1 / 22 page LM76 www.ti.com SNIS109E – JANUARY 2000 – REVISED MARCH 2013 LM76 ±0.5°C, ±1°C, 12-Bit + Sign Digital Temperature Sensor and Thermal Window Comparator with Two-Wire Interface Check for Samples: LM76 1 FEATURES DESCRIPTION The LM76 is a digital temperature sensor and thermal 2 • Window Comparison Simplifies Design of window comparator with an I2C Serial Bus interface ACPI Compatible Temperature Monitoring and with an accuracy of ±1°C. This accuracy for the Control. LM76CHM is specified for a −10°C to 45°C • Serial Bus Interface temperature range. The LM76CHM is specified with an accuracy ±0.5°C at 25°C. The window-comparator • Separate Open-Drain Outputs for Interrupt and architecture of the LM76 eases the design of Critical Temperature Shutdown temperature control systems conforming to the ACPI • Shutdown Mode to Minimize Power (Advanced Configuration and Power Interface) Consumption specification for personal computers. The open-drain • Up to 4 LM76s can be Connected to a Single Interrupt (INT) output becomes active whenever Bus temperature goes outside a programmable window, while a separate Critical Temperature Alarm • 12-bit + Sign Output; Full-scale Reading of (T_CRIT_A) output becomes active when the Over 127°C temperature exceeds a programmable critical limit. The INT output can operate in either a comparator or KEY SPECIFICATIONS event mode, while the T_CRIT_A output operates in • Supply Voltage 5.0V comparator mode only. • Supply Current The host can program both the upper and lower limits of the window as well as the critical temperature limit. – Operating Programmable hysterisis as well as a fault queue are – 250 µA (typ) available to minimize false tripping. Two pins (A0, A1) – 450 µA (max) are available for address selection. The sensor – Shutdown powers up with default thresholds of 2°C THYST, 10°C TLOW, 64°C THIGH, and 80°C T_CRIT. – 8 µA (max) The LM76's 5.0V supply voltage, Serial Bus interface, • Temperature +25ºC ±0.5ºC (max) 12-bit + sign output, and full-scale range of over – Accuracy 127°C make it ideal for a wide range of applications. – –10ºC to +45ºC ±10°C (max) These include thermal management and protection – 70°C to 100°C ±1.0°C (max) applications in personal computers, electronic test equipment, office electronics and bio-medical • Resolution 0.0625°C applications. APPLICATIONS • System Thermal Management • Personal Computers • Office Electronics • HVAC 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
