PRODUCT DESCRIPTION
The ADM1021A is a two-channel digital thermometer and under/
over temperature alarm, intended for use in personal computers
and other systems requiring thermal monitoring and management.
The device can measure the temperature of a microprocessor
using a diode-connected PNP transistor, which may be provided
on-chip in the case of the Pentium
III or similar processors,
or can be a low-cost discrete NPN/PNP device such as the
2N3904/2N3906. A novel measurement technique cancels out
the absolute value of the transistor’s base emitter voltage, so
that no calibration is required. The second measurement chan-
nel measures the output of an on-chip temperature sensor, to
monitor the temperature of the device and its environment.
The ADM1021A communicates over a two-wire serial interface
compatible with SMBus
standards. Under and over temperature
limits can be programmed into the devices over the serial bus,
and an
ALERT
output signals when the on-chip or remote
temperature is out of range. This output can be used as an inter-
rupt, or as an SMBus alert.
