and Thermal Window Comparator with T wo-Wire
Interface
General DescriptionThe LM76isa digital temperature sensor and thermal win-
dow comparator withanI2C™ Serial Bus interface withan
accuracyof ±1˚C. This accuracyforthe LM76CHMis speci-
fiedfora −10˚Cto 45˚C temperature range, whilefor the
LM76CNM the temperature rangeis 70˚Cto 100˚C. The
LM76CHMis specified withan accuracy ±0.5˚Cat 25˚C. The
window-comparator architectureofthe LM76 eases the de-
signof temperature control systems conformingtothe ACPI
(Advanced Configuration and Power Interface) specification
for personal computers. The open-drain Interrupt (INT) out-
put becomes active whenever temperature goes outsidea
programmable window, whilea separate Critical Tempera-
ture Alarm (T_CRIT_A) output becomes active when the
temperature exceedsa programmable critical limit. The INT
output can operatein eithera comparatoror event mode,
while the T_CRIT_A output operatesin comparator mode
only.
The host can program boththe upper and lower limitsofthe
windowas wellas the critical temperature limit. Program-
mable hysterisisas wellasa fault queue are availableto
minimize false tripping. Two pins (A0, A1) are availablefor
address selection. The sensor powersup withdefault thresh-
oldsof 2˚C THYST, 10˚C TLOW, 64˚C THIGH, and 80˚C
T_CRIT.
The LM76’s 3.3V and 5.0V supply voltage, Serial Bus inter-
face, 12-bit+ sign output, and full-scale rangeof over 127˚C
makeit idealfora wide rangeof applications. These include
thermal management and protection applicationsin personal
computers, electronic test equipment, office electronics and
bio-medical applications.
Features Window comparison simplifies designof ACPI
compatible temperature monitoring and control. Serial Bus interface Separate open-drain outputsfor Interrupt and Critical
Temperature shutdown Shutdown modeto minimize power consumption Upto4 LM76s canbe connectedtoa single bus 12-bit+ sign output; full-scale readingof over 127˚C
