ADM1024  
System Hardware Monitor  
with Remote Diode Thermal  
Sensing  
The ADM1024 is a complete system hardware monitor for  
microprocessorbased systems, providing measurement and limit  
comparison of various system parameters. Eight measurement inputs  
are provided; three are dedicated to monitoring 5.0 V and 12 V power  
supplies and the processor core voltage. The ADM1024 can monitor a  
http://onsemi.com  
fourth power supply voltage by measuring its own V . One input  
CC  
TSSOP24  
CASE 948H  
(two pins) is dedicated to a remote temperaturesensing diode. Two  
more pins can be configured as inputs to monitor a 2.5 V supply and a  
second processor core voltage, or as a second temperaturesensing  
input. The remaining two inputs can be programmed as general  
purpose analog inputs or as digital fan speed measuring inputs.  
Measured values can be read out via a serial System Management Bus  
and values for limit comparisons can be programmed in over the same  
serial bus. The high speed successive approximation ADC allows  
frequent sampling of all analog channels to ensure a fast interrupt  
response to any outoflimit measurement.

The ADM1024’s 2.8 V to 5.5 V supply voltage range, low supply  
current, and SMBus interface make it ideal for a wide range of  
applications. These include hardware monitoring and protection  
applications in personal computers, electronic test equipment, and office  
electronics.
