ADM1024ARUZ-REEL7

Overview

The ADM1024ARUZ-REEL7 is a system hardware monitor manufactured by Analog Devices, distributed under the ON Semiconductor brand. It provides measurement and limit comparison of various system parameters for microprocessor-based systems via a System Management Bus (SMBus). The device features a 10-bit ADC with up to nine programmable measurement channels, including dedicated inputs for 5 V, 12 V, and processor core voltages. It supports remote diode thermal sensing on two channels and includes an on-chip temperature sensor. Operating within a supply voltage range of 2.8 V to 5.5 V, it offers low power consumption with a shutdown mode drawing as little as 45 µA.

Feature Summary

• Supports up to nine measurement channels configurable for analog voltage, fan speed, or external temperature monitoring.
• Includes dual remote diode inputs for precise external thermal sensing alongside an integrated bandgap temperature sensor.
• Features five digital VID inputs for reading processor voltage ID codes and chassis intrusion detection capabilities.
• Integrates an 8-bit DAC for analog output applications such as temperature-controlled fan regulation.

Applications

• Network Servers
• Personal Computers
• Microprocessor-Based Office Equipment
• Test Equipment and Measuring Instruments

Procurement Notes

Verify that the component matches the specific ordering code ADM1024ARUZ-REEL7 to ensure correct package type and temperature rating. Confirm compatibility with the System Management Bus protocol used in the target design. Check for any revisions or updates from the manufacturer regarding pinout or electrical specifications before finalizing procurement.

Selection Notes

Select this component when a complete hardware monitoring solution is required for microprocessor systems. Ensure the design utilizes the SMBus interface for communication. Verify that the available measurement channels cover all necessary voltage rails and thermal points. Consider the 2.8 V to 5.5 V operating range to match the system power supply architecture.

Part Context

The ADM1024 is part of the ADM1024 series of system hardware monitors produced by Analog Devices. This family of devices is designed for comprehensive system management in computing environments. The ARUZ suffix indicates a specific temperature grade and TSSOP-24 package configuration suitable for surface-mount assembly.

Replacement Considerations

Direct replacements may include other ADM1024 variants with different package options or temperature ranges. Verify functional equivalence regarding register maps and SMBus addressing if substituting with similar hardware monitors from Analog Devices or ON Semiconductor.
