LM92

0.33˚C Accurate, 12-Bit + Sign Temperature Sensor and

Thermal Window Comparator with Two-Wire Interface

n Shutdown mode to minimize power consumption

n Up to 4 LM92s can be connected to a single bus

n 12-bit + sign output

n Operation up to 150˚C

General Description

The LM92 is a digital temperature sensor and thermal win-

™

dow comparator with an I C Serial Bus interface and an

accuracy of 0.33˚C. The window-comparator architecture

of the LM92 eases the design of temperature control sys-

tems. The open-drain Interrupt (INT) output becomes active

whenever temperature goes outside a programmable win-

(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˚C T_HYST, 10˚C T_LOW, 64˚C T_HIGH, and 80˚C

T_CRIT.

n Linearity

The LM92’s 2.7V to 5.5V supply voltage range, Serial Bus in-

terface, 12-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 elec-

tronics, automotive, medical and HVAC applications.
