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
nonideality factor of the mobile Pentium? III thermal
diode. The LM86 has an Offset register to allow measuring other diodes without requiring continuous
software management. Contact
hardware.monitor.team@nsc.com to obtain the latest
data for new processors.
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 LM86 is
pin and register compatible with the the Analog
Devices ADM1032 and Maxim MAX6657/8.
