General Description  
The LM86 is an 11-bit digital temperature sensor with a  
2-wire System Management Bus (SMBus) serial interface.  
The LM86 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 LM86 as long as a dedicated diode  
(semiconductor junction) is available on the target die. The  
LM86 remote sensor accuracy of 0.75˚C is factory trimmed  
for the 1.008 typical non-ideality factor of the mobile Pen-

Activation of the ALERT output occurs when any tempera-  
ture 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 LM86 is pin and register compatible with the the Analog  
Devices ADM1032 and Maxim MAX6657/8.
