PRODUCT DESCRIPTION
The ADM1023 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.
Optimized for the Pentium
III; the higher accuracy offered
allows systems designers to safely reduce temperature guard
banding and increase system performance. The device can
measure the temperature of a microprocessor using a diode-con-
nected 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 channel measures the
output of an on-chip temperature sensor, to monitor the tem-
perature of the device and its environment.
The ADM1023 communicates over a 2-wire serial interface
compatible with SMBus
standards. Under and over tempera-
ture limits can be programmed into the device 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
interrupt, or as an SMBus alert.
