ADM1024ARUZ-R7

Overview

The ADM1024ARUZ-R7 is a system hardware monitor manufactured by onsemi, housed in a 24-lead TSSOP package. It features a 10-bit ADC with up to nine measurement channels for analog voltage, fan speed, and external temperature via remote diodes. The device operates within a supply voltage range of 2.8 V to 5.5 V and supports an SMBus interface with a clock frequency up to 400 kHz. Internal sensor accuracy is specified at ±3 °C from 0 °C to 100 °C, while the external diode sensor offers ±5 °C accuracy over the same range.

Feature Summary

• Provides comprehensive monitoring of power supplies, processor core voltages, and thermal conditions through multiple configurable input channels.
• Integrates a serial System Management Bus (SMBus) interface for digital communication, register configuration, and limit comparison functions.
• Includes dedicated pins for chassis intrusion detection and programmable reset outputs to enhance system security and control.

Applications

• Network Servers
• Personal Computers
• Microprocessor-Based Office Equipment

Procurement Notes

Verify component authenticity against official onsemi documentation before integration. Confirm that the specific R7 suffix corresponds to the required reel packaging format for your assembly line. Ensure the operating environment remains within the specified -40 °C to +100 °C temperature limits to maintain parameter accuracy.

Selection Notes

Select this component when a complete hardware monitoring solution with SMBus connectivity is required. It is suitable for designs needing simultaneous monitoring of multiple voltage rails and thermal sensors. Verify that the 24-lead TSSOP footprint aligns with the PCB layout constraints and that the 2.8 V to 5.5 V supply range matches the system power architecture.

Part Context

This part belongs to the ADM1024 family of system hardware monitors originally developed by Analog Devices and later acquired by onsemi. The series provides integrated sensing and management capabilities for microprocessor-based systems. The ARUZ-R7 designation indicates the industrial temperature grade, TSSOP-24 package, and tape-and-reel delivery method.

Replacement Considerations

Check for direct pin-compatible alternatives within the onsemi portfolio. Verify if newer revisions offer updated packaging or extended temperature ranges. Ensure any substitute maintains SMBus protocol compatibility and similar channel counts for seamless integration.
