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 VCC. One input
(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.
