ACPI-Compliant, High Accuracy  
Microprocessor System Temperature Monitor  
ADM1023  
FEATURES  
GENERAL DESCRIPTION  
The ADM10231 is a 2-channel digital thermometer and under-  
and overtemperature alarm for use in personal computers and  
other systems requiring thermal monitoring and management.  
Optimized for the Pentium® III, the higher accuracy allows  
Next generation upgrade of ADM1021  
On-chip and remote temperature sensing  
Offset registers for system calibration  
1°C accuracy and resolution on local channel  
0.125°C resolution/1°C accuracy on remote channel  
Programmable over/under temperature limits  
Programmable conversion rate  
systems designers to safely reduce temperature guard banding  
and increase system performance. The device can measure the  
temperature of a microprocessor using a diode-connected PNP  
transistor, which may be provided on-chip with the Pentium III  
or similar processors; or it 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 temperature of the device  
and its environment.  
ALERT  
Supports system management bus (SMBus)  
2-wire SMBus serial interface  
200 μA max operating current (0.25 conversions/second)  
1 μA standby current  
3 V to 5.5 V supply  
Small 16-lead QSOP package  
APPLICATIONS  
The ADM1023 communicates over a 2-wire serial interface  
compatible with SMBus standards. Under- and overtemperature  
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.
