PRODUCT DESCRIPTION  
The ADM1024 is a complete system hardware monitor for  
microprocessor-based systems, providing measurement and limit  
comparison of various system parameters. Eight measurement  
inputs are provided, of which three are dedicated to monitoring  
5 V and 12 V power supplies and the processor core voltage.  
The ADM1024 can monitor a fourth power-supply voltage by  
measuring its own VCC. One input (two pins) is dedicated to a  
On-Chip Temperature Sensor  
Five Digital Inputs for VID Bits  
LDCM Support  
System Management Bus (SMBus)  
Chassis Intrusion Detect  
Interrupt and Over Temperature Outputs  
Programmable RESET Input Pin  
Shutdown Mode to Minimize Power Consumption  
Limit Comparison of all Monitored Values  
remote temperature-sensing diode. Two further pins can be
