SNIS128C –AUGUST 2002–REVISED MARCH 2013  
LM89 ±0.75°C Accurate, Remote Diode and Local Digital Temperature Sensor  
With Two-Wire Interface  
Check for Samples: LM89

FEATURES  
DESCRIPTION  
The LM89 is an 11-bit digital temperature sensor with  
a 2-wire System Management Bus (SMBus) serial  
interface. The LM89 accurately measures its own  
temperature as well as the temperature of an external  
device, such as processor thermal diode or diode-  
connected transistor such as the 2N3904. The  
temperature of any ASIC can be accurately  
determined using the LM89 as long as a dedicated  
diode (semiconductor junction) is available on the  
target die. The LM89 remote sensor accuracy of  
±0.75°C is factory trimmed for the series resistance  
and 1.0021 typical nonideality factor of the  
IntelPentium 4 and the Mobile Pentium 4 Processor-  
M thermal diode. The LM89 has an Offset register to  
allow measuring other diodes without requiring  
continuous software management. Visit www.ti.com

•

Management  
(For Example, Laptop, Desktop, Workstations,  
Server)  
The LM89 and the LM89-1 have the same functions  
but different SMBus slave addresses. This allows for  
one of each to be on the bus at the same time.  
Activation of the ALERT output occurs when any  
temperature goes outside a preprogrammed window  
set by the HIGH and LOW temperature limit registers  
or exceeds the T_CRIT temperature limit. Activation  
of the T_CRIT_A occurs when any temperature  
exceeds the T_CRIT programmed limit. The LM89 is  
pin and register compatible with the LM86, LM90,  
Analog Devices ADM1032 and Maxim MAX6657/8.
