LM77 9-Bit + Sign Digital Temperature Sensor and Thermal Window Comparator with

Two-Wire Interface

Check for Samples: LM77

FEATURES

DESCRIPTION

The LM77 is a digital temperature sensor and thermal

window comparator with an I²C Serial Bus interface.

The window-comparator architecture of the LM77

eases the design of temperature control systems

conforming to the ACPI (Advanced Configuration and

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

exceeds

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.

9-bit + Sign Output; Full-Scale Reading of Over

128°C

SOIC and VSSOP 8-lead Packages

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 T_HYST, 10°C

T_LOW, 64°C T_HIGH, and 80°C T_CRIT.

APPLICATIONS

•

System Thermal Management

Personal Computers

Office Electronics

Electronic Test Equipment

Automotive

The LM77's 3.0V to 5.5V supply voltage range, Serial

Bus interface, 9-bit + sign output, and full-scale range

of over 128°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,

automotive, and HVAC applications.
