1 / 30 page © Semiconductor Components Industries, LLC, 2016 January, 2016 − Rev. 5 1 Publication Order Number: ADM1024/D 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.
