±0.33°C Accurate, 12-Bit + Sign Temperature Sensor and Thermal Window Comparator with Two-Wire Interface
LM92
±0.33˚C Accurate, 12-Bit + Sign Temperature Sensor and
Thermal Window Comparator with Two-Wire Interface
General DescriptionThe LM92isa digital temperature sensor and thermal win-
dow comparator withanI2C™ Serial Bus interface andan
accuracyof ±0.33˚C. The window-comparator architecture the LM92 eases the designof temperature control sys-
tems. The open-drain Interrupt (INT) output becomes active
whenever temperature goes outsidea programmable win-
dow, whilea separate Critical Temperature 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 LM92’s 2.7Vto 5.5V supply voltage range, Serial Bus
interface, 12-bit+ sign output, and full-scale rangeof over
128˚C makeit idealfora wide rangeof applications. These
include thermal management and protection applicationsin
personal computers, electronic test equipment, office elec-
tronics, automotive, medical and HVAC applications.
Features Window comparison simplifies designof ACPI
compatible temperature monitoring and control. Serial Bus interface Separate open-drain outputsfor Interrupt and Critical
