DESCRIPTION
The LM76 is a digital temperature sensor and thermal
window comparator with an I2C Serial Bus interface
with an accuracy of ±1°C. This accuracy for the
LM76CHM is specified for a 10°C to 45°C
temperature range. The LM76CHM is specified with
an accuracy ±0.5°C at 25°C. The window-comparator
architecture of the LM76 eases the design of
temperature control systems conforming to the ACPI
(Advanced Configuration and Power Interface)
specification for personal computers. The open-drain
Interrupt (INT) output becomes active whenever
temperature goes outside a programmable window,
while a separate Critical Temperature 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.
Programmable 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 thresholds of 2°C THYST, 10°C
TLOW, 64°C THIGH, and 80°C T_CRIT.
The LM76's 5.0V supply voltage, Serial Bus interface,
12-bit + sign output, and full-scale range of over
127°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.
