToutput can operate in either a comparator or event mode,while the T_CRIT_A output operates in comparator modeonly.
