1 / 16 page Semiconductor Components Industries, LLC, 2012 April, 2012 − Rev. 10 1 Publication Order Number: ADM1023/D ADM1023 ACPI‐Compliant, High Accuracy Microprocessor System Temperature Monitor The ADM1023 is a 2-channel digital thermometer and under/overtemperature alarm for use in personal computers and other systems requiring thermal monitoring and management. Optimized for the Pentium III, the higher accuracy 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-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. The ADM1023 communicates over a 2-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.
