0.5藲C,
鹵
1藲C, 12-Bit + Sign Digital Temperature Sensor
and Thermal Window Comparator with Two-Wire
Interface
General Description
The LM76 is a digital temperature sensor and thermal win-
dow comparator with an I
2
C
鈩?/div>
Serial Bus interface with an
accuracy of
鹵
1藲C. This accuracy for the LM76CHM is speci-
fied for a 鈭?0藲C to 45藲C temperature range, while for the
LM76CNM the temperature range is 70藲C to 100藲C. The
LM76CHM is specified with an accuracy
鹵
0.5藲C at 25藲C. The
window-comparator architecture of the LM76 eases the de-
sign of temperature control systems conforming to the ACPI
(Advanced Configuration and Power Interface) specification
for personal computers. The open-drain Interrupt (INT) out-
put becomes active whenever temperature goes outside a
programmable window, while a separate Critical Tempera-
ture 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. Program-
mable hysterisis as well as a fault queue are available to
minimize false tripping. Two pins (A0, A1) are available for
address selection. The sensor powers up with default thresh-
olds of 2藲C T
HYST
, 10藲C T
LOW
, 64藲C T
HIGH
, and 80藲C
T_CRIT.
The LM76鈥檚 3.3V and 5.0V supply voltage, Serial Bus inter-
face, 12-bit + sign output, and full-scale range of over 127藲C
make it ideal for a wide range of applications. These include
thermal management and protection applications in personal
computers, electronic test equipment, office electronics and
bio-medical applications.
