ADM1032
+15C Remote and Local
System Temperature Monitor
The ADM1032 is a dual-channel digital thermometer and
under/overtemperature alarm intended for use in PCs and thermal
management systems. The device can measure the temperature of a
remote thermal diode, which can be located on the processor die or can
be a discrete device (2N3904/06), accurate to 1癈. A novel
measurement technique cancels out the absolute value of the
transistors base emitter voltage so that no calibration is required. The
ADM1032 also measures its ambient temperature.
The ADM1032 communicates over a 2-wire serial interface
compatible with System Management Bus (SMBus) standards.
Under/overtemperature limits can be programmed into the device over
the SMBus, and an ALERT
output signals when the onchip or remote
temperature measurement is out of range. This output can be used as
an interrupt or as a SMBus alert. The THERM
output is a comparator
output that allows CPU clock throttling or on/off control of a cooling
fan. An ADM10321 and ADM10322 are available. The difference
between the ADM1032 and the ADM10321 is the default value of
the external THERM
limit. The ADM10322 has a different SMBus
address. The SMBus address of the ADM10322 is 0x4D.
