ADM1021A  
Low Cost Microprocessor  
System Temperature  
Monitor Microcomputer  
The ADM1021A is a two−channel digital thermometer and  
under/overtemperature 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 can be provided on−chip with  
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 temperature of the device and its environment.  
The ADM1021A communicates over a two−wire serial interface  
compatible with SMBus standards. Under/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.
