System Temperature Monitor

ADM1032^*

PRODUCT DESCRIPTION

FEATURES

The ADM1032 is a dual-channel digital thermometer and

under/over temperature alarm, intended for use in personal

computers and thermal management systems. The higher 1°C

accuracy offered allows systems designers to safely reduce

temperature guardbanding and increase system performance.

The device can measure the temperature of a microprocessor

using a diode-connected NPN or PNP transistor, which may be

provided on-chip or can be a low-cost discrete device such as

the 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 mea-

sures the output of an on-chip temperature sensor, to monitor

the temperature of the device and its environment.

Small 8-Lead SO and Micro_SO Package

The ADM1032 communicates over a two-wire serial interface

compatible with System Management Bus (SMBus) standards.

Under and over temperature limits can be programmed into the

device over the serial bus, and an ALERT output signals when

the on-chip or remote temperature measurement is out of range.

This output can be used as an interrupt, or as an SMBus alert.

The THERM output is a comparator output that allows CPU

clock throttling or on/off control of a cooling fan.
