ADM1024

System Hardware Monitor

with Remote Diode Thermal

Sensing

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; three are dedicated to monitoring 5.0 V and 12 V power

supplies and the processor core voltage. The ADM1024 can monitor a

fourth power supply voltage by measuring its own V . One input

TSSOP−24

CASE 948H

(two pins) is dedicated to a remote temperature−sensing 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 temperature−sensing

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 out−of−limit 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.
