The LM77CIMM-3/NOPB is a Digital Temperature Sensor with thermal window comparator and an I2C serial bus interface. The window-comparator architecture of the LM77 eases the design of temperature control systems 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 a comparator or event mode, while the T_CRIT_A output operates in comparator mode only. The host can program both the upper and lower limits of the window as well as the critical temperature limit. Programmable hysteresis as well as a fault queue is available to minimize false tripping. Two pins (A0, A1) are available for address selection.

• Window comparison simplifies design of ACPI compatible temperature monitoring and control
• Separate open-drain outputs for interrupt and critical temperature shutdown
• Shutdown mode to minimize power consumption
• Up to 4 devices can be connected to a single bus
• 9-bit + Sign output
• Full-scale reading of over 128°C
• Green product and no Sb/Br
