Low Cost PC  
Hardware Monitor ASIC  
ADM1025/ADM1025A  
Preliminary Technical Data  
FEATURES  
Up to 8 measurement channels  
5 inputs to measure supply voltages  
PRODUCT DESCRIPTION  
The ADM1025/ADM1025A1 is a complete system hardware  
monitor for microprocessor-based systems, providing measure-  
ment and limit comparison of various system parameters. Five  
voltage measurement inputs are provided for monitoring 2.5 V,  
3.3 V, 5 V, and 12 V power supplies and the processor core  
voltage. The ADM1025/ADM1025A can monitor a sixth power  
supply voltage by measuring its own VCC. One input (two pins)  
is dedicated to a remote temperature-sensing diode, and an on-  
chip temperature sensor allows ambient temperature to be  
monitored. The ADM1025A has open-drain VID inputs while  
the ADM1025 has on-chip 100 kΩ pull-ups on the VID inputs.

CC monitored internally  
External temperature measurement with remote diode  
On-chip temperature sensor  
5 digital inputs for VID bits  
Integrated 100 kΩ pull-ups on VID pins (ADM1025 only)  
LDCM support  
I2C® compatible system management bus (SMBus)  
Programmable

Configurable offset for internal/external channel  
Shutdown mode to minimize power consumption  
Limit comparison of all monitored values  
RST  
INT  
output pin  
output pin  
Measured values and in/out of limit status can be read out via  
an I2C compatible serial System Management Bus. The device  
can be controlled and configured over the same serial bus. The  
device also has a programmable INT output to indicate  
undervoltage, overvoltage, and overtemperature conditions.  
APPLICATIONS  
Network servers and personal computers  
Microprocessor-based office equipment  
Test equipment and measuring instruments  
The ADM1025/ADM1025A’s 3.0 V to 5.5 V supply voltage  
range, low supply current, and I2C compatible 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.
