LM77 9-Bit+ Sign Digital Temperature Sensor and Thermal Window Comparator with
Two-Wire Interface
Checkfor Samples: LM77
1FEATURES DESCRIPTIONThe LM77isa digital temperature sensor and thermal
Window Comparison Simplifies Designof window comparator with anI2C Serial Bus interface.
ACPI Compatible Temperature Monitoring and The window-comparator architecture of the LM77
Control. eases the design of temperature control systems
• Serial Bus Interface conformingto the ACPI (Advanced Configuration and
Power Interface) specification for personal
• Separate Open-Drain Outputs for Interrupt andcomputers. The open-drain Interrupt (INT) output
Critical Temperature Shutdown becomes active whenever temperature goes outside
• Shutdown Modeto Minimize Power a programmable window, whilea separate Critical
Consumption Temperature Alarm (T_CRIT_A) output becomes
Upto4 LM77s Can be Connectedtoa Single active when the temperature exceeds a
Bus programmable critical limit. The INT output can
operatein eithera comparatoror event mode, while
• 9-bit+ Sign Output; Full-Scale Readingof Over the T_CRIT_A output operatesin comparator mode
128°C only.
• SOIC and VSSOP 8-lead Packages The host can program both the upper and lower limits the windowas wellas the critical temperature limit.
APPLICATIONS Programmable hysterisisas wellasa fault queue are
