LM89  
SNIS128D –AUGUST 2002–REVISED JUNE 2014  
LM89 ±0.75°C Accurate, Remote Diode And Local Digital Temperature Sensor  
With Two-Wire Interface  
1 Features  
3 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, GPU, FPGA or MCU can  
be accurately determined using the LM89 as long as

T_CRIT_A Output Useful for System Shutdown  
ALERT Output Supports SMBus 2.0 Protocol  
available on the target die. The LM89 has an Offset  
register to allow calibration for different nonideality  
factors without requiring software management.  
SMBus 2.0 Compatible Interface, Supports  
TIMEOUT  
Activation of the ALERT occurs when any  
temperature goes outside a preprogrammed window  
set by the HIGH and LOW limit registers or exceeds  
the T_CRIT limit. Activation of the T_CRIT_A occurs  
when any temperature exceeds the T_CRIT  
programmed limit.

Supply Voltage: 3.0 V to 3.6 V  
Local Temp Accuracy (includes quantization  
error)  
The LM89 is pin and register compatible with the  
LM86, LM90, LM99, On Semiconductor ADM1032  
and Maxim MAX6657/8.  
–
TA = 25°C to 125°C ±3.0 °C (max)  
–
Remote Diode Temp Accuracy (includes  
quantization error)  
The LM89C and the LM89-1C have the same  
functions but different SMBus slave addresses,  
allowing multiple LM89's on a bus. LM89-1D's default  
local T_CRIT temperature limit is 105°C; all other  
versions are 85°C. (See Device Comparison Table.)

TA = 30°C, TD = 80°C ±0.75 °C (max)
