ADM1024ARUZ

Overview

The ADM1024ARUZ is a system hardware monitor manufactured by onsemi, housed in a 24-lead TSSOP package. It provides measurement and limit comparison of various system parameters via an SMBus interface. The device features a 10-bit ADC with up to nine configurable measurement channels for analog voltage, fan speed, or external temperature. Key specifications include a supply voltage range of 2.8 V to 5.5 V, internal sensor accuracy of ±3 °C (±2 °C at 25 °C), and external diode sensor accuracy of ±5 °C (±3 °C at 25 °C). It includes five digital VID inputs, chassis intrusion detection, and programmable interrupt outputs.

Feature Summary

• Supports sequential measurement of multiple analog and temperature channels with limit comparison capabilities.
• Integrates remote diode thermal sensing for precise external temperature monitoring.
• Features a System Management Bus (SMBus) interface for serial data communication and configuration.
• Includes dedicated inputs for processor core voltage identification (VID) and chassis intrusion detection.

Applications

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